2.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 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 perdictive strategy is good requires knowing the result of using that strategy through several trials.
D.Distinguishing a correct predition and effective action from an incorrect predition and ineffective action is often impossible.
E.Making a successful prediction requires knowing the facts about the context of that prediction.
ANS .为什么不是B呀??
谢谢大家,麻烦啦~~~
大难题啊，我的理解是这样子的：
原文：
目的--预测“一个结果不会发生除非一个action发生”，那么手段----观察“action发生后，结果发生了”那么预测就算对了（显然逻辑上不严密）
结论--显然以上做法不对，因为一个结果可能有多个解释（也就是不一定要action 发生，即使action不发生，结果也可能由别的因素造成，因此上述手段，要解决他们的目标“判断预测是否正确”，是不对的）下面问加强。
A. Judging the success of an action requires specifying the goal of the action.
评判一个行动是否成功，需要清晰行动的目标，与文章推理无关
B. Judging which action to take after a prediction is made requires knowing about other actions that have been successful in similar past situations.
在一个预测作出后，判断采取哪个行动需要知道，其他因素在相似情形下成功的，很混淆，但是即使知道其他行动，并影响了采取什么行动来验证预测，又有什么用呢？
C.Learning whether a certain perdictive strategy is good requires knowing the result of using that strategy through several trials.
学习一个预测是否正确，要知道在多个实验中使用这个策略的结果，这个也无关
D.Distinguishing a correct predition and effective action from an incorrect predition and ineffective action is often impossible.
分辨一个正确的预测和有效的行动，和一个不正确的预测和无效的行动，经常是无效的（做不到的），这句话就是将原文的意思再说了一次，原文说那种方式不行，这里归纳说，
基本做不到，就是有这个目标，用什么办法都可能做不到，这是支持的，但是支持的力度强了一些
E.Making a successful prediction requires knowing the facts about the context of that prediction.
做一个成功的预测需要知道对这个预测的相关上下文细节，与推理无关
这题过于抽象，难度极大，我认为不应该是GMAT的，在LSAT中都属于非常难的 |
