逻辑10套练习一第4题 求教

crona

A thorough search of Edgar Allan Poe's correspon-
dence 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 mor-
phine 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 actu-
ally knew Poe.
(C) Poe's income from writing would not have been  
sufficient to support a morphine addiction.
(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 pre-
vented Poe from indicating in his correspon-
dence that he was addicted to morphine.


答案：E。
我看了网上的解释 如下：“E.对后果的害怕本不会阻止P在通信中表明自己对吗啡上瘾

E最合理，假如说P知道如果在通信中写自己吸吗啡的后果的话，就不敢写了，所以要能通信中知道真实情况，必须排除这种情况，因此，E是对的。”

可是我仍然没看懂。

我把E答案简化（去掉not 与prevent）后是：对吗啡上瘾后果的害怕，就会在correspondence里表明对吗啡上瘾。对吗啡上瘾的害怕说明 吗啡上瘾， 是这样吗？ 因此E就是原观点的逆否。  感觉还是有点别扭，请大家说说自己的看法吧！

这个意思是说对吸食吗啡的后果的害怕不会阻止他在回信中说自己对吗啡上瘾，也就是说如果这前提是真的，那么他的回信里面没有一封提到自己吸食吗啡这个信息是真实的，否则就不是
