试题详情
题目：
Roland: The alarming fact is that 90 percent of the people in this country now report that they know someone who is unemployed.

Sharon's argument relies on the assumption that
选项:
A、normal levels of unemployment are rarely exceeded
B、unemployment is not normally concentrated in geographically isolated segments of the population
C、the number of people who each know someone who is unemployed is always higher than 90% of the population

答案:

提问：
