Identical twins tend to have similar personalities: if environment outweights heredity in personality development, twins raised together should presumably have more similar personalities than those raised apart.A recent study of identical twins through a questionnaire, and concluded that 7 of the 11 are primarily products of heredity. Which of the following, if established, would cast the most doubt on the study's results?

A. Fewer than half of the pairs of twins studied were raised separately.
B. The ages of all of the twins studied fell within a 10 year range.
C. Some of traits that the study attributed to heredity developed in the separately raised twins because those pairs all grew up in similar families.
D. Although over half the traits measured were determined to be linked to heredity, the nature of those traits varied widely.
E. The 11 traits that were measured constitute a representative sample of a larger, genarally accepted pool of key personality traits.

新东方答案是C,但我觉得A也可以。

286。
When people predict that a certain result will not take place unless a certain action is taken, they believe that they have learned that the prediction is correct when the action is taken and the result occurs. On reflection, however, it often becomes clear that the result admits of more than one interpretation.

Which of the following, if ture, best supports the claims above?
A. Judging the success of an action requires specifying the goal of the action.
B. Judging which action to take after a prediction is made requires knowing about other actions that have been successful in similar past situations.
C. Learning whether a certain predictive strategy is good requires knowing the result of using that strategy through several trials.
D. Distinguishing a correct prediction and effective action from an incorrect prediction and ineffective action is often impossible.
E. Making a successful prediction requires knowing the facts about the context of that prediction.

新东方答案是D,没想通。其实题目和选项也没看懂。望哪位牛人解释一下。谢谢！

285、11-7=4 < half of 11.
286. the main idea of the passage is " it often becomes clear that the result admits of more than one interpretation". that is, a same result can be a bad result, a good result, or a part good result. All the interpretations are based on how the predictors interpretate them. Therefore, we can never efficiently point out whether one person's prediction  is right or is wrong.

action taken + result occurs => whether or not prediction is correct. => the result admits of more than one prediction .

Distinguishing a correct prediction and effective action from an incorrect prediction and ineffective action is often impossible. 来搭桥。
