20.   When people predict that 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 true, 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 using that strategy through several trials.

(D) Distinguishing a correct prediction and effective action from an incorrect prediction and ineffective action is often impossible.（D）

(E) Making a successful prediction requires knowing the facts about the context of that prediction.

supports the claims 就是支持it often becomes clear that the result admits of more than one interpretation。

注意however，必然与其之前之推理或结论有矛盾之处。所以，你要做的就是支持割断之前的推理即可。

楼主，麻烦改下标题，写明题目出处和题号，好吗？

从出题思路看,不是GMAT题.可能是LSAT的东东.
