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B，实在是不知道为什么，我感觉C选项能更好的将Mercury 和 V-disease连接在一起
22. In 1992, a major newspaper circulated throughout North American paid its reporters an average salary paid by its principle competitors to their reporters. An executive of the newspaper argued that this practice was justified, since any shortfall that might exist in the reporters’ salaries is fully compensated by the valuable training they receive through their assignments.
Which one of the following, if true about the newspaper in 1992, most seriously undermines the justification offered by the executive?
(A) Senior reporters at the newspaper earned as much as reporters of similar stature who worked for the newspaper’s principle competitors.
(B) Most of the newspaper’s reporters had worked there for more than ten years.
(C) The circulation of the newspaper had recently reached a plateau, after it had increased steadily throughout the 1980s.
(D) The union that represented reporters at the newspaper was different from the union that represented reporters at the newspaper’s competitors.
(E) The newspaper was widely read throughout continental Europe and Great Britain as well as North America
.
答案B。 我知道CDE可以很快排除，但是实在看不出B为什么比A好，而且工作了十年能说明什么问题呢？
顺便问一下，听XDF老师说狒狒逻辑题是从LSAT里面来的，那对备考GMAT到底有没有用呢，如果想进行GMAT逻辑单项练习，有没有更好的资料推荐，非常感谢！！！！ |
