GMAT的两道题目(需要逻辑分析)
1.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.
19.Jane:Television programs and movies that depict violence among teenagers are extremely popular.Given how influential these media are,we have good reason to believe that these depictions cause young people to engage in violent behavior.Hence,depictions of violence among teenagers should be prohibited from movies and television programs,if only in those programs and movies promoted to young audiences.
Maurice:But you are recommending nothing short of censorship!Besides which,your claim that television and movie depictions of violence cause violence is mistaken:violence among young people predates movies and television by centuries.
Which one of the following,if true,most strengthens Jane’s argument?
(A) The most violent characters depicted in movies and on television programs are adult characters who are portrayed by adult actors.
(B) The movies that have been shown to have the most influence on young people’s behavior are those that are promoted to young audiences.
(C) The people who make the most profits in the movie and television industry are those who can successfully promote their work to both young and old audiences.
(D) Many adolescents who engage in violent behavior had already displayed such behavior before they were exposed violence in movies.
(E) Among the producers who make both movies and television programs,many voluntarily restrict the subject matter of films directed toward young audiences.
