is a circumstance on which that judgment is, in part based.
D. The first is a judgment that has been offered in support of the position that the argument calls into question; the second
is that position. E. The first is a claim that the argument calls into question; the second is the position taken by the argument. ----------------------------------------------------------------------------------------- 32. GWD-23-Q10
When trying to identify new technologies that promise to transform the marketplace, market researchers survey the
managers of those companies that are developing new technologies. Such managers have an enormous stake in succeeding, so they invariably overstate the potential of their new technologies. Surprisingly, however, market researchers typically do not survey a new technology‘s potential buyers, even though it is the buyers-not the producers-who will ultimately determine a technology‘s commercial success.
Which of the following, if true, best accounts for the typical survey practices among market researchers?
A. If a new technology succeeds, the commercial benefits accrue largely to the producers, not to the buyers, of that
technology. B. People who promote the virtues of a new technology typically fail to consider that the old technology that is
currently in use continues to be improved, often substantially. C. Investors are unlikely to invest substantial amounts of capital in a company whose own managers are skeptical
about the commercial prospects of a new technology they are developing. D. The potential buyers for not-yet-available technologies can seldom be reliably identified.
E. The developers of a new technology are generally no better positioned than its potential buyers to gauge how
rapidly the new technology can be efficiently mass-produced.
Q10 类型 Paradox
题目提出的是一个矛盾: 1. 在衡量新技术的市场潜力时,研发经理的态度是有偏向的.(这个我深有体会..呵呵..)
2. 但是市场通常不调查新技术的最终用户(而是调查研发经理).尽管最终用户的影响决定该技术的前景. Paradox的正确选项要能解释矛盾的双方面,即1,2要同时成立. D:指出新技术的最终用户是很难identify的.1,2同时成立.
D有让1,2都成立吗？好象没有，只使2成立了，不过只要充分即可，所以对。 ----------------------------------------------------------------------------------------- 36. GWD25-Q36
The chemical adenosine is released by brain cells when those cells are active. Adenosine then binds to more and more sites on cells in certain areas of the brain, as the total amount released gradually increases during wakefulness. During sleep, the number of sites to which adenosine is bound decreases. Some researchers have hypothesized that it is the cumulative binding of adenosine to a large number of sites that causes the onset of sleep.
Which of the following, if true, provides the most support for the researchers‘ hypothesis?
A. Even after long periods of sleep when adenosine is at its lowest concentration in the brain, the number of brain cells
bound with adenosine remains very large. B. Caffeine, which has the effect of making people remain wakeful, is known to interfere with the binding of adenosine to
sites on brain cells. C. Besides binding to sites in the brain, adenosine is known to be involved in biochemical reactions throughout the body. D. Some areas of the brain that are relatively inactive nonetheless release some adenosine.
E. Stress resulting from a dangerous situation can preserve wakefulness even when brain levels of bound adenosine are
high.
设A为：adenosine；B为：sleep;
原文结论说的是：有A则有B：A——> B：
adenosine累积到大量的sites时，启动了睡眠；
41
选项B
说：
没有A就没有B
：无
A——>无 B：
Caffeine，妨碍了adenosine累积（无A），因此人保持清醒（不想睡，既无B），从反面支持了原来的结论。

Plantings of cotton bioengineered to produce its own insecticide against bollworms, a major cause of crop failure, sustained little bollworm damage until this year. This year the plantings are being seriously damaged by bollworms. Bollworms,
however, are not necessarily developing resistance to the cotton‘s insecticide. Bollworms breed on corn, and last year more corn than usual was planted throughout cotton-growing regions. So it is likely that the cotton is simply being overwhelmed by corn-bred bollworms.
In evaluating the argument, which of the following would be most useful to establish?
A. Whether corn could be bioengineered to produce the insecticide
B. Whether plantings of cotton that does not produce the insecticide are suffering unusually extensive damage from
bollworms this year C. Whether other crops that have been bioengineered to produce their own insecticide successfully resist the pests
against which the insecticide was to protect them D. Whether plantings of bioengineered cotton are frequently damaged by insect pests other than bollworms
E. Whether there are insecticides that can be used against bollworms that have developed resistance to the insecticide
produced by the bioengineered cotton
这题说， 棉花有抵制那个虫子的anti
但是还是受害了，因为玉米是虫子变得很多 这样的话，也就是说有两个结论
玉米是棉花受害，棉花本身的anti有用
B说的是，如果棉花没有anti的话，虫子会不会对他造成极大伤害
这样，如果是， 说明anti有用， 如果不是，说明anti没用 于是， 按照原文的意思就是， 如果是，原文成立， 如果不是，原文不成立
这个题的中心是棉花的anti是自己没用呢？还是被corn给盖过了
所以要evaluate他，就要看那些没有anti的棉花是不是遭受了更大的伤害
My opinion: 此题是否偷换了概念。Plantings of cotton bioengineered to produce its own insecticide against bollworms与This year the plantings是否是同一个东西。

Consumers planning to buy recreational equipment tend to buy higher quality, more expensive equipment when the
economy is strong than when it is weak. Hill and Dale is a business that sells high-quality, expensive camping and hiking equipment in Boravia. Although all the signs are that Boravia‘s economy is now entering a period of sustained strength, the managers of the business do not expect a substantial increase in sales.
Which of the following, if true, would provide the strongest justification for the managers‘ judgment?
A. A significant proportion of Hill and Dale‘s sales are made to customers who enter the store in order to buy one particular
item but, once there, find other items to buy as well. B. In Boravia when the economy is strong, those who might otherwise go camping tend to take vacations overseas. C. The economic upturn is likely to allow Boravia‘s national parks, where most of the camping and hiking is done, to
receive extra funding to improve their visitor facilities. D. Advances in materials technology have led to the development of hiking and camping equipment that is more
comfortable and lightweight than before. E. Many people in Boravia not only are committed to preserving the country‘s wilderness areas but also are interested in
spending some time in them. ------------------------------------------------------------------------------------------------------- 10. GWD26-Q10
Lawmaker: Raising taxes is not the only means of reducing government debt. The government‘s stockpile of helium is worth 25 percent more, at current market prices, than the debt accumulated in acquiring and storing it. Therefore, by selling the helium, the government can not only pay off that debt but reduce its overall debt as well. Which of the following is an assumption on which the argument depends? A. The government has no current need for helium.
B. Twenty-five percent of the debt the government has accumulated in stockpiling helium is not an insignificant portion of
the government‘s total debt. C. It is not in the lawmaker‘s interest to advocate raising taxes as a means of reducing government debt. D. Attempts to sell the government‘s helium will not depress the market price of helium by more than 25 percent. E. The government will not incur any costs in closing its facilities for stockpiling helium.
有两个方向的想法。首先A去非。美国政府有hel的需要，这并不意味着美国就不能卖hel，题目的主线是卖hel 可不可以还债。即使美国政府需要hel,他还可以去卖hel还债。 除非说All of the hel available is to be needed by US industry.这样hel就不能卖了。 C得说法是卖了25%得不会导致价钱降低。取非以后以后就是说卖了25%会导致hel无利可图。题目的主线是卖hel有利可图，所以卖hel还债。 C非，就是断桥削弱。
3.26-10的BY出现在结论,是作者得出结论的前提,即作者在结论成立的前提是SELLING成功.所以不能SELLING的情况和作者的结论无关.
4.D的取非是:Attempts to sell the government’s helium will depress the market Price of helium by mor
e than 25 percent. 即贬值超过25%.原来比债务高于25%.这样贬值后就不能全部还债(pay off)
5.考试时时间很短,所以不可能很细计算,意味着出题人不会考细的东西,只会考大方向.所以不可能答案错在小计算上 lawyer

A medieval manuscript called L contains all eighteen extant tragedies by the Greek playwright Euripides. Of these, ten called the ―select plays,‖ are accompanied in L by ancient commentaries and also appear in other medieval manuscripts; this group includes some of Euripides‘ best-known works, including the Medea. The other eight, which appear in alphabetical order, without commentary. The Electra is one of the alphabeticals.
Which of the following can be reliably concluded on the basis of the Statements given?
A. Only Euripides‘ best-known works are accompanied by ancient commentaries in extant medieval manuscripts. B. The select plays are accompanied by ancient commentaries because they were the best known of Euripides‘ works. C. No commentaries were written about Euripides‘ Electra in ancient times.
D. Euripides‘ Medea never appears in medieval manuscripts unaccompanied by ancient commentary. E. Euripides‘ Electra does not appear accompanied by a commentary in any extant medieval manuscript.
想啊想，终于想明白为什E对。
ABCD都可以排除，对于E，有的G友说应该把any 改成all才对。我想E这个句子存在一个理解问题：
Euripides’ Electra does not appear accompanied by a comentary in any extant medieval manuscript.
若理解成：在任何一部extant medieval manuscript中E都不伴随评论出现。则这道题没答案了。
但我想GMAC愿意是： 强调does not appear accompanied by a comentary in any extant medieval manuscript
不是在任何一部extant medieval manuscript中，E都是以伴随评论出现的。因此正符合原文意思。
没选E的同学可能很难一下子把原来的逻辑转回来，唯一的办法就是多念几遍这个句子了。
******************************************************* 39楼的mm,你好牛. 我觉得你的解释是正确的!!!也是唯一合理的!
其实E想说: Euripides的Electra这个剧本,并不每次都是伴随这评论出现在当今现存的手稿里的( 起码在L这部手稿里,就没带评论).

Excavations of the Roman city of Sepphoris have uncovered numerous detailed mosaics depicting several readily identifiable animal species: a hare, a partridge, and various Mediterranean fish. Oddly, most of the species represented did not live in the Sepphoris region when these mosaics were created. Since identical motifs appear in mosaics found in other Roman cities, however, the mosaics of Sepphoris were very likely created by traveling artisans from some other part of the Roman Empire.
Which of the following is an assumption on which the argument depends?
A. The Sepphoris mosaics are not composed exclusively of types of stones found naturally in the Sepphoris area. B. There is no single region to which all the species depicted in the Sepphoris mosaics are native.
C. No motifs appear in the Sepphoris mosaics that do not also appear in the mosaics of some other Roman city. D. All of the animal figures in the Sepphoris mosaics are readily identifiable as representations of known species. E. There was not a common repertory of mosaic designs with which artisans who lived in various parts of the Roman
Empire were familiar.
