Part AText 1 People in the United States are becoming more and more aware of the influence of the automobile on their lives. The automobile has an influence on social life, on the economy, and on the environment. It is particularly its influence on the environment that people are increasingly worrying about. It has become obvious that the automobile contributes to air and noise pollution, traffic congestion, urban decay, and suburban sprawl, and that it has kept mass transit systems from developing. People are not so aware, however, of the relation between the automobile and energy problems. In the past few years the country has had energy problems such as brownouts and blackouts, fuel shortages, rising fuel prices, and bad effects on the environment caused by producing energy and converting it from one form to another. These energy problems are in fact closely related to the automobile. An enormous amount of energy, supplied mainly by petroleum, is required by the automobile. In fact, the automobile is responsible for 25 percent of the total energy consumption in the United States. Gasoline is only part of the energy required. It also take energy to manufacture the automobile in the first place. Then it must be transported to dealers who advertise and sell it, all of which takes energy. Energy is also required to make replacement parts for automobile repair. Once the car is on the road, energy still must go into producing gasoline for it. Oil fields must be discovered. Oil must be pumped to the surface and refined. And think of the energy required annually to build and maintain highways and roads. All together the energy requirements of a car are about 50 percent for gasoline and 50 percent for all these other needs that we have just mentioned. The question is, what can we do about all this What can we do to lower this figure, to conserve energy resources so as to reduce air pollution and help solve both our energy and automobile problems The most important thing we can do is to promote changes in passenger transportation. Bicycles are 22 times as energy-efficient as cars, walking 18 times, buses almost 4 times, and railroads 2.5 times. Only airplanes are less energy-efficient than cars. If we promote such changes, we won’t only conserve energy. We will also reduce the crowding and noise in the cities and we can use land for parks instead of for parking lots. It will take time for such changes to come about. Fortunately the sale of bicycles is increasing. And one thing we can do immediately is to increase the energy-efficiency of cars by using smaller cars and carrying more passengers. These changes that have just been suggested will require other changes in our society too, which some people may resist. It will not be easy to make these changes. But consider the alternatives.

"Intelligence" at best is an assumptive construct--the meaning of the word has never been clear. (61)There is more agreement on the kinds of behavior referred to by the term than there is on how to interpret or classify them. But it is generally agreed that a person of high intelligence is one who can grasp ideas readily, make distinctions, reason logically, and make use of verbal and mathematical symbols in solving problems. An intelligence test is a rough measure of a child’s capacity for learning, particularly for learning the kinds of things required in school. It does not measure character, social adjustment, physical endurance, manual skills, or artistic abilities. It is not supposed to-it was not designed for such purposes. (62)To criticize it for such failure is roughly comparable to criticizing a thermometer for not measuring wind velocity.The other thing we have to notice is that the assessment of the intelligence of any subject is essentially a comparative affair.(63) Now since the assessment of intelligence is a comparative matter we must be sure that the scale with which we are comparing our subjects provides a "valid" or "fair" comparison. It is here that some of the difficulties which interest us begin. Any test performed involves at least three factors: the intention to do one’s best, the knowledge required for understanding what you have to do, and the intellectual ability to do it. (64) The first two must be equal for all who are being compared, if any comparison in terms of intelligence is to be made. In school populations in our culture these assumptions can be made fair and reasonable, and the value of intelligence testing has been proved thoroughly. Its value lies, of course, in its providing a satisfactory basis for prediction. No one is in the least interested in the marks a little child gets on his test; what we are interested in is whether we can conclude from his mark on the test that the little child will do better or worse than other children of his age at tasks which we think require" general intelligence". (65)On the whole such a conclusion can be draw with a certain degree of confidence, but only if the child can be assumed to have had the same attitude towards the test as the other with whom he is being compared, and only if he was not punished by lack of relevant information which they possess. The first two must be equal for all who are being compared, if any comparison in terms of intelligence is to be made.

Text 2 Years of watching and comparing bright children and those not bright, or less bright, have shown that they are very different kinds of people. The bright child is curious about life and reality, eager to get in touch with it, embrace it, unite himself with it. There is no wall, no barrier between him and life. The dull child is far less curious, far less interested in what goes on and what is real, more inclined to live in worlds of fantasy. The bright child likes to experiment, to try things out. He lives by the maxim that there is more than one way to skin a cat. If he can’t do something one way, he’ll try another. The dull child is usually afraid to try at all. It takes a good deal of urging to get him to try even once; if that try fails, he is through. The bright child is patient. He can tolerate uncertainty and failure, and will keep trying until he gets an answer. When all his experiments fail, he can even admit to himself and others that for the time being he is not going to get an answer. This may annoy him, but he can wait. Very often, he does not want to be told how to do the problem or solve the puzzle he has struggled with, because he does not want to be cheated out of the chance to figure it out for himself in the future. Not so the dull child. He cannot stand uncertainty or failure. To him, an unanswered question is not a challenge or an opportunity, but a threat. If he can’t find the answer quickly, it must be given to him, and quickly; and he must have answers for everything. Such are the children of whom a second-grade teacher once said, "But my children like to have questions for which there is only one answer." They did; and by a mysterious coincidence, so did she. The bright child is willing to go ahead on the basis of incomplete understanding and information. He will take risks, sail uncharted seas, explore when the landscape is dim, the landmarks few, the light poor. To give only one example, he will often read books he does not understand in the hope that after a while enough understanding will emerge to make it worthwhile to go on. In this spirit some of my fifth graders tried to read Moby Dick. But the dull child will go ahead only when he thinks he knows exactly where he stands and exactly what is ahead of him. If he does not feel he knows exactly what an experience will be like, and if it will not be exactly like other experiences he already knows, he wants no part of it. For while the bright child feels that the universe is, on the whole, a sensible, reasonable, and trustworthy place, the dull child feels that it is senseless, unpredictable, and treacherous. He feels that he can never tell what may happen, particularly in a new situation, except that it will probably be bad. According to the author, the reason why some fifth grade students want to read "Moby Dick" is probably that ______ .
