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 one 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 (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 percent of the population (D) Roland is not consciously distorting the statistics he presents (E) knowledge that a personal acquaintance is unemployed 答案是B
这道题看不透: 1.知道B选项为什么对,不知道其它四个选项错的原因都是什么,请指教; 2.这两个人说的话有什么关联吗?一个反驳另一个?还是一个提起个话头,另一个发表了相关的一番言论,但是两人的话没什么逻辑关系? |
