Directions: Read the passage and answer the following question.

Much of Kelly’s thinking, including his view on science, is based on the philosophical position of constructive alternatives. According to this position, there is no objective reality or absolute truth to discover, instead, there are efforts to construe events–to interpret phenomena in order to make sense of them. There are always alternative constructions available from which to choose. This is true for the scientists as it is for people who behave as scientists. In Kelly's view the scientific enterprise is not the discovery of truth or, as Freud might have suggested, the uncovering of things previously hidden in the mind. Rather the scientific enterprise is the effort to develop construct systems that are useful in anticipating events.
Kelly was concerned about the tendency toward dogma in psychology. Psychologists believed that constructs of inner states and traits actually existed rather than understanding them as "things" in a theoretician's head. If someone is described as an introvert, we tend to check whether he is an introvert, rather than checking the person who is responsible for the statement. Kelly's position against "truth" and dogma is of considerable significance. It leads, for instance, to the view that subjective thinking is an essential step in the scientific process. Subjective thinking allows one to establish the "invitation mood" in which one is free to invite many alternative interpretations of phenomena, and to entertain propositions that, initially, may seem absurd. The invitational mood is a necessary part of the exploration of the world, for the professional scientist as well as for the patient in therapy. It is the mood established by the creative novelist. But where a novelist publishes his make-believe and may even be unconcerned with the evidence supporting his constructions, a professional scientist tends to minimise the wind of make-believe and to focus on objective evidence.
According to Kelly, it is the freedom to make believe and to establish the invitational mood that allows for the development of hypothesis. A hypothesis should not be asserted as a fact, but instead should allow the scientist to pursue its implications as if it were true. Kelly viewed a theory as a tentative expression of what has been observed and of what is expected. A theory has a range of convenience, indicating the boundaries of phenomena the theory can cover, and a focus of convenience, indicating the points within the boundaries where the theory works best. For example, Freud\\\\\\'s theory has a broad range of convenience and the focus of convenience is the unconscious and abnormal behaviour. Rogers’ theory has a narrower range of convenience and its focus of convenience is more on the concept of the self and the process of change. Different theories have different ranges of convenience and different foci of convenience.
Kelly theories were modifiable and ultimately expendable. A theory is modified or discarded when it stops leading to new predictions or leads to incorrect predictions. Among scientists, as well as among people in general, how long one holds on to a theory in the face of contradictory information is partly a matter of taste and style.
Kelly\\'s view on science is not unique, but is important in terms of its clarity of expression and its points of emphasis. It also has a number of important ramifications. First, since there are no “facts,” and also different theories have different ranges of convenience, we need not argue about whether the facts are "psychological" or "physiological" or whether one theory is right and another wrong – they are different constructions. Second, Kelly's approach involved criticism of an extreme emphasis on measurement. Kelly felt that such an approach can lead to viewing concepts as "things" rather than as representations, and to making a psychologist into a technician rather than a scientist. Third, Kelly's view of science leaves room for the clinical as opposed to the experimental method, which he considered useful because it speaks the language of hypothesis, because it leads to the emergence of new variables and focuses on important questions. The fourth significant thing about Kelly\\'s view of science–it should focus on important issues. In Kelly\\'s belief, many psychologists are afraid of doing anything that might not be recognised as science, and they have given up struggling with important aspects of human behaviour. His suggestion was that they stop trying to be scientific and that they get on with the job of understanding people. Kelly believed that a good scientific theory should encourage the invention of new approaches to the solution of the problems of people and society.

Finally, as noted, Kelly took a firm stand against dogma. It was his contention that many scholars waste time trying to disprove their colleagues' claims to make room for their own explanations. It is a tribute to Kelly's sense of perspective, sense of humour, and lack of defensiveness concerning his own work that he could describe one of his own theoretical papers as involving "half-truths" only, and that he could view his theory as contributing to its downfall. It is this theory–the theory of personal constructs–that we now discuss.

As proposed in the passage, when does magnetic reversal take place?

Directions: Read the following passage and answer the question that follows.

Nothing is sure, but death and taxes, and of course, north is north and south is south, and thus, it has always been so. But, this is what they say, and there is no guarantee that it is the truth. You can believe that death and taxes are for real, but you might want to reconsider the part about south is south and north is north because many times during the history of our planet, north has become south and south has become north. This may sound extraordinarily fictitious, but it is true and a process called magnetic reversal is behind it. 
Paleogeologists have found that this phenomenon is the real thing, in a field study known as paleomagnetism, by investigating rocks. There is a lot that goes on before anything can be deciphered from the rocks. When rocks are being formed from magma, atoms within their crystals respond to Earth’s magnetic field by pointing towards the magnetic North pole of Earth. The magnetic force of attraction is generated by the North Pole on the atoms of rocks. By age dating the rocks and their magnetic alignment, scientists can determine where on Earth the North Pole was located at the time because as the rocks solidified, they trapped information within them. The study of ancient lava flows has shown that at certain periods in Earth’s history, magnetic north was located exactly at the place it is located at the moment.

It has now been determined that this reversal takes place quite regularly, i.e. every 500,000 years. The last reversal is said to have taken place approximately 700,000 years ago. The name given by scientists to the periods “normal” polarity is the magnetic orientation of the era. On the other hand, “reversed” polarity or the magnetic orientation of the reverse situation is called “magnetic chrons”.

Although, the fact of such reversal is clear, the answers to the how and why questions are debatable. Because no one precisely knows how Earth’s magnetic field is produced, it becomes difficult to say how it might be reversed. Among explanations proposed, is a reversal of direction of convection currents in the liquid outer core of the Earth or the collision between Earth and a meteorite or a comet. While the precise effects of reversal are not known, there can be little doubt that Earth would receive a great deal more damaging ultraviolet radiation during the process than it does now. There has also been correlation between such occurrences and the extinction of certain species of animals in the past.

Much of Kelly’s thinking, including his view on science, is based on the philosophical position of constructive alternatives. According to this position, there is no objective reality or absolute truth to discover, instead, there are efforts to construe events–to interpret phenomena in order to make sense of them. There are always alternative constructions available from which to choose. This is true for the scientists as it is for people who behave as scientists. In Kelly's view the scientific enterprise is not the discovery of truth or, as Freud might have suggested, the uncovering of things previously hidden in the mind. Rather the scientific enterprise is the effort to develop construct systems that are useful in anticipating events.
Kelly was concerned about the tendency toward dogma in psychology. Psychologists believed that constructs of inner states and traits actually existed rather than understanding them as "things" in a theoretician's head. If someone is described as an introvert, we tend to check whether he is an introvert, rather than checking the person who is responsible for the statement. Kelly's position against "truth" and dogma is of considerable significance. It leads, for instance, to the view that subjective thinking is an essential step in the scientific process. Subjective thinking allows one to establish the "invitation mood" in which one is free to invite many alternative interpretations of phenomena, and to entertain propositions that, initially, may seem absurd. The invitational mood is a necessary part of the exploration of the world, for the professional scientist as well as for the patient in therapy. It is the mood established by the creative novelist. But where a novelist publishes his make-believe and may even be unconcerned with the evidence supporting his constructions, a professional scientist tends to minimise the wind of make-believe and to focus on objective evidence.
According to Kelly, it is the freedom to make believe and to establish the invitational mood that allows for the development of hypothesis. A hypothesis should not be asserted as a fact, but instead should allow the scientist to pursue its implications as if it were true. Kelly viewed a theory as a tentative expression of what has been observed and of what is expected. A theory has a range of convenience, indicating the boundaries of phenomena the theory can cover, and a focus of convenience, indicating the points within the boundaries where the theory works best. For example, Freud\\\\\\'s theory has a broad range of convenience and the focus of convenience is the unconscious and abnormal behaviour. Rogers’ theory has a narrower range of convenience and its focus of convenience is more on the concept of the self and the process of change. Different theories have different ranges of convenience and different foci of convenience.

Among scientists, as well as among people in general, how long one holds on to a theory in the face of contradictory information is partly a matter of taste and style.
Kelly\\'s view on science is not unique, but is important in terms of its clarity of expression and its points of emphasis. It also has a number of important ramifications. First, since there are no “facts,” and also different theories have different ranges of convenience, we need not argue about whether the facts are "psychological" or "physiological" or whether one theory is right and another wrong – they are different constructions. Second, Kelly's approach involved criticism of an extreme emphasis on measurement. Kelly felt that such an approach can lead to viewing concepts as "things" rather than as representations, and to making a psychologist into a technician rather than a scientist. Third, Kelly's view of science leaves room for the clinical as opposed to the experimental method, which he considered useful because it speaks the language of hypothesis, because it leads to the emergence of new variables and focuses on important questions. The fourth significant thing about Kelly\\'s view of science–it should focus on important issues. In Kelly\\'s belief, many psychologists are afraid of doing anything that might not be recognised as science, and they have given up struggling with important aspects of human behaviour. His suggestion was that they stop trying to be scientific and that they get on with the job of understanding people.

Finally, as noted, Kelly took a firm stand against dogma. It was his contention that many scholars waste time trying to disprove their colleagues' claims to make room for their own explanations.

Directions: Read the passage and answer the following question.

Much of Kelly’s thinking, including his view on science, is based on the philosophical position of constructive alternatives. According to this position, there is no objective reality or absolute truth to discover, instead, there are efforts to construe events–to interpret phenomena in order to make sense of them. There are always alternative constructions available from which to choose. This is true for the scientists as it is for people who behave as scientists. In Kelly's view the scientific enterprise is not the discovery of truth or, as Freud might have suggested, the uncovering of things previously hidden in the mind. Rather the scientific enterprise is the effort to develop construct systems that are useful in anticipating events.
Kelly was concerned about the tendency toward dogma in psychology. Psychologists believed that constructs of inner states and traits actually existed rather than understanding them as "things" in a theoretician's head. If someone is described as an introvert, we tend to check whether he is an introvert, rather than checking the person who is responsible for the statement. Kelly's position against "truth" and dogma is of considerable significance. It leads, for instance, to the view that subjective thinking is an essential step in the scientific process. Subjective thinking allows one to establish the "invitation mood" in which one is free to invite many alternative interpretations of phenomena, and to entertain propositions that, initially, may seem absurd. The invitational mood is a necessary part of the exploration of the world, for the professional scientist as well as for the patient in therapy. It is the mood established by the creative novelist. But where a novelist publishes his make-believe and may even be unconcerned with the evidence supporting his constructions, a professional scientist tends to minimise the wind of make-believe and to focus on objective evidence.
According to Kelly, it is the freedom to make believe and to establish the invitational mood that allows for the development of hypothesis. A hypothesis should not be asserted as a fact, but instead should allow the scientist to pursue its implications as if it were true. Kelly viewed a theory as a tentative expression of what has been observed and of what is expected. A theory has a range of convenience, indicating the boundaries of phenomena the theory can cover, and a focus of convenience, indicating the points within the boundaries where the theory works best. For example, Freud\\\\\\'s theory has a broad range of convenience and the focus of convenience is the unconscious and abnormal behaviour. Rogers’ theory has a narrower range of convenience and its focus of convenience is more on the concept of the self and the process of change. Different theories have different ranges of convenience and different foci of convenience.
Kelly theories were modifiable and ultimately expendable. A theory is modified or discarded when it stops leading to new predictions or leads to incorrect predictions. Among scientists, as well as among people in general, how long one holds on to a theory in the face of contradictory information is partly a matter of taste and style.
Kelly\\'s view on science is not unique, but is important in terms of its clarity of expression and its points of emphasis. It also has a number of important ramifications. First, since there are no “facts,” and also different theories have different ranges of convenience, we need not argue about whether the facts are "psychological" or "physiological" or whether one theory is right and another wrong – they are different constructions. Second, Kelly's approach involved criticism of an extreme emphasis on measurement. Kelly felt that such an approach can lead to viewing concepts as "things" rather than as representations, and to making a psychologist into a technician rather than a scientist. Third, Kelly's view of science leaves room for the clinical as opposed to the experimental method, which he considered useful because it speaks the language of hypothesis, because it leads to the emergence of new variables and focuses on important questions. The fourth significant thing about Kelly\\'s view of science–it should focus on important issues. In Kelly\\'s belief, many psychologists are afraid of doing anything that might not be recognised as science, and they have given up struggling with important aspects of human behaviour. His suggestion was that they stop trying to be scientific and that they get on with the job of understanding people. Kelly believed that a good scientific theory should encourage the invention of new approaches to the solution of the problems of people and society.

Finally, as noted, Kelly took a firm stand against dogma. It was his contention that many scholars waste time trying to disprove their colleagues' claims to make room for their own explanations. It is a tribute to Kelly's sense of perspective, sense of humour, and lack of defensiveness concerning his own work that he could describe one of his own theoretical papers as involving "half-truths" only, and that he could view his theory as contributing to its downfall.

According to the passage, what is the effect of magnetic reversal?

Directions: Read the following passage and answer the question that follows.

Nothing is sure, but death and taxes, and of course, north is north and south is south, and thus, it has always been so. But, this is what they say, and there is no guarantee that it is the truth. You can believe that death and taxes are for real, but you might want to reconsider the part about south is south and north is north because many times during the history of our planet, north has become south and south has become north. This may sound extraordinarily fictitious, but it is true and a process called magnetic reversal is behind it. 
Paleogeologists have found that this phenomenon is the real thing, in a field study known as paleomagnetism, by investigating rocks. There is a lot that goes on before anything can be deciphered from the rocks. When rocks are being formed from magma, atoms within their crystals respond to Earth’s magnetic field by pointing towards the magnetic North pole of Earth. The magnetic force of attraction is generated by the North Pole on the atoms of rocks. By age dating the rocks and their magnetic alignment, scientists can determine where on Earth the North Pole was located at the time because as the rocks solidified, they trapped information within them. The study of ancient lava flows has shown that at certain periods in Earth’s history, magnetic north was located exactly at the place it is located at the moment.

It has now been determined that this reversal takes place quite regularly, i.e. every 500,000 years. The last reversal is said to have taken place approximately 700,000 years ago. The name given by scientists to the periods “normal” polarity is the magnetic orientation of the era. On the other hand, “reversed” polarity or the magnetic orientation of the reverse situation is called “magnetic chrons”.

Although, the fact of such reversal is clear, the answers to the how and why questions are debatable. Because no one precisely knows how Earth’s magnetic field is produced, it becomes difficult to say how it might be reversed. Among explanations proposed, is a reversal of direction of convection currents in the liquid outer core of the Earth or the collision between Earth and a meteorite or a comet. While the precise effects of reversal are not known, there can be little doubt that Earth would receive a great deal more damaging ultraviolet radiation during the process than it does now. There has also been correlation between such occurrences and the extinction of certain species of animals in the past.

The name given by scientists to the periods “normal” polarity is the magnetic orientation of the era. On the other hand, “reversed” polarity or the magnetic orientation of the reverse situation is called “magnetic chrons”.

Although, the fact of such reversal is clear, the answers to the how and why questions are debatable. Because no one precisely knows how Earth’s magnetic field is produced, it becomes difficult to say how it might be reversed. Among explanations proposed, is a reversal of direction of convection currents in the liquid outer core of the Earth or the collision between Earth and a meteorite or a comet. While the precise effects of reversal are not known, there can be little doubt that Earth would receive a great deal more damaging ultraviolet radiation during the process than it does now. There has also been correlation between such occurrences and the extinction of certain species of animals in the past.  

In the passage, how has the extinction of certain species been correlated to magnetic reversal?

Directions: Read the following passage and answer the question that follows.

Nothing is sure, but death and taxes, and of course, north is north and south is south, and thus, it has always been so. But, this is what they say, and there is no guarantee that it is the truth. You can believe that death and taxes are for real, but you might want to reconsider the part about south is south and north is north because many times during the history of our planet, north has become south and south has become north. This may sound extraordinarily fictitious, but it is true and a process called magnetic reversal is behind it. 
Paleogeologists have found that this phenomenon is the real thing, in a field study known as paleomagnetism, by investigating rocks. There is a lot that goes on before anything can be deciphered from the rocks. When rocks are being formed from magma, atoms within their crystals respond to Earth’s magnetic field by pointing towards the magnetic North pole of Earth. The magnetic force of attraction is generated by the North Pole on the atoms of rocks. By age dating the rocks and their magnetic alignment, scientists can determine where on Earth the North Pole was located at the time because as the rocks solidified, they trapped information within them.

Constructive Alternativism implies that

Passage-III

Directions: Read the passage and answer the following question.

Much of Kelly’s thinking, including his view on science, is based on the philosophical position of constructive alternatives. According to this position, there is no objective reality or absolute truth to discover, instead, there are efforts to construe events–to interpret phenomena in order to make sense of them. There are always alternative constructions available from which to choose. This is true for the scientists as it is for people who behave as scientists. In Kelly's view the scientific enterprise is not the discovery of truth or, as Freud might have suggested, the uncovering of things previously hidden in the mind. Rather the scientific enterprise is the effort to develop construct systems that are useful in anticipating events.
Kelly was concerned about the tendency toward dogma in psychology. Psychologists believed that constructs of inner states and traits actually existed rather than understanding them as "things" in a theoretician's head. If someone is described as an introvert, we tend to check whether he is an introvert, rather than checking the person who is responsible for the statement. Kelly's position against "truth" and dogma is of considerable significance. It leads, for instance, to the view that subjective thinking is an essential step in the scientific process. Subjective thinking allows one to establish the "invitation mood" in which one is free to invite many alternative interpretations of phenomena, and to entertain propositions that, initially, may seem absurd. The invitational mood is a necessary part of the exploration of the world, for the professional scientist as well as for the patient in therapy. It is the mood established by the creative novelist. But where a novelist publishes his make-believe and may even be unconcerned with the evidence supporting his constructions, a professional scientist tends to minimise the wind of make-believe and to focus on objective evidence.
According to Kelly, it is the freedom to make believe and to establish the invitational mood that allows for the development of hypothesis. A hypothesis should not be asserted as a fact, but instead should allow the scientist to pursue its implications as if it were true. Kelly viewed a theory as a tentative expression of what has been observed and of what is expected. A theory has a range of convenience, indicating the boundaries of phenomena the theory can cover, and a focus of convenience, indicating the points within the boundaries where the theory works best. For example, Freud\\\\\\'s theory has a broad range of convenience and the focus of convenience is the unconscious and abnormal behaviour. Rogers’ theory has a narrower range of convenience and its focus of convenience is more on the concept of the self and the process of change. Different theories have different ranges of convenience and different foci of convenience.
Kelly theories were modifiable and ultimately expendable. A theory is modified or discarded when it stops leading to new predictions or leads to incorrect predictions. Among scientists, as well as among people in general, how long one holds on to a theory in the face of contradictory information is partly a matter of taste and style.
Kelly\\'s view on science is not unique, but is important in terms of its clarity of expression and its points of emphasis. It also has a number of important ramifications. First, since there are no “facts,” and also different theories have different ranges of convenience, we need not argue about whether the facts are "psychological" or "physiological" or whether one theory is right and another wrong – they are different constructions. Second, Kelly's approach involved criticism of an extreme emphasis on measurement. Kelly felt that such an approach can lead to viewing concepts as "things" rather than as representations, and to making a psychologist into a technician rather than a scientist. Third, Kelly's view of science leaves room for the clinical as opposed to the experimental method, which he considered useful because it speaks the language of hypothesis, because it leads to the emergence of new variables and focuses on important questions. The fourth significant thing about Kelly\\'s view of science–it should focus on important issues. In Kelly\\'s belief, many psychologists are afraid of doing anything that might not be recognised as science, and they have given up struggling with important aspects of human behaviour. His suggestion was that they stop trying to be scientific and that they get on with the job of understanding people. Kelly believed that a good scientific theory should encourage the invention of new approaches to the solution of the problems of people and society.

Finally, as noted, Kelly took a firm stand against dogma. It was his contention that many scholars waste time trying to disprove their colleagues' claims to make room for their own explanations. It is a tribute to Kelly's sense of perspective, sense of humour, and lack of defensiveness concerning his own work that he could describe one of his own theoretical papers as involving "half-truths" only, and that he could view his theory as contributing to its downfall. It is this theory–the theory of personal constructs–that we now discuss.

What does 'fight and flight' refer to in the passage?

Directions: Read the passage and answer the following question.

According to the Journal of American Geriatrics: If an inactive 70-year-old were to begin an exercise programme of 'moderate activity', the result would be a gain of 15 years in his age and if the subject were to achieve the 'athlete' level of conditioning, he could experience a potential improvement of 40 years in his age!
Harvard researchers tracked the workout habits of 17,321 healthy men for over 20 years and found that those who burnt at least 1,500 calories a week in activities such as running, brisk walking, cycling or swimming had a 25 percent lower death rate than men who burnt a meagre 150 calories per week exercising. That's the equivalent of the difference in mortality between non-smokers and men who smoke a pack of cigarettes daily!

Another Harvard study followed the living habits of more than 47,000 men aged 40 to 75 years for six years, and after adjusting for factors like diet and family history found that those who worked out at least thrice a week were significantly less likely to develop colon cancer or polyps (tumorous growth that can be a precursor to cancer) as compared to sedentary men.

Being overweight increases the risk of colon cancer. Obese men have a 50 per cent higher risk of contracting the disease and those who carried extra weight primarily in their abdominal region were 3 ½ times as likely as their leaner subjects. Researchers believe that exercise reduces the risk of colon cancer by lowering insulin levels that tend to be higher in normal weight people who are not physically active. The lower level of insulin promotes bowel activity, which does not allow cancer causing toxins to linger in the body for long.

Exercise reduces the risk of all types of cancer, by significantly boosting our body's internal defense against free radicals. No antioxidant action plan is complete without regular exercise, for the natural endogenous antioxidants (those produced by the human body), such as SOH, GSH and catalase may become too fragile for supplements to have their full effect.

For long, it has been known that exercise reduces blood pressure in the sedentary, helps lessen angina pains, and decreases harmful body fat which would otherwise affect the arteries and the heart. The heart, like any other muscle in the body, gets bigger, stronger and more efficient with exercise and pumps more oxygenated blood to different parts of the body. Not only are nutrients transported throughout the body; the muscles in the body also become more efficient at extracting oxygen from the bloodstream. Circulation improves too, partly because exercise boosts the number of small blood vessels (capillaries) that deliver oxygen to tissues and carry the excess away, including the deadly LDL cholesterol.

Exercise also burns body fat and raises metabolic activity. Most commonly people desirous of burning unwanted calories follow an exercise regime. Exercise helps regulate blood sugar metabolism and therefore may help to ward off the diseases.

Just as exercise strengthens the heart and lungs, bones and muscles, it may also power the brain, leading to faster reflexes, increased alertness and a pervading sense of well-being. Today's Archimedes would find creative inspiration, not in the bath, but on the treadmill. Aerobic exercise increases the amount of certain brain chemicals that stimulate growth of nerve cells. It also triggers the release of several key neurotransmitters, including epinephrine and norepinephrine that are known to boost awareness.

A vigorous workout stimulates the body to pump out the so called stress hormones, such as cortisol and epinephrine that prepare your heart, lungs and muscles for 'fight and flight'. By working out regularly, you almost 'train' the body to react less intensely to stress, as a result of that you can cope better with anxiety provoking events.

How does obesity affect a person's health?

Directions: Read the passage and answer the following question.

According to the Journal of American Geriatrics: If an inactive 70-year-old were to begin an exercise programme of 'moderate activity', the result would be a gain of 15 years in his age and if the subject were to achieve the 'athlete' level of conditioning, he could experience a potential improvement of 40 years in his age!
Harvard researchers tracked the workout habits of 17,321 healthy men for over 20 years and found that those who burnt at least 1,500 calories a week in activities such as running, brisk walking, cycling or swimming had a 25 percent lower death rate than men who burnt a meagre 150 calories per week exercising. That's the equivalent of the difference in mortality between non-smokers and men who smoke a pack of cigarettes daily!

Another Harvard study followed the living habits of more than 47,000 men aged 40 to 75 years for six years, and after adjusting for factors like diet and family history found that those who worked out at least thrice a week were significantly less likely to develop colon cancer or polyps (tumorous growth that can be a precursor to cancer) as compared to sedentary men.

Being overweight increases the risk of colon cancer. Obese men have a 50 per cent higher risk of contracting the disease and those who carried extra weight primarily in their abdominal region were 3 ½ times as likely as their leaner subjects. Researchers believe that exercise reduces the risk of colon cancer by lowering insulin levels that tend to be higher in normal weight people who are not physically active. The lower level of insulin promotes bowel activity, which does not allow cancer causing toxins to linger in the body for long.

Exercise reduces the risk of all types of cancer, by significantly boosting our body's internal defense against free radicals. No antioxidant action plan is complete without regular exercise, for the natural endogenous antioxidants (those produced by the human body), such as SOH, GSH and catalase may become too fragile for supplements to have their full effect.

For long, it has been known that exercise reduces blood pressure in the sedentary, helps lessen angina pains, and decreases harmful body fat which would otherwise affect the arteries and the heart. The heart, like any other muscle in the body, gets bigger, stronger and more efficient with exercise and pumps more oxygenated blood to different parts of the body. Not only are nutrients transported throughout the body; the muscles in the body also become more efficient at extracting oxygen from the bloodstream. Circulation improves too, partly because exercise boosts the number of small blood vessels (capillaries) that deliver oxygen to tissues and carry the excess away, including the deadly LDL cholesterol.

Exercise also burns body fat and raises metabolic activity. Most commonly people desirous of burning unwanted calories follow an exercise regime. Exercise helps regulate blood sugar metabolism and therefore may help to ward off the diseases.

Directions: Read the following passage and answer the question that follows.

Nothing is sure, but death and taxes, and of course, north is north and south is south, and thus, it has always been so. But, this is what they say, and there is no guarantee that it is the truth. You can believe that death and taxes are for real, but you might want to reconsider the part about south is south and north is north because many times during the history of our planet, north has become south and south has become north. This may sound extraordinarily fictitious, but it is true and a process called magnetic reversal is behind it. 
Paleogeologists have found that this phenomenon is the real thing, in a field study known as paleomagnetism, by investigating rocks. There is a lot that goes on before anything can be deciphered from the rocks. When rocks are being formed from magma, atoms within their crystals respond to Earth’s magnetic field by pointing towards the magnetic North pole of Earth. The magnetic force of attraction is generated by the North Pole on the atoms of rocks. By age dating the rocks and their magnetic alignment, scientists can determine where on Earth the North Pole was located at the time because as the rocks solidified, they trapped information within them. The study of ancient lava flows has shown that at certain periods in Earth’s history, magnetic north was located exactly at the place it is located at the moment.

It has now been determined that this reversal takes place quite regularly, i.e. every 500,000 years. The last reversal is said to have taken place approximately 700,000 years ago. The name given by scientists to the periods “normal” polarity is the magnetic orientation of the era. On the other hand, “reversed” polarity or the magnetic orientation of the reverse situation is called “magnetic chrons”.

Although, the fact of such reversal is clear, the answers to the how and why questions are debatable. Because no one precisely knows how Earth’s magnetic field is produced, it becomes difficult to say how it might be reversed. Among explanations proposed, is a reversal of direction of convection currents in the liquid outer core of the Earth or the collision between Earth and a meteorite or a comet. While the precise effects of reversal are not known, there can be little doubt that Earth would receive a great deal more damaging ultraviolet radiation during the process than it does now. There has also been correlation between such occurrences and the extinction of certain species of animals in the past.
