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

My point of view:'venereal disease'→'commonly ingest mercury', then 'no trace of mercury in his hair'→no 'venereal disease'.
B is the right answer.
HOW ABOUT A?????

a不成立不会影响结论

文章的逻辑是治疗肾病用水银，那么只要发现老贝的头发里有水银，那就一定是因为治疗肾病。那么假定必须是水银不会是因为别的原因进入身体，B就是说人们通常不吃水银，恰好满足了这个要求。而A说，水银进入后就不会出来，这只是一种支持，但不是假设，只能建立摄入水银和身体里有水银之间的联系，而非本题要点。

我也犯了同样的毛病，可惜我觉得我对于assumption和支持不是搞不清楚，就算是题目看清楚了，一下子没有理解进去，通过排除法就把b给排除了，你看文章中说是Since mercury was commonly ingested in Beethoven's time ，b不是和原委中的信息相反吗？而通过a正好可以和文章的推理相关。

实在头疼。。。。不知道weng是怎么整理这类题目的规律的？

btw,你的上船的文件下载了无法打开牙，说要什么磁盘插入的，麻烦再传一次好么？谢谢

我现在还是先搞清楚明确的逻辑关系然后再作，

当然是先看题啦，有的可以不搞的就不搞了

assumption题型还是喜欢取非作，但是如果结合逻辑关系：who is A, who is B的话正确率还是满高的。

刚作了个全新题1999/12-4，37'33, 错5个

这个结果我个人还算满意吧
