58.    (34705-!-item-!-188;#058&007581)

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.

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

65.    (35041-!-item-!-188;#058&007595)

Sales of telephones have increased dramatically over the last year. In order to take advantage of this increase, Mammoth Industries plans to expand production of its own model of telephone, while continuing its already very extensive advertising of this product.

Which of the following, if true, provides most support for the view that Mammoth Industries cannot increase its sales of telephones by adopting the plan outlined above?

(A) Although it sells all of the telephones that it produces, Mammoth Industries' share of all telephone sales has declined over the last year.
(B) Mammoth Industries' average inventory of telephones awaiting shipment to retailers has declined slightly over the last year.
(C) Advertising has made the brand name of Mammoth Industries' telephones widely known, but few consumers know that Mammoth Industries owns this brand.
(D) Mammoth Industries' telephone is one of three brands of telephone that have together accounted for the bulk of the last year's increase in sales.
(E) Despite a slight decline in the retail price, sales of Mammoth Industries' telephones have fallen in the last year.
为何选E不选C？

新东方讲义上一道题  笔记标明“明星题” 重做发现完全不理解
Guidebook writer:  I have visited hotels throughout the country and have noticed that in those built before 1930 the quality of the original carpentry work is generally superior to that in hotels built afterward.  Clearly carpenters working on hotels before 1930 typically worked with more skill, care, and effort than carpenters who have worked on hotels built subsequently.




Which of the following, if true, most seriously weakens the guidebook writer’s argument?




The quality of original carpentry in hotels is generally far superior to the quality of original carpentry in other structures, such as houses and stores.
Hotels built since 1930 can generally accommodate more guests than those built before 1930.
The materials available to carpenters working before 1930 were not significantly different in quality from the materials available to carpenters working after 1930.
The better the quality of original carpentry in a building, the less likely that building is to fall into disuse and be demolished.
The average length of apprenticeship for carpenters has declined significantly since 1930.
答案选D

58. Roland说的是90% in this country，Sharon说的是normally，极限值就是globally。那么两人中间存在的gap就有可能是地域差异了。

65. 题干说的是Sales of telephones整体，而MI这家公司不一定符合大趋势。

新东方那题. 保留下来的房子是经过风雨洗刷之后留存下来的质量比较好的，而质量不好的已经都淘汰掉了，也就是“去伪存真”了，所以现在看到的1930年前建造的房子都是当时的翘楚，所以并不能说当时工人的水平比后来的要好。

58  题干里说的失业率是指全国范围内的一个平均值，那么从地方上来说并不一定就是按照这个平均值来的，可能高也可能低，所以选B

65 C的话引进了brand这个新概念，而E则是很直接说了业绩下滑，因此相对来说可能E更加适合一点

我瞎扯的~~不知道对不对~~~
