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
