4. Speaker: Contemporary business firms need to recognize that avoiding social responsibility leads to the gradual erosion of power. This is Davis and Blomstrom’s Iron Law of Responsibility: “In the long run, those who do not use power in a manner which society considers responsible will tend to lose it.” The law’s application to human institutions certainly stands confirmed by history. Though the “long run” may require decades or even centuries in some instances, society ultimately acts to reduce power when society thinks it is not being used responsibly. Therefore, a business that wishes to retain its power as long as it can must act responsibly.
计时：43.90s
逻辑链：根据一个铁则：长期来看，没有负责地行使权力的人总会失去权力，这个铁则被历史证明了，所以希望保留自己的权力的公司应该要负责地行使权力。
推测：公司持续期很短的公司不用这样
Which one of the following statements, if true, most weakens the speaker’s argument?
(A) Government institutions are as subject to the
Iron Law of Responsibility as business
institutions. 无关 对象是business
(B) Public relations programs can cause society to
consider an institution socially responsible
even when it is not. 无关
(C) The power of some institutions erodes more
slowly than the power of others, whether they
are socially responsible or not. 无关 erode的速度没关系
(D) Since no institution is eternal, every business
will eventually fail. 正确
(E) Some businesses that have used power in
socially responsible ways have lost it. 无关 个别的不能weaken

Which of the following most logically completes the argument?
United States manufacturers currently produce most of the world's solar-power generators--most of which are exported to Europe. However, European manufacturers are emerging and probably will ultimately capture much of the European market. The United States government is funding initiatives intended to encourage use of solar power within the United States. If these initiatives succeed in increasing the demand for solar-power generators in the United States, United States manufacturers will probably maintain significant production levels, since __________.
逻辑链：US的生产商本来大量出口产品到欧洲但是现在欧洲的生产商崛起了而且抢占了欧洲市场，US政府鼓励在US使用太阳能从而增加对这种产品的需求，如此一来US的生产商可能还是可以维持原来的生产水平
推测：原来的US市场很小
(A) some United States manufacturers have been substantially increasing their output over the last several years 无关
(B) the efficiency of solar-power generators in converting energy from the Sun into electric power is not improving as fast as it once did 无关
(C) just as European manufacturers enjoy certain competitive advantages in Europe, so do United States manufacturers in the United States
(D) European governments are currently undertaking initiatives to stimulate the use of solar power within Europe 无关
(E) the current market for solar-power generators in the United States is very limited 正确

The higher the level of certain vitamins and minerals in the bloodstream, the better a person's lung function, as measured by the amount of air the person can expel in one second. The lung function of smokers is significantly worse, on average, than that of nonsmokers. Clearly, therefore, one way for smokers to improve their lung function is for them to increase their intake of foods that are rich in these helpful vitamins and minerals.
提出的方法要保证它有效，要确定是可行的，效果不会受到影响
Which of the following is an assumption on which this argument depends?
(A) Smokers are less likely than nonsmokers to have diets that are rich in vitamins and minerals. 无关
(B) The lung function of smokers whose diets are rich in those vitamins and minerals is generally better than that of nonsmokers with comparable diets. 无关
(C) People whose diets are deficient in those vitamins and minerals do not typically have other health problems in addition to diminished lung function. 无关
(D) Stopping smoking will not typically improve lung function more than any diet changes can. 无关
(E) Smoking does not introduce into the body chemicals that prevent the helpful vitamins and minerals from entering the bloodstream. 正确

Astronomer: Observations of the Shoemaker-Levi comet on its collision course with Jupiter showed that the comet broke into fragments before entering Jupiter's atmosphere in 1994, but they did not show how big those fragments were. In hopes of gaining some indication of the fragments' size, astronomers studied spectrographic analyses of Jupiter's outer atmosphere. These analyses revealed unprecedented traces of sulfur after the fragments' entry. The fragments themselves almost certainly contained no sulfur, but many astronomers believe that the cloud layer below Jupiter's outer atmosphere does contain sulfur. Since sulfur would have seeped into the outer atmosphere if comet fragments had penetrated this cloud layer, it is likely that some of the fragments were at least large enough to have passed through Jupiter's outer atmosphere without being burned up.
In the astronomer's argument, the two portions in boldface play which of the following roles?
(A) The first presents a circumstance for which the astronomer offers an explanation; the second is part of that explanation.
(B) The first acknowledges a consideration that weighs against the conclusion of the argument; the second is that conclusion.
(C) The first acknowledges a consideration that weighs against the conclusion of the argument; the second provides evidence in support of that conclusion.
(D) The first provides evidence in support of the conclusion of the argument; the second acknowledges a consideration that weighs against that conclusion.
(E) The first is a judgment advanced in support of the conclusion of the argument; the second is that conclusion.正确

Most of the world's supply of uranium currently comes from mines. It is possible to extract uranium from seawater, but the cost of doing so is greater than the price that uranium fetches on the world market. Therefore, until the cost of extracting uranium from seawater can somehow be reduced, this method of obtaining uranium is unlikely to be commercially viable.
Which of the following would it be most useful to determine in evaluating the argument?
逻辑链：如今大部分的U都是矿产，U也可以从海里面提取，但是cost要比如今他在市面上的价格高得多，所以除非cost能下降，从海中提取U的方法在商业上不可行。
推测：可能可以价格升高
(A) Whether the uranium in deposits on land is rapidly being depleted 无关
(B) Whether most uranium is used near where it is mined 无关
(C) Whether there are any technological advances that show promise of reducing the cost of extracting uranium from seawater 正确
(D) Whether the total amount of uranium in seawater is significantly greater than the total amount of uranium on land 无关
(E) Whether uranium can be extracted from freshwater at a cost similar to the cost of extracting it from seawater 无关 |
