标题: 这道题晕哪,看不懂

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, if often becomes clear that the result admits of more than one interpretation.

Which of the following, if true, best supports the claims abouve?

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 sityations.

c.learing whether a certain predictive strategy is good requires knowing the result of using that strategy through several trials.

d,distinguishing a correct prediciton 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.

correct answer: d

这道题是说: 人们预测当B没有发生是因为A没有发生时就认为已经学会了预测=当A发生时B一定会发生,但其实第一个结论有不同的解释。

这说明不能从一个"没A就没B"的结论下而断定“有了A就有B”。

D 就是这个意思。
