Kate: The recent decline in numbers of the Tennessee warbler, a North American songbird that migrates each fall to coffee plantations in South America, is due to the elimination of the dense tree cover that formerly was a feature of most South American coffee plantations.

Scott: The population of the spruce budworm, the warbler‘s favorite prey in North America, has been dropping. This is a more likely explanation of the warbler‘s decline.

Which of the following, if true, most seriously calls Scott‘s hypothesis into question?

A. The numbers of the Baltimore oriole, a songbird that dose not eat budworms but is as dependent on South

American coffee plantations as is the Tennessee warbler, are declining. B. The spruce-budworm population has dropped because of a disease that can infect budworms but not Tennessee

warblers. C. The drop in the population of the spruce budworm is expected to be only temporary.

D. Many Tennessee warbler have begun migrating in the fall to places other than traditional coffee plantations. E. Although many North American songbirds have declined in numbers, no other species has experienced as great a

decline as has the Tennessee warbler. ------------------------------------------------------------------------------------------------------- 41.: GWD-23-Q39

In Gandania, where the government has a monopoly on tobacco sales, the incidence of smoking-related health problems has risen steadily for the last twenty years. The health secretary recently proposed a series of laws aimed at curtailing tobacco use in Gandania. Profits from tobacco sales, however, account for ten percent of Gandania‘s annual revenues. Therefore, Gandania cannot afford to institute the proposed laws.

Which of the following, if true, most seriously weakens the argument? A. All health care in Gandania is government-funded.

B. Implementing the proposed laws is not likely to cause a significant increase in the amount of tobacco Gandania exports. C. The percentage of revenue Gandania receives from tobacco sales has remained steady in recent years. D. Profits from tobacco sales far surpass any other single source of revenue for the Gandanian government. E. No government official in Gandania has ever previously proposed laws aimed at curtailing tobacco use.

找了个牛人的解释：烟草赚钱是事实，不能ban是结论 说烟草导致病增多

然后因为烟草是收入， 所以不能ban烟草

这里的主要推力是，因为烟草带来钱，所以不能ban weaken要去反对说烟草可以ban

C，说烟草收入稳定。。 这样要是ban了，不就木有钱拉 所以C是support A是这么说的，政府要出钱看病

这样不ban烟草，导致大家得病，于是政府就用卖烟的钱来给大家治病 那不是还不如不卖烟阿

2. GWD-27-Q2:

Electronic computer chips made of tiny silicon wafers now regularly contain millions of electronic switches. Unfortunately, electronic switches that are this small cannot withstand intense radiation. Micro-Mechanics plans to produce a chip that, because it uses only microscopic mechanical switches, will be invulnerable to radiation damage. The switches will, however, be slower than electronic switches and the chip will contain only 12,000 switches.

For there to be a market for Micro-Mechanics‘ chip as a result of the apparent advantage described above, each of the following would have to be true EXCEPT:

A. There will be applications in which the speed attainable by an electronic switch is not essential.

B. Switches used on electronic chips that contain only 12,000 switches are more vulnerable to radiation damage than

the switches on Micro-Mechanics‘ chip will be. C. There will be applications for computer chips in environments where the chips may have to survive intense radiation. D. Some devices in which computer chips will be used will have other components that will be able to function during

or after exposure to radiation. E. Manufacturers are able to protect electronic computer chips against exposure to intense radiation, where this

protection is necessary. 解析：原文推理：electronic switches不能忍受intense radiation，Micro-Mechanics‘ chip可以忍受，但是slower than electronic switches，结论说Micro-Mechanics‘ chip有市场，也就是说就算慢也可以

思路：要加强有市场，就要强调Micro-Mechanics‘ chip能够抗击radiation damage的优点，淡化速读慢的缺点。 A：说速度不重要，自然就去除了慢这个缺点，也就有市场了。

B：相同的速读下electronic chips比Micro-Mechanics‘ chip更脆弱，加强了Micro-Mechanics‘ chip抗击radiation damage的能力

C：chips may have to survive intense radiation说明抗击radiation damage很重要，因此有市场

D：错误是认为其他组成部分是否能够忍受radiation damage和Micro-Mechanics‘ chip有市场无关。但是这个选项说明使用Micro-Mechanics‘ chip没有副作用。之前使用electronic switches的时候因为不能忍受intense radiation，所以只能在弱radiation的情况下使用，现在换成了Micro-Mechanics‘ chip，也就是说可以在强radiation下使用，但是如果装置中的其他零件不能忍受强radiation的话，就算是换上了Micro-Mechanics‘ chip也不能用，所以也就没有市场了。这个选项排除了这种情况。 E：正确，很明显的错误，electronic computer chips可以被保护不受radiation damage，那么就不需要Micro-Mechanics‘ chip了，削弱结论

Political advocacy groups have begun to use information services to disseminate information that is then accessed by the public via personal computer. Since many groups are thus able to bypass traditional news sources, whose reporting is selective, and to present their political views directly to the public, information services present a more balanced picture of the complexities of political issues than any traditional news source presents.
