Instructions (Q 7-Q 16): Read the following passage carefully and answer the questions given below it.
“Life is not just party and pleasure; it is also pain and despair. Unthinkable things happen. Sometimes everything turns upside down. Bad things happen to good people. Some things are beyond control, such as physical disability and birth defects. We cannot choose our parents or the circumstances of our birth. So if the ball bounced that way, sorry. But what do we do from here; cry or take the ball and run? That is a choice we have to make. On a clear day, there are hundreds of boats sailing in all different directions in a lake. How come? Even though the wind is blowing in one direction, the sailboats are going in different directions. What is the difference? It depends on the way the sail is set, and that is determined by the sailor. The same is true of our lives. We can't choose the direction of the wind, but we can choose how we set the sail. We can choose our attitude even though we cannot always choose our circumstances. The choice is either to act like a victor or a victim. It is not our position but our disposition that determines our destiny. It takes both rain and sunshine to create a rainbow. Our lives are no different. There is happiness and sorrow. There is the good and the bad; dark and bright spots. If we can handle adversity, it only strengthens us. We cannot control all the events that happen in our lives, but we can control how we deal with them. Richard Blechnyden wanted to promote Indian tea at the St. Louis World fair in 1904. It was very hot and no one wanted to sample his tea. Blechnyden saw that all the other iced drinks were doing flourishing business. It dawned on him to make his tea into an iced drink, mix in sugar and sell it. He did and people loved it. That was the introduction of iced tea to the world. When things go wrong, as they sometimes will, we can react responsibly or resentfully. Human beings are not like an action which has no choice. An action cannot decide whether to become a giant tree or to become food for the squirrels. Human beings have choices. If nature gives us a lemon, we have a choice: either cry or make lemonade.”

“The big difference between the ideas of Aristotle and those of Galileo and Newton is that Aristotle believed in a preferred state of rest, which any body would take up if it were not driven by some force or impulse. In particular, he thought that the earth was at rest. But it follows from Newton’s laws that there is no unique standard of rest. One could equally well say that body A was at rest and body B was moving at constant speed with respect to body A, or that body B was at rest and body A was moving. For example, if one sets aside for a moment the rotation of the earth and its orbit round the sun, one could say that the earth was at rest and that a train on it was travelling north at ninety miles per hour or that the train was at rest and the earth was moving south at ninety miles per hour. If one carried out experiments with moving bodies on the train, all Newton’s laws would still hold. For instance, playing Ping-pong on the train, one would find that the ball obeyed Newton’s laws just like a ball on a table by the track. So there is no way to tell whether it is the train or the earth that is moving.

The lack of an absolute standard of rest meant that one could not determine whether two events that took place at different times occurred in the same position in space. For example, suppose our Ping-Pong ball on the train bounces straight up and down. Hitting the table twice on the same spot one second apart. To someone on the track, the two bounces would seem to take place about forty meters apart, because the train wood have traveled that far down the track between the bounces. The nonexistence of absolute rest therefore meant that one could not give an event an absolute position in space, as Aristotle had believed. The position of events and the distance between them would be different far a person of the train and one on he track, and there would be no reason to prefer one person’s position to the other’s.

Newton was very worried by this lack of absolute position, or absolute space, as it was called, because it did not accord with his idea of an absolute God. In fact, he refused to accept lack of absolute space, even though it was implied by his laws. He was severely criticized for this irrational belief by many people, most notably by Bishop Berkeley, a philosopher who believed that all material objects and space and time are an illusion. When the famous Dr. Johnson was told of Brekeley’s opinion, he cried, “I refute it thus!” and stubbed his toe on a large stone.
Both Aristotle and Newton believed in absolute time. That is, they believed that one could unambiguously measure the interval of time between two events, and that this time would be the same whoever measured it, provided they used a good clock. Time was completely separate from and independent of space. This is what most people would take to be the commonsense view. However, we have had to change our ideas about space and time. Although our apparently commonsense nations work well when dealing with things like apples, or planets that travels comparatively slowly, they don’t work at all things moving at or near the speed of light.”

Comprehension

Instructions (Q 7-17): Read the following passage carefully and answer the questions given below it.
”If we are so contemptibly selfish that we can’t radiate a little happiness and pass on a bit of honest appreciation without trying to get something out of the other person in return-if our souls are no bigger than sour crab aples, we shall meet with the failure we so richly deserve. Oh yes, I did want something out of that chap. I wanted something priceless. And I got it. I got the feeling that I had done something for him without his being able to do anything whatever in return for me. That is a feeling that flows and sings in your memory lung after incident is past.
There is a one all-important law of human conduct. If we obey that law, we shall almost never get into trouble. In fact, that law, if obeyed, will bring us countless friends and constant happiness. But the very instant we break the law, we shall get into endless trouble. The law is the: Always make the other person feel important.John Dewey, as we have already noted, said that the desire to be important is the deepest urge in human nature; and William James said, “The deepest principle in human nature is the craving to be appreciated.” As I have already pointed out, it is this urge that differentiates us from the animals. It is this urge that has been responsible for civilization itself.
Philosphers have been speculating on the rules of human relationships for thousands of years, and out of all that speculation, there has evolved only one important precept. It is not new. It is as old history. Zoroaster taught it to his followers in Persia twenty-five hundred years ago. Confucius preached it in China twenty-four centuries ago. Lao-tse, the founder of Taoism, taught it to his disciples in the Valley of the Han. Buddha preached it on the bank of the Holy Ganges five hundred years before Christ. The sacred books of Hinduism taught it a thousand years before that. Jesus taught it among the stony hills of Judea nineteen centuries ago. Jesus summed it up in one thought-probably the most important rule in the World: “Do unto others as you would have others do unto you.”
You want the approval of those with whom you come in contact. You want recognition of your true worth. You want a feeling that you are important in your little world. You don’t want to listen to cheap, insincere flattery, but you do crave sincere appreciation. You want your friends and associates to be, as Charles Schwab put it, “hearty in their approbation and lavish in their praise.” All of us want that.”

7. According to the author, when do human being become extremely selfish?

Instructions (Q 59-69): Read the following passage carefully and answer the questions given below it.

“I discovered, from the analysis of over 25,000 people,that men who succeed in an outstanding way, seldom do so before the age of forty, and more often they do not strike their real pace until they are well beyond the age of fifty, This fact was so astounding that it prompted me to go in to the study of its cause most carefully, carrying the investigation over a period of more than twelve years.
This study disclosed the fact that the major reason why the majority of men who succeed do not begin to do so before the age of fourty to fifty, is their tendency to DISSIPATE their energies through over indulgence in physical expression of the emotion of sex. The majority of men never learn that the urge of sex has other possibilities, which for transcend in importance, that of mere physical expression. The majority of those who make this discovery, do so after having wasted many years at a period when the sex energy is at its height, prior to the age of fourty-five to fifty.This usually is followed by noteworthy achievement.
The lives of many men up to, and sometimes well past the age of fourty, reflect a continued dissipation of energies, which could have been more profitably turned into better channels.Their finer and more powerful emotions are sown wildly to the four winds.Out of this habit of the male, grew the term, “sowing his wild oats.”
The desire for sexual expression is by far the strongest and most impelling of all the human emotions, and for this very reason this desire, when harnessed and transmutted in to action, other than that of physical expression, many raise one to the status of a genius.
One of America’s most able business men frankly admitted that his attractive secretary was responsible for most of the plans he created.He admitted that her presence lifted him to heights of creative imagination, such as he could experience, under no other stimulus.
One of the most successful men in America owes most of his success to the influence of a very charming young woman, who has served as his source of inspiration for more than twelve years.
Everyone knows the man to whom this reference is made, but not everyone knows the REAL SOURCE of his achievements.”
