9. Every action has consequences and among the consequences of any action are other actions. And knowing whether an action is good requires knowing whether its consequences are good, but we cannot know the future, so good actions are impossible.

Which of the following is an assumption on which the argument depends?

(A) Some actions have only other actions as consequences.

(B) We can know that past actions were good.

(C) To know that an action is good requires knowing that retaining from performing it is bad.

(D) Only actions can be the consequences of other actions.

(E) For an action to be good we must be able to know that it is good.

想问一下stimulus第一句话是什么意思？和后文有何关系？

明白了，这样逻辑主线就比较清楚了，虽然还是有点说废话之嫌，但总不失严谨

lawyer，你告诉我last逻辑是非常严谨的，不会有一句和原文推理没有关系的话哦！
