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

og-139

Questions 138-139 are based on the following.




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, 1 or more will very likely be unemployed.



139.


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% of the population



(D) Roland is not consciously distorting the statistics he presents



(E) knowledge that a personal acquaintance is unemployed generates more fear of losing one's job than does knowledge of unemployment statistics



B is the best answer.



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



1If normal levels of unemployment were exceeded relatively frequently, and if Roland’s figure of 90 percent were an exaggeration, Sharon’s argument would be unaffected, so choices A and D are incorrect. 2At exceptionally low levels of unemployment, Sharon’s argument suggests that choice C is likely to be false, so C is not assumed. 3The fear of losing one’s job is not part of Sharon’s argument, so choice E is incorrect.


此题有前人问过,可我还是不能理解,我认为A,B都可以!请NN指教~!


题中SHARON说的 AT ANY TIME ,和ONE OR MORE 是什么意思?为什么A不行?


首先如果是AT ANY TIME (任何时间)的话.B 也不对呀,B只是说NOT NORMALLY但也就是说还有特例呀`!


其次ONE OR MORE 是什么意思?一两个还是一个和多个,那么多个的概念可广了.


对于OG关于A的解释小弟也没有看懂.先谢谢!

对了再补充一下,如果用NOT WEAKEN的方法来看A NORMAL UNEMPLOYMENT RATE R FREQUENTLY EXCEEDED 那么SHARON 的So at any given time if a person knows approximately 50 workers, 1 or more will very likely be unemployed.的确被WEAKEN了呀.那A不也应该是答案吗?

我想我是在用NOT WEAKEN 的方法来做ASSUMPTION的题呀,这也有错吗?我糊涂了~!

PLZ  再看一下我提到的问题??????

还有为什么OG说即使是FREQUENTLY EXCEEDED 对SHARON的话也是没有影响??????明明是有影响的呀.如果这个数字总被超过的话那就一定不是在任何的时间都只有50个人中的1个UNEMPLOYED~!

不知道想法错在哪里?????请指正~!

问题是我几乎没用过not weaken做过题,靠得是逻辑意思


不过,我认为这里是只要提到normal levels,就是证实了sharon的说法,因为这个levels是sharon给出的标准,至于它超没超过要看不同地区不同情况了


而假设起的作用就是这个normal levels是如何得出来得


说到你的困惑上了吗?

我好同情黑人GG啊,我也是百思不得其解,NOT+WEAKEN应该是么的错得啊?


OG解释也很WIERD!if normal levels of unemployment were exceeded relatively frequently,S's argument would be unaffected.


难道是A取非后的意思是:不是RARELY=很频繁+一般频繁,也就是说一般失业水平偶尔超过一下,对S的结论没有影响咯。靠,这完全是根据答案想答案嘛!


LAWYER大哥能不能现身一下哈子!

这题在百思下,我有点懂了,说下心得吧。请看OG解释:Sharon’s argument assumes that people are generally similar in how likely they are to have among their acquaintances people who are unemployed. 意思也就是说,S论断的内容是人们有相似的几率在熟人中遇见失业的。也就是说R所说的90%之类不值得恐慌。A项是说一般失业水准不会超标,取非后,会超标,对结论generally similar 没有影响,顶多是遇见的失业人多点或者少点。而正确选项B取非后说到了这和地域有关,也就是说不同地域的遇见失业者的几率不同,起到了削弱的作用,故B是正确选项。谢谢,鲜花,掌声
