一、把握宗旨

千变万化不离其宗，我们只需要在解题过程中记住：

只要找出能够使推理成立的条件或必要条件，我们就不必保证通过这一条件来推理是正确的。

二、案例

A thorough search of Edgar Allan Poe’s correspondence has turned up not a single letter in which he mentions his reputed morphine addiction. On the basis of this evidence it is safe to say that Poe’s reputation for having been a morphine addict is undeserved and that reports of his supposed addiction are untrue.

Which of the following is assumed by the argument above?

　　(A) Reports claiming that Poe was addicted to morphine did not begin to circulate until after his death.

　　(B) None of the reports of Poe’s supposed morphine addiction can be traced to individuals who actually knew Poe.

　　(D) Poe would have been unable to carry on an extensive correspondence while under the influence of morphine

　　(E) Fear of the consequences would not have prevented Poe from indicating in his correspondence that he was addicted to morphine.

上述题干的关键信息：一、研究发现Poe的信笺里面提到他患有吗啡瘾。二、Poe没有吗啡瘾。

在五个选项当中均给到了不同的假设条件，我们需要通过反推来进行敲定，找出可以让推理成立的假设条件。

考生往往认为除了信件调查这样的证据，还有其他证据可以推出Poe不是咖啡瘾。

一般来说，当一个推理从一个我们已知的事实推断出一个结论时，我们需要记住的是，隐含的假设大多是这个结论的唯一原因。

换句话说，如果我们想在这个问题中解释Poe的信件，那么我们只能假设Poe不会因为害怕后果而在信件中提到对咖啡的兴趣。这个问题的正确假设选项是E.
