GMAT每日一题-逻辑第56题

作者:英吉
        Roland:  The alarming fact is that 90 percent of the people in this country now report that they know someone who is unemployed.

        Sharon:  But a normal, moderate level of unemployment is 5 percent, with 1 out of 20 workers unemployed.  So at any given time if a person knows approximately 50 workers, 1 or more will very likely be unemployed.

        Sharon's argument is structured to lead to which of the following as a conclusion?

        (A) The fact that 90% of the people know someone who is unemployed is not an indication that unemployment is abnormally high.

        (B) The current level of unemployment is not moderate.

        (C) If at least 5% of workers are unemployed, the result of questioning a representative group of people cannot be the percentage Roland cites.

        (D) It is unlikely that the people whose statements Roland cites are giving accurate reports.

        (E) If an unemployment figure is given as a certain percent, the actual percentage of those without jobs is even higher.

        题目分析:A说90%的人认识失业的人不证明失业率很高,原文反复谈的就是这两者之间的关系,留着。B说现有失业率并不moderate,这个即便原文说过也不符合问题,问题问的是后面那个家伙说的话能导致什么结论?正确答案至少得和原文方向一样,这个选项方向和原文相反,杀。C说如果至少5%的人没工作,后面那个家伙引用的不是前面那个家伙引用的范围,杀。D说调查人群不太可能给出准确的report,没说,杀。E如果失业率在一定的百分比,等一会,在一定的百分比是原文说的那个百分比吗?有可能是,有可能不是,如果此选项作为答案则考生之间会有争议了,有人认为是原文那个百分比,有人不这么认为,标准化考试的正确答案不会这么出!
