标题: 想了半个小时也没法说服自己B就是正确答案 [打印本页] 作者: elusive 时间: 2016-4-10 14:53 标题: 想了半个小时也没法说服自己B就是正确答案 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. 作者: elusive 时间: 2016-4-10 14:54

有些人怀疑性病导致耳聋。
因：水印用来治疗性病，
果：如果头发中有水印，那么就是性病导致的耳聋。
另外：这题是一个果因推理，不是因果推理。根据“现象”去猜测“现象”的成因，都是果因推理。注意“果”和“因”发生的时间哪个在前哪个在后。
果：researchers find a trace of mercury in his hair＋ mercury was commonly ingested in Beethoven’s time to treat venereal disease
因：venereal disease caused his deafness
