lsat8-iv-18,

18. Professor Hartley's new book on moral philosophy contains numerous passages that can be found verbatim in an earlier published work by Hartley's colleague, Professor Lawrence. Therefore in view of the fact that these passages were unattributed in Hartley's book. Hartley has been dishonest in not acknowledging the intellectual debt owed to Lawrence.
Which one of the following is an assumption on which the argument is based?
(A) Hartley could not have written the new book without the passages in question.
(B) While writing the new book, Hartley had access to the manuscript of Lawrence s book.
(C) A book on moral philosophy should contain only material representing the author's own convictions.
(D) Lawrence did not get the ideas in the passages in Question or did not get their formulations originally from Hartley.
(E) Hartley considered the passages in question to be the best possible expressions of the ideas they contain.

Answer:  D but I think B
因为如果对B取非,在写书的时候hartley根本没看过Lawrence写的书,也就不存在抄袭。也就无所谓:intellectual debt owed to Lawrence.

23. Doctors in Britain have long suspected that patients who wear tinted eyeglasses are abnormally prone to depression and hypochondria. Psychological tests given there to hospital patients admitted for physical complaints like heart pain and digestive distress confirmed such a relationship. Perhaps people whose relationship to the world is psychologically painful choose such glasses to reduce visual stimulation, which is perceived as irritating. At any rate, it can be concluded that when such glasses are worn, it is because the wearer has a tendency to be depressed or hypochondriacal
23. Each of the following, if true, weakens the argument EXCEPT:
(A) Some people wear tinted glasses not because they choose to do so but because a medical condition of their eyes forces them to do so.
(B) Even a depressed or hypochondriacal person can have valid medical complaints, so a doctor should perform all the usual objective tests in diagnosing such persons.
(C) The confirmatory tests were not done for places such as western North America where the usual quality of light differs from that prevailing in Britain.
(D) Fashions with respect to wearing tinted glasses differ in different parts of the world.
(E) At the hospitals where the tests were given, patients who were admitted for conditions less ambiguous than heart pain or digestive distress did not show the relationship between tinted glasses and depression or hypochondria.
Answer: B
为什么是B啊,我怎么看其他几个除了A都不象WEAKEN

15. Goodbody, Inc., is in the process of finding tenants for its newly completed Parrot Quay commercial development, which will make available hundreds of thousands of square feet of new office space on what was formerly derelict property outside the financial center of the city. Surprisingly enough, the coming recession though it will hurt most of the city's businesses, should help Goodbody to find tenants.
Which one of the following, if true, does most to help resolve the apparent paradox?
(A) Businesses forced to economize by the recession will want to take advantage of the lower rents available outside the financial center.
(E) The recession is likely to have the most severe effect not on service industries, which require a lot of office space, but on manufacturers.
答案是A,我理解。但E好象也对吧?

非常感谢指教

1,对B取非,可得不出你说的结果,取非后的结论是在写书时没有看过他的原稿,未必在写书前没有看过,未必没有听过别人说起,种种可能都存在。

2,以前讨论过的。

3,从文中读不出E的意思,受影响才需要搬家,另找便宜的地方呀。

1. 那为什么又是D呢?
3。 E说经济萧条主要对制造业有影响。。而对于需要大量空间的服务行业影响不大。。所以虽然经济萧条,该公司的房子依然好卖.

D的意思是劳伦斯没有从哈特利得到启发云云,也就是说,劳伦斯的书虽然在前,但他也有可能是从哈特利学来的,而哈特利才是原作者。D就是排除了这种原因。

文中的主要矛盾在原本是垃圾地段的房产现在好卖了,而不是对全部地产的需求没有影响。E即使有道理,也不是最有利的支持。

3. E没有和Goodbody直接联系上, 既然你选E, 其实是你做了assumption, 这些service  industries会租Goodbody, 这种自己的假设在GMAT中是要避免的. A的正确性在于它直接将Goodbody的property和recession联系在一起.

GMAT所要求的common sense只有很窄的范围, 比如说inflation-->总体物价上涨, low wage and severe working condition-->unsatisfied employees. 这类常理是肯定正确的, 而且不需要任何专业常识.

完全明白了。。谢谢cranberry和mindfree
关键是要找和原文切得最近的。。不要加入假设。
原文A把经济萧条和郊区房子挂上了勾。
而E中service industry需要的房子和goodbody的房子还是有GAP

谢谢!收益非浅
