wish to reduce greenhouse gas emissions.
If vegetarianism is adopted by 2050, it would stave off about 7 million deaths per year, while
veganism would knock that estimate up to 8 million, thanks largely to a lessening of coronary
heart disease, diabetes, stroke and some cancers.
Experts suggest that food production accounts for one-quarter to one-third of all anthropogenic
greenhouse gas emissions worldwide, most of it because of the livestock industry. ?But just
eating a little less meat right now might make things a whole lot better for our children and
grandchildren.? ?When looking at what would be in line with avoiding dangerous levels of
climate change, we found that you could only stabilise the ratio of food-related emissions to all
emissions if everyone adopted a plant-based diet,? Springmann, a scientist, says. ?That scenario
is not very realistic ? but it highlights the importance that food-related emissions will play in the
future.? Research indicates that if everyone became vegetarian by 2050? largely thanks to the
elimination of red meat ? food-related emissions would drop by about 60%. With veganism
instead, emission declines would be around 70%.
Should we all go vegetarian, ideally we would dedicate at least 80% of that pastureland to the
restoration of grasslands and forests, which would capture carbon and further alleviate climate
change. Of course, people formerly engaged in the livestock industry would also need assistance
transitioning to a new career. Even those whose entire livelihoods do not depend on livestock
would stand to suffer. Meat is an important part of history, tradition and cultural identity. ?The
cultural impact of completely giving up meat would be very big, which is why efforts to reduce
meat consumption have often faltered,? are researcher says.

2)
wish to reduce greenhouse gas emissions.
If vegetarianism is adopted by 2050, it would stave off about 7 million deaths per year, while
veganism would knock that estimate up to 8 million, thanks largely to a lessening of coronary
heart disease, diabetes, stroke and some cancers.
Experts suggest that food production accounts for one-quarter to one-third of all anthropogenic
greenhouse gas emissions worldwide, most of it because of the livestock industry. ?But just
eating a little less meat right now might make things a whole lot better for our children and
grandchildren.? ?When looking at what would be in line with avoiding dangerous levels of
climate change, we found that you could only stabilise the ratio of food-related emissions to all
emissions if everyone adopted a plant-based diet,? Springmann, a scientist, says. ?That scenario
is not very realistic ? but it highlights the importance that food-related emissions will play in the
future.? Research indicates that if everyone became vegetarian by 2050? largely thanks to the
elimination of red meat ? food-related emissions would drop by about 60%. With veganism
instead, emission declines would be around 70%.
Should we all go vegetarian, ideally we would dedicate at least 80% of that pastureland to the
restoration of grasslands and forests, which would capture carbon and further alleviate climate
change. Of course, people formerly engaged in the livestock industry would also need assistance
transitioning to a new career. Even those whose entire livelihoods do not depend on livestock
would stand to suffer. Meat is an important part of history, tradition and cultural identity. ?The
cultural impact of completely giving up meat would be very big, which is why efforts to reduce
meat consumption have often faltered,? are researcher says.
Solution: moderation in meat-eating?s frequency and portion.
In fact, clear solutions already exist for reducing greenhouse gas emissions from the livestock
industry. What is lacking is the will to implement those changes.

only one option for each question:
Passage I
?Happiness is the consequence of personal effort. You fight for it, strive for it, insist upon it, and
sometimes even travel around the world looking for it,? writes Elizabeth Gilbert. ?You have to
participate relentlessly in the manifestations of your own blessings. And once you have achieved
a state of happiness, you must make a mighty effort to keep swimming upward into that
happiness forever, to stay afloat on top of it. If you don?t, you will leak away your innate
contentment.?
However, the latest scientific research suggests that such an attitude can also seriously backfire
for many people ? leading, for instance, to feelings of stress, loneliness, and personal failure.
According to this view, happiness is best seen as kind of timid bird: the harder you strive to catch
it, the further it flies away.
These findings help to explain the familiar stress and disappointment that some feel during
special events such as their birthday, Christmas or New Year?s Eve, or a wedding: the more you
wanted to enjoy every last moment, the less fun it became, whereas an unexpectedly good trip
somewhere nearby may have been a far more positive experience.
?once you stop chasing it, you might just find that it appears naturally of its own accord? means
that, Iris Mauss, a U.S. psychologist?s research has since shown that the desire for (and pursuit
of) happiness can also increase feelings of loneliness and disconnection, perhaps because it
causes you to focus your attention on yourself and your own feelings rather than appreciating

2)
wish to reduce greenhouse gas emissions.
If vegetarianism is adopted by 2050, it would stave off about 7 million deaths per year, while
veganism would knock that estimate up to 8 million, thanks largely to a lessening of coronary
heart disease, diabetes, stroke and some cancers.
Experts suggest that food production accounts for one-quarter to one-third of all anthropogenic
greenhouse gas emissions worldwide, most of it because of the livestock industry. ?But just
eating a little less meat right now might make things a whole lot better for our children and
grandchildren.? ?When looking at what would be in line with avoiding dangerous levels of
climate change, we found that you could only stabilise the ratio of food-related emissions to all
emissions if everyone adopted a plant-based diet,? Springmann, a scientist, says. ?That scenario
is not very realistic ? but it highlights the importance that food-related emissions will play in the
future.? Research indicates that if everyone became vegetarian by 2050? largely thanks to the
elimination of red meat ? food-related emissions would drop by about 60%. With veganism
instead, emission declines would be around 70%.
Should we all go vegetarian, ideally we would dedicate at least 80% of that pastureland to the
restoration of grasslands and forests, which would capture carbon and further alleviate climate
change. Of course, people formerly engaged in the livestock industry would also need assistance
transitioning to a new career. Even those whose entire livelihoods do not depend on livestock
would stand to suffer. Meat is an important part of history, tradition and cultural identity. ?The
cultural impact of completely giving up meat would be very big, which is why efforts to reduce
meat consumption have often faltered,? are researcher says.

Passage I
?Happiness is the consequence of personal effort. You fight for it, strive for it, insist upon it, and
sometimes even travel around the world looking for it,? writes Elizabeth Gilbert. ?You have to
participate relentlessly in the manifestations of your own blessings. And once you have achieved
a state of happiness, you must make a mighty effort to keep swimming upward into that
happiness forever, to stay afloat on top of it. If you don?t, you will leak away your innate
contentment.?
However, the latest scientific research suggests that such an attitude can also seriously backfire
for many people ? leading, for instance, to feelings of stress, loneliness, and personal failure.
According to this view, happiness is best seen as kind of timid bird: the harder you strive to catch
it, the further it flies away.
These findings help to explain the familiar stress and disappointment that some feel during
special events such as their birthday, Christmas or New Year?s Eve, or a wedding: the more you
wanted to enjoy every last moment, the less fun it became, whereas an unexpectedly good trip
somewhere nearby may have been a far more positive experience.
?once you stop chasing it, you might just find that it appears naturally of its own accord? means
that, Iris Mauss, a U.S. psychologist?s research has since shown that the desire for (and pursuit
of) happiness can also increase feelings of loneliness and disconnection, perhaps because it
causes you to focus your attention on yourself and your own feelings rather than appreciating
5)
the people around you. ?Self-focus might make me engage with other people less, and I might
judge other people more negatively if I perceive them to ?mess? with my happiness,? Mauss says.
?People might set very high standards for their own happiness as a function of this ? they may
think they should be happy all the time, or extremely happy, and that can set people up to feel
disappointed with themselves, that they fall short ? and that could have these self-defeating
effects.?
A study by Maglio, another researcher, has found that the conscious pursuit of happiness may
backfire ? it?s very difficult to feel that you?ve reached maximum happiness. Happiness really is
like a timid animal. And once you stop chasing it, you might just find that it appears naturally of
its own accord.

People become vegetarians for a variety of reasons. Some do it to alleviate animal suffering,
others because they want to pursue a healthier lifestyle. Still others are fans of sustainability or
2)
wish to reduce greenhouse gas emissions.
If vegetarianism is adopted by 2050, it would stave off about 7 million deaths per year, while
veganism would knock that estimate up to 8 million, thanks largely to a lessening of coronary
heart disease, diabetes, stroke and some cancers.
Experts suggest that food production accounts for one-quarter to one-third of all anthropogenic
greenhouse gas emissions worldwide, most of it because of the livestock industry. ?But just
eating a little less meat right now might make things a whole lot better for our children and
grandchildren.? ?When looking at what would be in line with avoiding dangerous levels of
climate change, we found that you could only stabilise the ratio of food-related emissions to all
emissions if everyone adopted a plant-based diet,? Springmann, a scientist, says. ?That scenario
is not very realistic ? but it highlights the importance that food-related emissions will play in the
future.? Research indicates that if everyone became vegetarian by 2050? largely thanks to the
elimination of red meat ? food-related emissions would drop by about 60%. With veganism
instead, emission declines would be around 70%.
Should we all go vegetarian, ideally we would dedicate at least 80% of that pastureland to the
restoration of grasslands and forests, which would capture carbon and further alleviate climate
change. Of course, people formerly engaged in the livestock industry would also need assistance
transitioning to a new career. Even those whose entire livelihoods do not depend on livestock
would stand to suffer. Meat is an important part of history, tradition and cultural identity. ?The
cultural impact of completely giving up meat would be very big, which is why efforts to reduce
meat consumption have often faltered,? are researcher says.
Solution: moderation in meat-eating?s frequency and portion.

industry. What is lacking is the will to implement those changes.

?Happiness is the consequence of personal effort. You fight for it, strive for it, insist upon it, and
sometimes even travel around the world looking for it,? writes Elizabeth Gilbert. ?You have to
participate relentlessly in the manifestations of your own blessings. And once you have achieved
a state of happiness, you must make a mighty effort to keep swimming upward into that
happiness forever, to stay afloat on top of it. If you don?t, you will leak away your innate
contentment.?
However, the latest scientific research suggests that such an attitude can also seriously backfire
for many people ? leading, for instance, to feelings of stress, loneliness, and personal failure.
According to this view, happiness is best seen as kind of timid bird: the harder you strive to catch
it, the further it flies away.
These findings help to explain the familiar stress and disappointment that some feel during
special events such as their birthday, Christmas or New Year?s Eve, or a wedding: the more you
wanted to enjoy every last moment, the less fun it became, whereas an unexpectedly good trip
somewhere nearby may have been a far more positive experience.
?once you stop chasing it, you might just find that it appears naturally of its own accord? means
that, Iris Mauss, a U.S. psychologist?s research has since shown that the desire for (and pursuit
of) happiness can also increase feelings of loneliness and disconnection, perhaps because it
causes you to focus your attention on yourself and your own feelings rather than appreciating
5)
the people around you. ?Self-focus might make me engage with other people less, and I might
judge other people more negatively if I perceive them to ?mess? with my happiness,? Mauss says.
?People might set very high standards for their own happiness as a function of this ? they may
think they should be happy all the time, or extremely happy, and that can set people up to feel
disappointed with themselves, that they fall short ? and that could have these self-defeating
effects.?
A study by Maglio, another researcher, has found that the conscious pursuit of happiness may
backfire ? it?s very difficult to feel that you?ve reached maximum happiness. Happiness really is
like a timid animal. And once you stop chasing it, you might just find that it appears naturally of
its own accord.

People become vegetarians for a variety of reasons. Some do it to alleviate animal suffering,
others because they want to pursue a healthier lifestyle. Still others are fans of sustainability or
2)
wish to reduce greenhouse gas emissions.
If vegetarianism is adopted by 2050, it would stave off about 7 million deaths per year, while
veganism would knock that estimate up to 8 million, thanks largely to a lessening of coronary
heart disease, diabetes, stroke and some cancers.
Experts suggest that food production accounts for one-quarter to one-third of all anthropogenic
greenhouse gas emissions worldwide, most of it because of the livestock industry. ?But just
eating a little less meat right now might make things a whole lot better for our children and
grandchildren.? ?When looking at what would be in line with avoiding dangerous levels of
climate change, we found that you could only stabilise the ratio of food-related emissions to all
emissions if everyone adopted a plant-based diet,? Springmann, a scientist, says. ?That scenario
is not very realistic ? but it highlights the importance that food-related emissions will play in the
future.? Research indicates that if everyone became vegetarian by 2050? largely thanks to the
elimination of red meat ? food-related emissions would drop by about 60%. With veganism
instead, emission declines would be around 70%.
Should we all go vegetarian, ideally we would dedicate at least 80% of that pastureland to the
restoration of grasslands and forests, which would capture carbon and further alleviate climate
change. Of course, people formerly engaged in the livestock industry would also need assistance
transitioning to a new career. Even those whose entire livelihoods do not depend on livestock
would stand to suffer. Meat is an important part of history, tradition and cultural identity. ?The
cultural impact of completely giving up meat would be very big, which is why efforts to reduce
meat consumption have often faltered,? are researcher says.
Solution: moderation in meat-eating?s frequency and portion.
In fact, clear solutions already exist for reducing greenhouse gas emissions from the livestock
industry. What is lacking is the will to implement those changes.

?Happiness is the consequence of personal effort. You fight for it, strive for it, insist upon it, and
sometimes even travel around the world looking for it,? writes Elizabeth Gilbert. ?You have to
participate relentlessly in the manifestations of your own blessings. And once you have achieved
a state of happiness, you must make a mighty effort to keep swimming upward into that
happiness forever, to stay afloat on top of it. If you don?t, you will leak away your innate
contentment.?
However, the latest scientific research suggests that such an attitude can also seriously backfire
for many people ? leading, for instance, to feelings of stress, loneliness, and personal failure.
According to this view, happiness is best seen as kind of timid bird: the harder you strive to catch
it, the further it flies away.
These findings help to explain the familiar stress and disappointment that some feel during
special events such as their birthday, Christmas or New Year?s Eve, or a wedding: the more you
wanted to enjoy every last moment, the less fun it became, whereas an unexpectedly good trip
somewhere nearby may have been a far more positive experience.
?once you stop chasing it, you might just find that it appears naturally of its own accord? means
that, Iris Mauss, a U.S. psychologist?s research has since shown that the desire for (and pursuit
of) happiness can also increase feelings of loneliness and disconnection, perhaps because it
causes you to focus your attention on yourself and your own feelings rather than appreciating
5)
the people around you. ?Self-focus might make me engage with other people less, and I might
judge other people more negatively if I perceive them to ?mess? with my happiness,? Mauss says.
?People might set very high standards for their own happiness as a function of this ? they may
think they should be happy all the time, or extremely happy, and that can set people up to feel
disappointed with themselves, that they fall short ? and that could have these self-defeating
effects.?
A study by Maglio, another researcher, has found that the conscious pursuit of happiness may
backfire ? it?s very difficult to feel that you?ve reached maximum happiness. Happiness really is
like a timid animal. And once you stop chasing it, you might just find that it appears naturally of
its own accord.

wish to reduce greenhouse gas emissions.
If vegetarianism is adopted by 2050, it would stave off about 7 million deaths per year, while
veganism would knock that estimate up to 8 million, thanks largely to a lessening of coronary
heart disease, diabetes, stroke and some cancers.
Experts suggest that food production accounts for one-quarter to one-third of all anthropogenic
greenhouse gas emissions worldwide, most of it because of the livestock industry. ?But just
eating a little less meat right now might make things a whole lot better for our children and
grandchildren.? ?When looking at what would be in line with avoiding dangerous levels of
climate change, we found that you could only stabilise the ratio of food-related emissions to all
emissions if everyone adopted a plant-based diet,? Springmann, a scientist, says. ?That scenario
is not very realistic ? but it highlights the importance that food-related emissions will play in the
future.? Research indicates that if everyone became vegetarian by 2050? largely thanks to the
elimination of red meat ? food-related emissions would drop by about 60%. With veganism
instead, emission declines would be around 70%.
Should we all go vegetarian, ideally we would dedicate at least 80% of that pastureland to the
restoration of grasslands and forests, which would capture carbon and further alleviate climate
change. Of course, people formerly engaged in the livestock industry would also need assistance
transitioning to a new career. Even those whose entire livelihoods do not depend on livestock
would stand to suffer. Meat is an important part of history, tradition and cultural identity. ?The
cultural impact of completely giving up meat would be very big, which is why efforts to reduce
meat consumption have often faltered,? are researcher says.

?Happiness is the consequence of personal effort. You fight for it, strive for it, insist upon it, and
sometimes even travel around the world looking for it,? writes Elizabeth Gilbert. ?You have to
participate relentlessly in the manifestations of your own blessings. And once you have achieved
a state of happiness, you must make a mighty effort to keep swimming upward into that
happiness forever, to stay afloat on top of it. If you don?t, you will leak away your innate
contentment.?
However, the latest scientific research suggests that such an attitude can also seriously backfire
for many people ? leading, for instance, to feelings of stress, loneliness, and personal failure.
According to this view, happiness is best seen as kind of timid bird: the harder you strive to catch
it, the further it flies away.
These findings help to explain the familiar stress and disappointment that some feel during
special events such as their birthday, Christmas or New Year?s Eve, or a wedding: the more you
wanted to enjoy every last moment, the less fun it became, whereas an unexpectedly good trip
somewhere nearby may have been a far more positive experience.
?once you stop chasing it, you might just find that it appears naturally of its own accord? means
that, Iris Mauss, a U.S. psychologist?s research has since shown that the desire for (and pursuit
of) happiness can also increase feelings of loneliness and disconnection, perhaps because it
causes you to focus your attention on yourself and your own feelings rather than appreciating
5)
the people around you. ?Self-focus might make me engage with other people less, and I might
judge other people more negatively if I perceive them to ?mess? with my happiness,? Mauss says.
?People might set very high standards for their own happiness as a function of this ? they may
think they should be happy all the time, or extremely happy, and that can set people up to feel
disappointed with themselves, that they fall short ? and that could have these self-defeating
effects.?
A study by Maglio, another researcher, has found that the conscious pursuit of happiness may
backfire ? it?s very difficult to feel that you?ve reached maximum happiness. Happiness really is
like a timid animal. And once you stop chasing it, you might just find that it appears naturally of
its own accord.

The manner in which instruction is imparted in our schools and colleges has not changed
much from the 20th century to the 21st century. Much of the knowledge is taught in our schools
and colleges today prepares the student to pass examinations but not to analyse the knowledge
in a context and apply that knowledge to practical problems. No wonder that many of the
information technology firms that go to engineering colleges for campus recruitment find that
90% of the candidates are unfit for jobs.
A noted educator in a Ted talk explained why judging students based on marks obtained in
examinations is amiss. A student who obtains 60% marks in an examination passes out in first
class. He is lauded for his achievement. But he still has a 40% deficit. He compares this situation
to a motor car running with three wheels. To be able to be a truly knowledgeable person, one has
tointernalise the concepts with his already known knowledge, build on them and apply them. If
you know only 40% or 60% of your curriculum, you miss the connections that link you to the
whole, and the 60% knowledge which is partial will be of no use.
A fundamental thing missing from our schools and colleges is the context. A student is taught
knowledge given in the books. But the student has to apply that knowledge in the society or
community in which he lives. How well he communicates his ideas to others, how well he
understands his emotions and emotions of others, to know how human psyche works and how to
work in a team are all paramount to navigate life. These skills are not taught in schools or
colleges.
How to provide a holistic and useful education to the young generation? It has to be through
parental awareness about what their progeny are missing in schools and colleges. Parents and
educationists may do well to note the words of Albert Einstein on the true purpose of education.
?The value of college education is not the learning of many facts but the training of the mind to
think.?

People become vegetarians for a variety of reasons. Some do it to alleviate animal suffering,
others because they want to pursue a healthier lifestyle. Still others are fans of sustainability or
2)
wish to reduce greenhouse gas emissions.
If vegetarianism is adopted by 2050, it would stave off about 7 million deaths per year, while
veganism would knock that estimate up to 8 million, thanks largely to a lessening of coronary
heart disease, diabetes, stroke and some cancers.
Experts suggest that food production accounts for one-quarter to one-third of all anthropogenic
greenhouse gas emissions worldwide, most of it because of the livestock industry. ?But just
eating a little less meat right now might make things a whole lot better for our children and
grandchildren.? ?When looking at what would be in line with avoiding dangerous levels of
climate change, we found that you could only stabilise the ratio of food-related emissions to all
emissions if everyone adopted a plant-based diet,? Springmann, a scientist, says. ?That scenario
is not very realistic ? but it highlights the importance that food-related emissions will play in the
future.? Research indicates that if everyone became vegetarian by 2050? largely thanks to the
elimination of red meat ? food-related emissions would drop by about 60%. With veganism
instead, emission declines would be around 70%.
Should we all go vegetarian, ideally we would dedicate at least 80% of that pastureland to the
restoration of grasslands and forests, which would capture carbon and further alleviate climate
change. Of course, people formerly engaged in the livestock industry would also need assistance
transitioning to a new career. Even those whose entire livelihoods do not depend on livestock
would stand to suffer. Meat is an important part of history, tradition and cultural identity. ?The
cultural impact of completely giving up meat would be very big, which is why efforts to reduce
meat consumption have often faltered,? are researcher says.
Solution: moderation in meat-eating?s frequency and portion.
In fact, clear solutions already exist for reducing greenhouse gas emissions from the livestock
industry. What is lacking is the will to implement those changes.

?Happiness is the consequence of personal effort. You fight for it, strive for it, insist upon it, and
sometimes even travel around the world looking for it,? writes Elizabeth Gilbert. ?You have to
participate relentlessly in the manifestations of your own blessings. And once you have achieved
a state of happiness, you must make a mighty effort to keep swimming upward into that
happiness forever, to stay afloat on top of it. If you don?t, you will leak away your innate
contentment.?
However, the latest scientific research suggests that such an attitude can also seriously backfire
for many people ? leading, for instance, to feelings of stress, loneliness, and personal failure.
According to this view, happiness is best seen as kind of timid bird: the harder you strive to catch
it, the further it flies away.
These findings help to explain the familiar stress and disappointment that some feel during
special events such as their birthday, Christmas or New Year?s Eve, or a wedding: the more you
wanted to enjoy every last moment, the less fun it became, whereas an unexpectedly good trip
somewhere nearby may have been a far more positive experience.
?once you stop chasing it, you might just find that it appears naturally of its own accord? means
that, Iris Mauss, a U.S. psychologist?s research has since shown that the desire for (and pursuit
of) happiness can also increase feelings of loneliness and disconnection, perhaps because it
causes you to focus your attention on yourself and your own feelings rather than appreciating
5)
the people around you. ?Self-focus might make me engage with other people less, and I might
judge other people more negatively if I perceive them to ?mess? with my happiness,? Mauss says.
?People might set very high standards for their own happiness as a function of this ? they may
think they should be happy all the time, or extremely happy, and that can set people up to feel
disappointed with themselves, that they fall short ? and that could have these self-defeating
effects.?
A study by Maglio, another researcher, has found that the conscious pursuit of happiness may
backfire ? it?s very difficult to feel that you?ve reached maximum happiness. Happiness really is
like a timid animal. And once you stop chasing it, you might just find that it appears naturally of
its own accord.

The manner in which instruction is imparted in our schools and colleges has not changed
much from the 20th century to the 21st century. Much of the knowledge is taught in our schools
and colleges today prepares the student to pass examinations but not to analyse the knowledge
in a context and apply that knowledge to practical problems. No wonder that many of the
information technology firms that go to engineering colleges for campus recruitment find that
90% of the candidates are unfit for jobs.
A noted educator in a Ted talk explained why judging students based on marks obtained in
examinations is amiss. A student who obtains 60% marks in an examination passes out in first
class. He is lauded for his achievement. But he still has a 40% deficit. He compares this situation
to a motor car running with three wheels. To be able to be a truly knowledgeable person, one has
tointernalise the concepts with his already known knowledge, build on them and apply them. If
you know only 40% or 60% of your curriculum, you miss the connections that link you to the
whole, and the 60% knowledge which is partial will be of no use.
A fundamental thing missing from our schools and colleges is the context. A student is taught
knowledge given in the books. But the student has to apply that knowledge in the society or
community in which he lives. How well he communicates his ideas to others, how well he
understands his emotions and emotions of others, to know how human psyche works and how to
work in a team are all paramount to navigate life. These skills are not taught in schools or
colleges.
How to provide a holistic and useful education to the young generation? It has to be through
parental awareness about what their progeny are missing in schools and colleges. Parents and
educationists may do well to note the words of Albert Einstein on the true purpose of education.
?The value of college education is not the learning of many facts but the training of the mind to

[Question ID = 25469]

2. It has not changed much from the 20th century to the 21st century. [Option ID = 41871]
3. Students passing out from engineering colleges are unfit for jobs [Option ID = 41873]
4. All of these [Option ID = 41874]
Correct Answer :-
It has not changed much from the 20th century to the 21st century. [Option ID = 41871]
The manner in which instruction is imparted in our schools and colleges has not changed
much from the 20th century to the 21st century. Much of the knowledge is taught in our schools
and colleges today prepares the student to pass examinations but not to analyse the knowledge
in a context and apply that knowledge to practical problems. No wonder that many of the
information technology firms that go to engineering colleges for campus recruitment find that
90% of the candidates are unfit for jobs.
A noted educator in a Ted talk explained why judging students based on marks obtained in
examinations is amiss. A student who obtains 60% marks in an examination passes out in first
class. He is lauded for his achievement. But he still has a 40% deficit. He compares this situation
to a motor car running with three wheels. To be able to be a truly knowledgeable person, one has
tointernalise the concepts with his already known knowledge, build on them and apply them. If

If vegetarianism is adopted by 2050, it would stave off about 7 million deaths per year, while
veganism would knock that estimate up to 8 million, thanks largely to a lessening of coronary
heart disease, diabetes, stroke and some cancers.
Experts suggest that food production accounts for one-quarter to one-third of all anthropogenic
greenhouse gas emissions worldwide, most of it because of the livestock industry. ?But just
eating a little less meat right now might make things a whole lot better for our children and
grandchildren.? ?When looking at what would be in line with avoiding dangerous levels of
climate change, we found that you could only stabilise the ratio of food-related emissions to all
emissions if everyone adopted a plant-based diet,? Springmann, a scientist, says. ?That scenario

future.? Research indicates that if everyone became vegetarian by 2050? largely thanks to the
elimination of red meat ? food-related emissions would drop by about 60%. With veganism
instead, emission declines would be around 70%.
Should we all go vegetarian, ideally we would dedicate at least 80% of that pastureland to the

?Happiness is the consequence of personal effort. You fight for it, strive for it, insist upon it, and
sometimes even travel around the world looking for it,? writes Elizabeth Gilbert. ?You have to
participate relentlessly in the manifestations of your own blessings. And once you have achieved
a state of happiness, you must make a mighty effort to keep swimming upward into that
happiness forever, to stay afloat on top of it. If you don?t, you will leak away your innate
contentment.?
However, the latest scientific research suggests that such an attitude can also seriously backfire
for many people ? leading, for instance, to feelings of stress, loneliness, and personal failure.
According to this view, happiness is best seen as kind of timid bird: the harder you strive to catch
it, the further it flies away.
These findings help to explain the familiar stress and disappointment that some feel during
special events such as their birthday, Christmas or New Year?s Eve, or a wedding: the more you
wanted to enjoy every last moment, the less fun it became, whereas an unexpectedly good trip
somewhere nearby may have been a far more positive experience.
?once you stop chasing it, you might just find that it appears naturally of its own accord? means
that, Iris Mauss, a U.S. psychologist?s research has since shown that the desire for (and pursuit
of) happiness can also increase feelings of loneliness and disconnection, perhaps because it
causes you to focus your attention on yourself and your own feelings rather than appreciating
5)
the people around you. ?Self-focus might make me engage with other people less, and I might
judge other people more negatively if I perceive them to ?mess? with my happiness,? Mauss says.
?People might set very high standards for their own happiness as a function of this ? they may
think they should be happy all the time, or extremely happy, and that can set people up to feel
disappointed with themselves, that they fall short ? and that could have these self-defeating
effects.?
A study by Maglio, another researcher, has found that the conscious pursuit of happiness may
backfire ? it?s very difficult to feel that you?ve reached maximum happiness. Happiness really is
like a timid animal. And once you stop chasing it, you might just find that it appears naturally of

A study by Maglio, another researcher, has found that the conscious pursuit of happiness may
backfire ? it?s very difficult to feel that you?ve reached maximum happiness. Happiness really is
like a timid animal. And once you stop chasing it, you might just find that it appears naturally of
its own accord.

only one option for each question:
Passage I
?Happiness is the consequence of personal effort. You fight for it, strive for it, insist upon it, and
sometimes even travel around the world looking for it,? writes Elizabeth Gilbert. ?You have to
participate relentlessly in the manifestations of your own blessings. And once you have achieved
a state of happiness, you must make a mighty effort to keep swimming upward into that
happiness forever, to stay afloat on top of it. If you don?t, you will leak away your innate
contentment.?
However, the latest scientific research suggests that such an attitude can also seriously backfire
for many people ? leading, for instance, to feelings of stress, loneliness, and personal failure.
According to this view, happiness is best seen as kind of timid bird: the harder you strive to catch
it, the further it flies away.
These findings help to explain the familiar stress and disappointment that some feel during
special events such as their birthday, Christmas or New Year?s Eve, or a wedding: the more you
wanted to enjoy every last moment, the less fun it became, whereas an unexpectedly good trip
somewhere nearby may have been a far more positive experience.
Iris Mauss, a U.S. psychologist?s research has since shown that the desire for (and pursuit of)
happiness can also increase feelings of loneliness and disconnection, perhaps because it causes
you to focus your attention on yourself and your own feelings rather than appreciating the
people around you. ?Self-focus might make me engage with other people less, and I might judge
other people more negatively if I perceive them to ?mess? with my happiness,? Mauss says.
?People might set very high standards for their own happiness as a function of this ? they may
think they should be happy all the time, or extremely happy, and that can set people up to feel
disappointed with themselves, that they fall short ? and that could have these self-defeating
effects.?

The manner in which instruction is imparted in our schools and colleges has not changed
much from the 20th century to the 21st century. Much of the knowledge is taught in our schools
and colleges today prepares the student to pass examinations but not to analyse the knowledge
in a context and apply that knowledge to practical problems. No wonder that many of the
information technology firms that go to engineering colleges for campus recruitment find that
90% of the candidates are unfit for jobs.
A noted educator in a Ted talk explained why judging students based on marks obtained in
examinations is amiss. A student who obtains 60% marks in an examination passes out in first
class. He is lauded for his achievement. But he still has a 40% deficit. He compares this situation
to a motor car running with three wheels. To be able to be a truly knowledgeable person, one has
tointernalise the concepts with his already known knowledge, build on them and apply them. If
you know only 40% or 60% of your curriculum, you miss the connections that link you to the
whole, and the 60% knowledge which is partial will be of no use.
A fundamental thing missing from our schools and colleges is the context. A student is taught
knowledge given in the books. But the student has to apply that knowledge in the society or
community in which he lives. How well he communicates his ideas to others, how well he
understands his emotions and emotions of others, to know how human psyche works and how to
work in a team are all paramount to navigate life. These skills are not taught in schools or
colleges.
How to provide a holistic and useful education to the young generation? It has to be through
parental awareness about what their progeny are missing in schools and colleges. Parents and
educationists may do well to note the words of Albert Einstein on the true purpose of education.
?The value of college education is not the learning of many facts but the training of the mind to
think.?

wish to reduce greenhouse gas emissions.
If vegetarianism is adopted by 2050, it would stave off about 7 million deaths per year, while
veganism would knock that estimate up to 8 million, thanks largely to a lessening of coronary
heart disease, diabetes, stroke and some cancers.
Experts suggest that food production accounts for one-quarter to one-third of all anthropogenic
greenhouse gas emissions worldwide, most of it because of the livestock industry. ?But just
eating a little less meat right now might make things a whole lot better for our children and
grandchildren.? ?When looking at what would be in line with avoiding dangerous levels of
climate change, we found that you could only stabilise the ratio of food-related emissions to all
emissions if everyone adopted a plant-based diet,? Springmann, a scientist, says. ?That scenario
is not very realistic ? but it highlights the importance that food-related emissions will play in the
future.? Research indicates that if everyone became vegetarian by 2050? largely thanks to the
elimination of red meat ? food-related emissions would drop by about 60%. With veganism
instead, emission declines would be around 70%.
Should we all go vegetarian, ideally we would dedicate at least 80% of that pastureland to the
restoration of grasslands and forests, which would capture carbon and further alleviate climate
change. Of course, people formerly engaged in the livestock industry would also need assistance
transitioning to a new career. Even those whose entire livelihoods do not depend on livestock

Mark the statement that is NOT true:
[Question ID = 25468]
1. Livestock is responsible for generation of a large amount of greenhouse gases [Option ID = 41867]
2. Most diseases would vanish if we did not eat meat [Option ID = 41868]
3. We are not interested in reducing greenhouse gas emissions from the livestock industry [Option ID =
41869]
4. You could only stabilise the ratio of food-related emissions to all emissions if everyone became a vegetarian
[Option ID = 41870]
Correct Answer :-
Livestock is responsible for generation of a large amount of greenhouse gases [Option ID = 41867]
People become vegetarians for a variety of reasons. Some do it to alleviate animal suffering,
others because they want to pursue a healthier lifestyle. Still others are fans of sustainability or
wish to reduce greenhouse gas emissions.
If vegetarianism is adopted by 2050, it would stave off about 7 million deaths per year, while
veganism would knock that estimate up to 8 million, thanks largely to a lessening of coronary
heart disease, diabetes, stroke and some cancers.
Experts suggest that food production accounts for one-quarter to one-third of all anthropogenic
greenhouse gas emissions worldwide, most of it because of the livestock industry. ?But just
eating a little less meat right now might make things a whole lot better for our children and
grandchildren.? ?When looking at what would be in line with avoiding dangerous levels of
climate change, we found that you could only stabilise the ratio of food-related emissions to all
emissions if everyone adopted a plant-based diet,? Springmann, a scientist, says. ?That scenario
is not very realistic ? but it highlights the importance that food-related emissions will play in the
future.? Research indicates that if everyone became vegetarian by 2050? largely thanks to the
4)
elimination of red meat ? food-related emissions would drop by about 60%. With veganism
instead, emission declines would be around 70%.
Should we all go vegetarian, ideally we would dedicate at least 80% of that pastureland to the
restoration of grasslands and forests, which would capture carbon and further alleviate climate
change. Of course, people formerly engaged in the livestock industry would also need assistance
transitioning to a new career. Even those whose entire livelihoods do not depend on livestock
would stand to suffer. Meat is an important part of history, tradition and cultural identity. ?The
cultural impact of completely giving up meat would be very big, which is why efforts to reduce
meat consumption have often faltered,? are researcher says.
Solution: moderation in meat-eating?s frequency and portion.
In fact, clear solutions already exist for reducing greenhouse gas emissions from the livestock
industry. What is lacking is the will to implement those changes.
Why does the author think it is unrealistic to expect everyone to adopt vegetarianism?
[Question ID = 25467]
1. Livelihoods of billions of people depend on meat industry [Option ID = 41865]
2. People are not convinced about the need to change their food habits [Option ID = 41864]
3. Meat is an inalienable part of our culture and history [Option ID = 41866]

?Happiness is the consequence of personal effort. You fight for it, strive for it, insist upon it, and
sometimes even travel around the world looking for it,? writes Elizabeth Gilbert. ?You have to
participate relentlessly in the manifestations of your own blessings. And once you have achieved
a state of happiness, you must make a mighty effort to keep swimming upward into that
happiness forever, to stay afloat on top of it. If you don?t, you will leak away your innate
contentment.?
However, the latest scientific research suggests that such an attitude can also seriously backfire
for many people ? leading, for instance, to feelings of stress, loneliness, and personal failure.
According to this view, happiness is best seen as kind of timid bird: the harder you strive to catch
it, the further it flies away.
These findings help to explain the familiar stress and disappointment that some feel during
special events such as their birthday, Christmas or New Year?s Eve, or a wedding: the more you
wanted to enjoy every last moment, the less fun it became, whereas an unexpectedly good trip
somewhere nearby may have been a far more positive experience.
?once you stop chasing it, you might just find that it appears naturally of its own accord? means
that, Iris Mauss, a U.S. psychologist?s research has since shown that the desire for (and pursuit
of) happiness can also increase feelings of loneliness and disconnection, perhaps because it
causes you to focus your attention on yourself and your own feelings rather than appreciating
5)
the people around you. ?Self-focus might make me engage with other people less, and I might
judge other people more negatively if I perceive them to ?mess? with my happiness,? Mauss says.
?People might set very high standards for their own happiness as a function of this ? they may
think they should be happy all the time, or extremely happy, and that can set people up to feel
disappointed with themselves, that they fall short ? and that could have these self-defeating
effects.?
A study by Maglio, another researcher, has found that the conscious pursuit of happiness may
backfire ? it?s very difficult to feel that you?ve reached maximum happiness. Happiness really is
like a timid animal. And once you stop chasing it, you might just find that it appears naturally of
its own accord.

The manner in which instruction is imparted in our schools and colleges has not changed
much from the 20th century to the 21st century. Much of the knowledge is taught in our schools
and colleges today prepares the student to pass examinations but not to analyse the knowledge
in a context and apply that knowledge to practical problems. No wonder that many of the
information technology firms that go to engineering colleges for campus recruitment find that
90% of the candidates are unfit for jobs.
A noted educator in a Ted talk explained why judging students based on marks obtained in
examinations is amiss. A student who obtains 60% marks in an examination passes out in first
class. He is lauded for his achievement. But he still has a 40% deficit. He compares this situation
to a motor car running with three wheels. To be able to be a truly knowledgeable person, one has
tointernalise the concepts with his already known knowledge, build on them and apply them. If
you know only 40% or 60% of your curriculum, you miss the connections that link you to the
whole, and the 60% knowledge which is partial will be of no use.
A fundamental thing missing from our schools and colleges is the context. A student is taught
knowledge given in the books. But the student has to apply that knowledge in the society or
community in which he lives. How well he communicates his ideas to others, how well he
understands his emotions and emotions of others, to know how human psyche works and how to
work in a team are all paramount to navigate life. These skills are not taught in schools or
colleges.
How to provide a holistic and useful education to the young generation? It has to be through
parental awareness about what their progeny are missing in schools and colleges. Parents and

People become vegetarians for a variety of reasons. Some do it to alleviate animal suffering,
others because they want to pursue a healthier lifestyle. Still others are fans of sustainability or
2)
wish to reduce greenhouse gas emissions.
If vegetarianism is adopted by 2050, it would stave off about 7 million deaths per year, while
veganism would knock that estimate up to 8 million, thanks largely to a lessening of coronary
heart disease, diabetes, stroke and some cancers.
Experts suggest that food production accounts for one-quarter to one-third of all anthropogenic
greenhouse gas emissions worldwide, most of it because of the livestock industry. ?But just
eating a little less meat right now might make things a whole lot better for our children and
grandchildren.? ?When looking at what would be in line with avoiding dangerous levels of
climate change, we found that you could only stabilise the ratio of food-related emissions to all
emissions if everyone adopted a plant-based diet,? Springmann, a scientist, says. ?That scenario
is not very realistic ? but it highlights the importance that food-related emissions will play in the
future.? Research indicates that if everyone became vegetarian by 2050? largely thanks to the
elimination of red meat ? food-related emissions would drop by about 60%. With veganism
instead, emission declines would be around 70%.
Should we all go vegetarian, ideally we would dedicate at least 80% of that pastureland to the
restoration of grasslands and forests, which would capture carbon and further alleviate climate
change. Of course, people formerly engaged in the livestock industry would also need assistance
transitioning to a new career. Even those whose entire livelihoods do not depend on livestock
would stand to suffer. Meat is an important part of history, tradition and cultural identity. ?The
cultural impact of completely giving up meat would be very big, which is why efforts to reduce
meat consumption have often faltered,? are researcher says.
Solution: moderation in meat-eating?s frequency and portion.
In fact, clear solutions already exist for reducing greenhouse gas emissions from the livestock
industry. What is lacking is the will to implement those changes.

?Happiness is the consequence of personal effort. You fight for it, strive for it, insist upon it, and
sometimes even travel around the world looking for it,? writes Elizabeth Gilbert. ?You have to
participate relentlessly in the manifestations of your own blessings. And once you have achieved
a state of happiness, you must make a mighty effort to keep swimming upward into that
happiness forever, to stay afloat on top of it. If you don?t, you will leak away your innate
contentment.?
However, the latest scientific research suggests that such an attitude can also seriously backfire
for many people ? leading, for instance, to feelings of stress, loneliness, and personal failure.
According to this view, happiness is best seen as kind of timid bird: the harder you strive to catch
it, the further it flies away.
These findings help to explain the familiar stress and disappointment that some feel during
special events such as their birthday, Christmas or New Year?s Eve, or a wedding: the more you
wanted to enjoy every last moment, the less fun it became, whereas an unexpectedly good trip
somewhere nearby may have been a far more positive experience.
?once you stop chasing it, you might just find that it appears naturally of its own accord? means
that, Iris Mauss, a U.S. psychologist?s research has since shown that the desire for (and pursuit
of) happiness can also increase feelings of loneliness and disconnection, perhaps because it
causes you to focus your attention on yourself and your own feelings rather than appreciating
5)
the people around you. ?Self-focus might make me engage with other people less, and I might
judge other people more negatively if I perceive them to ?mess? with my happiness,? Mauss says.
?People might set very high standards for their own happiness as a function of this ? they may
think they should be happy all the time, or extremely happy, and that can set people up to feel
disappointed with themselves, that they fall short ? and that could have these self-defeating
effects.?
A study by Maglio, another researcher, has found that the conscious pursuit of happiness may
backfire ? it?s very difficult to feel that you?ve reached maximum happiness. Happiness really is
like a timid animal. And once you stop chasing it, you might just find that it appears naturally of
its own accord.

The manner in which instruction is imparted in our schools and colleges has not changed
much from the 20th century to the 21st century. Much of the knowledge is taught in our schools
and colleges today prepares the student to pass examinations but not to analyse the knowledge
in a context and apply that knowledge to practical problems. No wonder that many of the
information technology firms that go to engineering colleges for campus recruitment find that
90% of the candidates are unfit for jobs.
A noted educator in a Ted talk explained why judging students based on marks obtained in
examinations is amiss. A student who obtains 60% marks in an examination passes out in first
class. He is lauded for his achievement. But he still has a 40% deficit. He compares this situation
to a motor car running with three wheels. To be able to be a truly knowledgeable person, one has
tointernalise the concepts with his already known knowledge, build on them and apply them. If
you know only 40% or 60% of your curriculum, you miss the connections that link you to the
whole, and the 60% knowledge which is partial will be of no use.
A fundamental thing missing from our schools and colleges is the context. A student is taught
knowledge given in the books. But the student has to apply that knowledge in the society or
community in which he lives. How well he communicates his ideas to others, how well he
understands his emotions and emotions of others, to know how human psyche works and how to
work in a team are all paramount to navigate life. These skills are not taught in schools or
colleges.
How to provide a holistic and useful education to the young generation? It has to be through
parental awareness about what their progeny are missing in schools and colleges. Parents and
educationists may do well to note the words of Albert Einstein on the true purpose of education.
?The value of college education is not the learning of many facts but the training of the mind to
think.?

Correct Answer :-
It has not changed much from the 20th century to the 21st century. [Option ID = 41871]
The manner in which instruction is imparted in our schools and colleges has not changed
much from the 20th century to the 21st century. Much of the knowledge is taught in our schools
and colleges today prepares the student to pass examinations but not to analyse the knowledge
in a context and apply that knowledge to practical problems. No wonder that many of the
information technology firms that go to engineering colleges for campus recruitment find that
90% of the candidates are unfit for jobs.
A noted educator in a Ted talk explained why judging students based on marks obtained in
examinations is amiss. A student who obtains 60% marks in an examination passes out in first
class. He is lauded for his achievement. But he still has a 40% deficit. He compares this situation
to a motor car running with three wheels. To be able to be a truly knowledgeable person, one has
tointernalise the concepts with his already known knowledge, build on them and apply them. If
1)
you know only 40% or 60% of your curriculum, you miss the connections that link you to the
whole, and the 60% knowledge which is partial will be of no use.
A fundamental thing missing from our schools and colleges is the context. A student is taught
knowledge given in the books. But the student has to apply that knowledge in the society or
community in which he lives. How well he communicates his ideas to others, how well he
understands his emotions and emotions of others, to know how human psyche works and how to
work in a team are all paramount to navigate life. These skills are not taught in schools or
colleges.
How to provide a holistic and useful education to the young generation? It has to be through
parental awareness about what their progeny are missing in schools and colleges. Parents and
educationists may do well to note the words of Albert Einstein on the true purpose of education.
?The value of college education is not the learning of many facts but the training of the mind to
think.?
What does ?If you know only 40% or 60% of your curriculum, you miss the connections that link
you to the whole? mean?

If vegetarianism is adopted by 2050, it would stave off about 7 million deaths per year, while
veganism would knock that estimate up to 8 million, thanks largely to a lessening of coronary
heart disease, diabetes, stroke and some cancers.
Experts suggest that food production accounts for one-quarter to one-third of all anthropogenic
greenhouse gas emissions worldwide, most of it because of the livestock industry. ?But just
eating a little less meat right now might make things a whole lot better for our children and
grandchildren.? ?When looking at what would be in line with avoiding dangerous levels of
climate change, we found that you could only stabilise the ratio of food-related emissions to all
emissions if everyone adopted a plant-based diet,? Springmann, a scientist, says. ?That scenario

future.? Research indicates that if everyone became vegetarian by 2050? largely thanks to the
elimination of red meat ? food-related emissions would drop by about 60%. With veganism
instead, emission declines would be around 70%.
Should we all go vegetarian, ideally we would dedicate at least 80% of that pastureland to the

?Happiness is the consequence of personal effort. You fight for it, strive for it, insist upon it, and
sometimes even travel around the world looking for it,? writes Elizabeth Gilbert. ?You have to
participate relentlessly in the manifestations of your own blessings. And once you have achieved
a state of happiness, you must make a mighty effort to keep swimming upward into that
happiness forever, to stay afloat on top of it. If you don?t, you will leak away your innate
contentment.?
However, the latest scientific research suggests that such an attitude can also seriously backfire
for many people ? leading, for instance, to feelings of stress, loneliness, and personal failure.
According to this view, happiness is best seen as kind of timid bird: the harder you strive to catch

Passage I
?Happiness is the consequence of personal effort. You fight for it, strive for it, insist upon it, and
sometimes even travel around the world looking for it,? writes Elizabeth Gilbert. ?You have to
participate relentlessly in the manifestations of your own blessings. And once you have achieved
a state of happiness, you must make a mighty effort to keep swimming upward into that
happiness forever, to stay afloat on top of it. If you don?t, you will leak away your innate
contentment.?
However, the latest scientific research suggests that such an attitude can also seriously backfire
for many people ? leading, for instance, to feelings of stress, loneliness, and personal failure.

The manner in which instruction is imparted in our schools and colleges has not changed
much from the 20th century to the 21st century. Much of the knowledge is taught in our schools
and colleges today prepares the student to pass examinations but not to analyse the knowledge
in a context and apply that knowledge to practical problems. No wonder that many of the
information technology firms that go to engineering colleges for campus recruitment find that
90% of the candidates are unfit for jobs.
A noted educator in a Ted talk explained why judging students based on marks obtained in
examinations is amiss. A student who obtains 60% marks in an examination passes out in first
class. He is lauded for his achievement. But he still has a 40% deficit. He compares this situation
to a motor car running with three wheels. To be able to be a truly knowledgeable person, one has
tointernalise the concepts with his already known knowledge, build on them and apply them. If
you know only 40% or 60% of your curriculum, you miss the connections that link you to the
whole, and the 60% knowledge which is partial will be of no use.
A fundamental thing missing from our schools and colleges is the context. A student is taught
knowledge given in the books. But the student has to apply that knowledge in the society or
community in which he lives. How well he communicates his ideas to others, how well he
understands his emotions and emotions of others, to know how human psyche works and how to
work in a team are all paramount to navigate life. These skills are not taught in schools or
colleges.
How to provide a holistic and useful education to the young generation? It has to be through
parental awareness about what their progeny are missing in schools and colleges. Parents and
educationists may do well to note the words of Albert Einstein on the true purpose of education.
?The value of college education is not the learning of many facts but the training of the mind to
think.?

People become vegetarians for a variety of reasons. Some do it to alleviate animal suffering,
others because they want to pursue a healthier lifestyle. Still others are fans of sustainability or
2)
wish to reduce greenhouse gas emissions.
If vegetarianism is adopted by 2050, it would stave off about 7 million deaths per year, while
veganism would knock that estimate up to 8 million, thanks largely to a lessening of coronary
heart disease, diabetes, stroke and some cancers.
Experts suggest that food production accounts for one-quarter to one-third of all anthropogenic
greenhouse gas emissions worldwide, most of it because of the livestock industry. ?But just
eating a little less meat right now might make things a whole lot better for our children and
grandchildren.? ?When looking at what would be in line with avoiding dangerous levels of
climate change, we found that you could only stabilise the ratio of food-related emissions to all
emissions if everyone adopted a plant-based diet,? Springmann, a scientist, says. ?That scenario
is not very realistic ? but it highlights the importance that food-related emissions will play in the
future.? Research indicates that if everyone became vegetarian by 2050? largely thanks to the
elimination of red meat ? food-related emissions would drop by about 60%. With veganism
instead, emission declines would be around 70%.
Should we all go vegetarian, ideally we would dedicate at least 80% of that pastureland to the
restoration of grasslands and forests, which would capture carbon and further alleviate climate
change. Of course, people formerly engaged in the livestock industry would also need assistance
transitioning to a new career. Even those whose entire livelihoods do not depend on livestock
would stand to suffer. Meat is an important part of history, tradition and cultural identity. ?The
cultural impact of completely giving up meat would be very big, which is why efforts to reduce
meat consumption have often faltered,? are researcher says.
Solution: moderation in meat-eating?s frequency and portion.
In fact, clear solutions already exist for reducing greenhouse gas emissions from the livestock
industry. What is lacking is the will to implement those changes.

?Happiness is the consequence of personal effort. You fight for it, strive for it, insist upon it, and
sometimes even travel around the world looking for it,? writes Elizabeth Gilbert. ?You have to
participate relentlessly in the manifestations of your own blessings. And once you have achieved
a state of happiness, you must make a mighty effort to keep swimming upward into that
happiness forever, to stay afloat on top of it. If you don?t, you will leak away your innate
contentment.?
However, the latest scientific research suggests that such an attitude can also seriously backfire
for many people ? leading, for instance, to feelings of stress, loneliness, and personal failure.
According to this view, happiness is best seen as kind of timid bird: the harder you strive to catch
it, the further it flies away.
These findings help to explain the familiar stress and disappointment that some feel during
special events such as their birthday, Christmas or New Year?s Eve, or a wedding: the more you
wanted to enjoy every last moment, the less fun it became, whereas an unexpectedly good trip
somewhere nearby may have been a far more positive experience.
?once you stop chasing it, you might just find that it appears naturally of its own accord? means
that, Iris Mauss, a U.S. psychologist?s research has since shown that the desire for (and pursuit
of) happiness can also increase feelings of loneliness and disconnection, perhaps because it
causes you to focus your attention on yourself and your own feelings rather than appreciating
5)
the people around you. ?Self-focus might make me engage with other people less, and I might
judge other people more negatively if I perceive them to ?mess? with my happiness,? Mauss says.
?People might set very high standards for their own happiness as a function of this ? they may
think they should be happy all the time, or extremely happy, and that can set people up to feel
disappointed with themselves, that they fall short ? and that could have these self-defeating
effects.?
A study by Maglio, another researcher, has found that the conscious pursuit of happiness may
backfire ? it?s very difficult to feel that you?ve reached maximum happiness. Happiness really is
like a timid animal. And once you stop chasing it, you might just find that it appears naturally of
its own accord.

The manner in which instruction is imparted in our schools and colleges has not changed
much from the 20th century to the 21st century. Much of the knowledge is taught in our schools
and colleges today prepares the student to pass examinations but not to analyse the knowledge
in a context and apply that knowledge to practical problems. No wonder that many of the
information technology firms that go to engineering colleges for campus recruitment find that
90% of the candidates are unfit for jobs.
A noted educator in a Ted talk explained why judging students based on marks obtained in
examinations is amiss. A student who obtains 60% marks in an examination passes out in first
class. He is lauded for his achievement. But he still has a 40% deficit. He compares this situation
to a motor car running with three wheels. To be able to be a truly knowledgeable person, one has
tointernalise the concepts with his already known knowledge, build on them and apply them. If
you know only 40% or 60% of your curriculum, you miss the connections that link you to the
whole, and the 60% knowledge which is partial will be of no use.
A fundamental thing missing from our schools and colleges is the context. A student is taught
knowledge given in the books. But the student has to apply that knowledge in the society or
community in which he lives. How well he communicates his ideas to others, how well he
understands his emotions and emotions of others, to know how human psyche works and how to
work in a team are all paramount to navigate life. These skills are not taught in schools or
colleges.
How to provide a holistic and useful education to the young generation? It has to be through
parental awareness about what their progeny are missing in schools and colleges. Parents and
educationists may do well to note the words of Albert Einstein on the true purpose of education.
?The value of college education is not the learning of many facts but the training of the mind to
think.?

It has not changed much from the 20th century to the 21st century. [Option ID = 41871]
The manner in which instruction is imparted in our schools and colleges has not changed
much from the 20th century to the 21st century. Much of the knowledge is taught in our schools
and colleges today prepares the student to pass examinations but not to analyse the knowledge
in a context and apply that knowledge to practical problems. No wonder that many of the
information technology firms that go to engineering colleges for campus recruitment find that
90% of the candidates are unfit for jobs.
A noted educator in a Ted talk explained why judging students based on marks obtained in
examinations is amiss. A student who obtains 60% marks in an examination passes out in first
class. He is lauded for his achievement. But he still has a 40% deficit. He compares this situation
to a motor car running with three wheels. To be able to be a truly knowledgeable person, one has
tointernalise the concepts with his already known knowledge, build on them and apply them. If
1)
you know only 40% or 60% of your curriculum, you miss the connections that link you to the
whole, and the 60% knowledge which is partial will be of no use.
A fundamental thing missing from our schools and colleges is the context. A student is taught
knowledge given in the books. But the student has to apply that knowledge in the society or
community in which he lives. How well he communicates his ideas to others, how well he
understands his emotions and emotions of others, to know how human psyche works and how to
work in a team are all paramount to navigate life. These skills are not taught in schools or
colleges.
How to provide a holistic and useful education to the young generation? It has to be through
parental awareness about what their progeny are missing in schools and colleges. Parents and
educationists may do well to note the words of Albert Einstein on the true purpose of education.
?The value of college education is not the learning of many facts but the training of the mind to
think.?
What does ?If you know only 40% or 60% of your curriculum, you miss the connections that link
you to the whole? mean?
