标题: 请教狒狒CR中的第21题！

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.

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

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

答案是B, why?

如果所有人都吃水银的话（听着好吓人的说），

那就不是水银造成的了。

就好像吸毒不是由于喝水引起的一样的道理。
