People traditionnally believe that a prediction is correct if the action is taken and the result occurs, but in reality, however, "the result admits more than one interpretation", which means that a certain result may happen when some different actions are taken. Thus, it is difficult to judge if the mentionned result comes from the action predicted.
To support this claim, D is best by saying " Distinguishing a correct prediction and effective action from an incorrect prediction and ineffective action is often impossible."区分正确的预言、行之有效的行为和错误的预言、无效的行为往往是不可能的。

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.
(E) Making a successful prediction requires knowing the facts about the context of that prediction.
我看来看去怎么看不懂D想说明什么
