标题: 有人能帮忙解释一下这道题吗
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

这题要说出来可真不大好说
导致一个结果可能有几个原因，也可能只有一个原因
如果只有一个原因呢，那么people的推测就是对的
而如果有几个原因呢，那就是错的
但是事先并不知道这件事到底会有几个必要条件，所以无法判断出people的对错
也就是d中所说，如果people是错的，那就必须假设admits of more than one interpretation
你再想想吧

前提: action和result同时被预言中且发生了,prediction才是正确的.
结论: 对于同一个result可以有不同的解释.
D说的是:有效的action和无效的action无法区分,而在result发生前一定有很多action发生,所以只要是同时说出了其中一个action和这个result的prediction都是correct的.
举例:我今天吃了猪肉,我今天游了泳,结果我闹肚子了.
prediction1:吃猪肉导致了闹肚子
prediction2:游泳导致了闹肚子
由于它们都发生了,而无法分辨哪个是effective action,所以这两个预言都对.
至于correct and incorrect predication为什么..我没想明白...
(初来逻辑区...还望多指教!)

以下是引用番茄炒蛋在2004-1-17 23:46:00的发言：

为什么如果有几个原因他就是错的?
文中只说了"有action才有result",并没有说"有且仅有action"哦
有点糊涂..

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。
