再问OG-139,谢谢!

Roland: >>

The alarming fact is that 90 percent of the people in this country now report that they know someone who is unemployed.>>

>>

LACE w:st="on">SharonLACE>: >>

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, 1 or more will very likely be unemployed.

Sharon's argument relies on the assumption that

(B) unemployment is not normally concentrated in geographically isolated segments of the population

Sharon’s argument assumes that people are generally similar in how likely they are to have among their acquaintances people who are unemployed.

以上ＯＧ解释的这句话不是很理解，请那位牛牛帮我翻译一下，谢谢！

Since heavy concentrations of unemployment in geographically isolated segments of the population would produce great differences in this respect, Sharon’s argument assumes few, if any, such concentrations. Choice B is therefore the best answer.

这段解释是对Ｂ取非，但它怎么反对Sharon的论点呢？完全看不懂，请大牛帮忙！

自己顶

不是NN，说一下我的理解。

og的意思是说unemployment的地理分布必须是均匀的，如果是不均匀的（即取非），有的地方多，有的地方少的话，那少的地方在5%的失业率的前提下可能就不会出现S说的这种if a person knows approximately 50 workers, 1 or more will very likely be unemployed情况了。

Sharon的论点是反驳R的观点的，就是失业率并不高。那么按照楼上所说，B取非后对R的观点有什么影响呢？？

自己顶

我认为sharon并没有反驳r的观点，之所以这么说更多是个discription

题目问的是 sharon的观点依赖于什么假设，因为他没说到地理因素，所以假设当然是地理因素不会影响失业率分布。

我明白楼上的意思了，因为题目只是问sharon的观点依赖于什么假设(与Roland无关)，所以假设＂地理因素不会影响失业率分布。＂则B取非，地理因素影响失业率分布，所以weaken "a normal, moderate level of unemployment"(Sharon’s argument),即unemployment就不是5%了,可能大于也可能小于5%,是这样的意思吗?

但是对ＯＧ解释好象还是不明白

Sharon’s argument assumes that people are generally similar in how likely they are to have among their acquaintances people who are unemployed.

请问这段话什么意思？

绿色那段话的意思是，由于失业经与地理因素相关性很大，每年地方失业率都不同。s的对话中没有考虑这个问题，所以B是最好答案。

黑色那段话的意思是，S是依据通过熟人的失业状况来假设的。

"S是依据通过熟人的失业状况来假设的。"与"由于失业经与地理因素相关性很大，每年地方失业率都不同。" 有什么关系啊?实在是看不懂OG的解释?

是不是说：S的arg假设在失业这个问题上人们都是一样的……

就是说S原来假设人口的相对地理隔离不存在
