标题: 求助FF135 Q21

. Historian: We can learn about the medical history of individuals through chemical analysis of their hair. It is likely, for example, that Isaac Newton’s psychological problems were due to mercury poisoning; traces of mercury were found in his hair. Analysis is now being done on a lock of Beethoven’s hair. Although no convincing argument has shown that Beethoven ever had a venereal disease, some people hypothesize that venereal disease caused his deafness. Since mercury was commonly ingested in Beethoven’s time to treat venereal disease, if researchers find a trace of mercury in his hair, we can conclude that this hypothesis is correct.

Which one of the following is an assumption on which the historian’s argument depends?

A. None of the mercury introduced into the body can be eliminated.

B. Some people in Beethoven’s time did not ingest mercury.

C. Mercury is an effective treatment for venereal disease.

D. Mercury poisoning can cause deafness in people with venereal disease.

E. Beethoven suffered from psychological problems of the same severity as Newton’s.

这题我想不通，为什么要选B，我怎么认为B根本就不能对于结论起到什么作用？

我认为选C。

B对

B的意思是不是所有人都ingest 水银，说明”ingest 水银“在当时是一种“个性”，而非“共性”，

试想想，如果“ingest 水银”是一种“共性”，也就是说所有人都会ingest 水银，那么即使在贝多芬的头发里找到水银，那个hypothesis也不一定对，也就是说，不能依靠水银的存在来推出任何东西。只有在“不是所有人都ingest 水银”这种情况下，那个历史学家的argument才成立。

可是我觉得some不是all的对立面啊，如果只是一些人不ingest的话也没什么用的

C是无关干扰选项，文中只说B用M来治性病，并没说M就有效。就算c取非也削弱不了原文
