21. 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.
答案是B  觉得Beethoven ingest mercury和其他人 did not ingest mercury并没有什么联系啊 请NN们赐教！！！

题目里面说， . 因为贝多芬时代的人用m来治疗v疾病，假如专家在贝多芬头发里面找到了m，就说明是v导致是贝多芬失聪。（虽然我们不能找到证据说他一定得了m）。
其实这个推论的基础就是说在只有v病人才用m来治病，其他人是不用的，正如b所说：
(B) Some people in Beethoven’s time did not ingest mercury.
(A) None of the mercury introduced into the body can be eliminated.
身体吸收的m不能被减少，无关。
(B) Some people in Beethoven’s time did not ingest mercury.
(C) Mercury is an effective treatment for venereal disease.
m是v的治疗良方，很具有迷惑性的一项，但是我们本题要找出的是m和人之间的关系，m是否有效就跑题了。
(D) Mercury poisoning can cause deafness in people with venereal disease.
m的毒性能导致v病的人失聪。 也很有迷惑性.如何排除呢？ 这个选项其实只是结论的重复，而且我们要找的是结论成立的基础。所以，排除。
(E) Beethoven suffered from psychological problems of the same severity as Newton’s. 贝多芬和newton一样受到精神疾病困扰。离题太远哩。
请指教~~~~~~~

严重谢谢!!!!!!!!!!!!!!!            
终于想通了 作者提到some people hypothesize that venereal disease caused his deafness. 即论证 v病èBeethoven’s deafness
而文中if researchers find a trace of mercury in his hair, we can conclude that this hypothesis is correct.
B选项在服mercury和得v病之间建起桥梁
不过觉得B选项的Some people 说法不太好 怎么也应该体现出是用mercury来治病的吧
好好的人谁有事没事吃水银玩啊~~~拙见~~~

楼上说的对但是我觉得B不对啊
D已经很好的把V和水银联系在了一起
Mercury poisoning can cause deafness in people with venereal disease
水银的中毒，将伴随着V疾病，而导致人们变成聋子。
B是一个无关选项。
