5. According to an independent computer-industry analyst, the new Regent microcomputer is of high quality, is fast, and costs less than any currently existing competing model. It is reasonable to conclude, therefore, as the manufacturer’s prospectus does, that the Regent will quickly establish itself as a fast-selling, low-priced alternative to currently available microcomputers.
Which of the following, if true, would LEAST weaken the argument above?
(A) Many retailers already carry one or more low-priced microcomputer models and are disinclined to carry another.
(B) Several faster and lower-priced models of microcomputers will soon be introduced by other computer manufacturers.
(C) The Regent Corporation’s microcomputer can be used in conjunction with higher-priced microcomputers manufactured by other companies.
(D) Most of those individuals and companies that could be expected to make up the potential market for the Regent microcomputer have already filled their microcomputer needs.（C）
(E) The independent computer-industry analyst whose assessment was incorporated in the prospectus has used measures of quality that are not universally accepted by the computer-buying public.
why is E not right?作者: saffsa761 时间: 2013-5-8 19:25
E是明显的weaken,通过说明分析师使用的标准不是行业所认同的，从而说明的到的is of high quality, is fast, and costs less than any currently existing competing model--结论是不可靠的，作者: waytousff 时间: 2013-5-9 06:31
thanks. you are so warmhearted.你在做大全吗？ 我正在做。作者: saffsa761 时间: 2013-5-9 21:09
我已经来不及做大全了，cr只做了og,gwd,feifei logic
大家多多讨论才能提高嘛
+U吧！作者: francoisw 时间: 2013-5-11 10:30
这题我开始也错了 后来我理解是 conclusion是 R computer as a alternative to available computer
C选项里 说可以conjunct with 所以weaken了conclusion
ABD都是无关 E是radically weaken
不知道这样理解对不对
请NN指教
