here is the CR question:

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

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

sharon`s argument relies on the assumption that:

A - Normal level of unemployment rarely exceeds

B - unemployment is not normally concentrated on geographically isolated
segments of population

C - the number of people who each know someone who is unemployed is always higher than 90 percent of the population

D - Roland is not consciously distorting the statistics that he presents

E - knowledge that a person acquaintance is unemployed generates more
fear of losing one`s job than does knowledge of unemployment statistics

the right answer is (B), but why??????????????

Thanks in advance
