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.

答案是A ，很奇怪，提干的两个人说的话有矛盾吗？Roland:认为本国90%。。。。
而Sharon 介绍了正常的失业率，

很奇怪，有什么关系、、

求救啊 ~~

我试着解释一下，请参考：

R主要说人们对失业人的认知度；S主要说失业率

他们的关系就是人们大都认识失业的人，会不会让他们觉得失业率很高，因为只是认识有人失业并未获知多少人失业；S的数据证明失业率不高，那么人们虽然大都知道有人失业，但是也不必恐慌失业率高。

A的总结：大都认识职业的人，但并不表示失业率高，正好总结了结论；
B：只谈失业率，没提及人们对失业人的认知度，未做到总结；
C：给出假设，引申另外一个话题，未做到总结；
D：R提供的数据是否准确，与本题无关；
E：同样引出另外一个话题，与本题无关。

不知道这样分析是否正确，请拍砖～
