11. An experiment was done in which human subjects recognize a pattern within a matrix of abstract designs and then select another design that completes that pattern. The results of the experiment were surprising. The lowest expenditure of energy in neurons in the brain was found in those subjects who performed most successfully in the experiments. Which of the following hypotheses best accounts for the findings of the experiment? (A) The neurons of the brain react less when a subject is trying to recognize patterns than when the subject is doing other kinds of reasoning. (B) Those who performed best in the experiment experienced more satisfaction when working with abstract patterns than did those who performed less well. (C) People who are better at abstract pattern recognition have more energy-efficient neural connections. (D) The energy expenditure of the subjects brains increases when a design that completes the initially recognized pattern is determined. (E) The task of completing a given design is more capably performed by athletes, whose energy expenditure is lower when they are at rest than is that of the general population. 答案C。为什么呢?题目说The lowest expenditure of energy in neurons was found in most successfully in the experiments.而C说better at abstract pattern recognition have more energy-efficient neural connections.那不是矛盾的吗?我觉得是E? 请问为什么E不对呢?
12. A researcher studying drug addicts found that, on average, they tend to manipulate other people a great deal more than nonaddicts do. The researcher concluded that people who frequently manipulate other people are likely to become addicts. Which of the following, if true, most seriously weakens the researcher’s conclusion? (A) After becoming addicted to drugs, drug addicts learn to manipulate other people as a way of obtaining drugs. (B) When they are imprisoned, drug addicts often use their ability to manipulate other people to obtain better living conditions. (C) Some nonaddicts manipulate other people more than some addicts do. (D) People who are likely to become addicts exhibit unusual behavior patterns other than frequent manipulation of other people. (E) The addicts that the researcher studied were often unsuccessful in obtaining what they wanted when they manipulated other people. 答案A。请问为什么C不对呢? C不是反对了原文drug addicts tend to manipulate other people a great deal more than nonaddicts do.吗?
