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

Sharon

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

Sharon's argument is structured to lead to which of the following as aconclusion?
(A) The fact that 90% of the peopleknow someone who is unemployed is not an indication that unemployment isabnormally high.

(B) The current level of unemploymentis not moderate.

(C) If at least 5% of workers areunemployed, the result of questioning a representative group of people cannotbe the percentage Roland cites.

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

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



题干暗含了什么意思? 求牛人解释, 不胜感激!!

试试看解答
R说:本国90%的人报告说他们认识失业的人,这有警示作用
S答:但正常的失业率是5%,也即20人中有1人失业。所以,如果一个人认识大约50人,那么其中有1+失业者。(也就是说认识失业的人是正常现象)
题目是conclusion类。
A:S的意思是这个失业状况并不能说明失业率异常高。正确。

有点感觉了,但是 为什么说 1个人认识50个工人, 那么就有1+个人失业呢?
