11. The situation has gotten worse. Unless Elizabeth goes I must go. But she will not to if I stay So we will both have to go. What is the flaw in the reasoning above? (A) The first claim, that the situation has gotten worse, is irrelevant. (B) A possible course of action is overlooked (C) It is assumed that staying is the same as not going. (D) The conclusion refers to a possibility that is not explicitly referred to in any of the premises. (E) Insufficient information is given about the circumstances.

这里我选了ｅ我明白ｂ对但是我觉得因为证据和结论之间是需要加一些条件才能达到的，所以我觉得ｅ没有错，有人和我说为什么ｅ错么？

原文有两个关系：1。I stay---->E goes。2。I stay---->E not goes。从1，2可以看出I must go。否则1，2会得出矛盾的结果。对于E，可以go 也可以not go。所以B对。也即Information是充分的，只是结果应该有两种，不是一种。故E错
