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, one or more will very likely be unemployed.
Sharon's argument relies on the assumption that
normal levels of unemployment are rarely exceeded
unemployment is not normally concentrated in geographically isolated segments of the population
the number of people who each know someone who is unemployed is always higher than 90 percent of the population
Roland is not consciously distorting the statistics he presents
knowledge that a personal acquaintance is unemployed generates more fear of losing one's job than does knowledge of unemployment statistics
CR：S说90%的人认识一个以上失业的很正常，因为如果失业率哪怕只有5%，20个人里有一个人失业，那么如果一个人认识50个人，则里面有一两个失业的相当正常。
A，normal levels of unemployment are rarely exceeded.正常的失业率很少被超过。CR：这个应该是题目已经给定的事实，而不是S的假设之一。因为在S的概念里， a normal, moderate level of unemployment is 5 percent，即5%和正常的失业率是一个东西。

rarely，很少地，稀有地
merely，仅仅，只是
