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.
答案选A, 相信这题大家基本上都做过了,有很多种题型,假设削弱都有,但是对于题目本身我一直有些疑问 S说的话从哪个方面反驳了R了?我没有看出他们两个对话之间的逻辑关系???
R说有90%的人说他们知道有人失业 S说这并不稀奇,然后就举了一个失业率5%的例子。 还是没有看懂???希望大家帮帮忙~~~~非常感谢!~~
