So United States automakers are unwilling to pursue the development of new fuel-efficient technologies aggressively. The particular reluctance of the United States automobile industry to do so, however, could threaten the industry’s future.
虽然大型车耗油多,但目前油价很低,所以当今消费者青睐大型车. 因此,美国汽车制造商不愿意追求发展新的省油技术.然而汽车制造行业的这种做法会给该行业的未来带来危机.
Which of the following, if true, would provide the most support for the claim above about the future of the United States automobile industry?
(A) A prototype fuel-efficient vehicle, built five years ago, achieves a very high 81 miles per gallon on the highway and 63 in the city, but its materials are relatively costly.
(B) Small cars sold by manufacturers in the United States are more fuel efficient now than before the sudden jump in oil prices in 1973.
(C) Automakers elsewhere in the world have slowed the introduction of fuel-efficient technologies but have pressed ahead with research and development of them in preparation for a predicted rise in world oil prices.
世界其它各地的制造商虽然也减缓了对省油技术的引进,但坚决继续进行对该技术的研发以迎接全球油价上涨. (油价上涨后别的国家可以使用上他们已经准备好的技术,但US没有,所以会面临危机.)
(D) There are many technological opportunities for reducing the waste of energy in cars and light trucks through weight, aerodynamic drag, and braking friction.
(E) The promotion of mass transit over automobiles as an alternative mode of transportation has encountered consumer resistance that is due in part to the failure of mass transit to accommodate the wide dispersal of points of origin and destinations for trips.

大全-13-13.        One way to judge the performance of a company is to compare it with other companies. This technique, commonly called “benchmarking,” permits the manager of a company to discover better industrial practices and can provide a justification for the adoption of good practices.
Any of the following, if true, is a valid reason for benchmarking the performance of a company against companies with which it is not in competition rather than against competitors EXCEPT:
(A) Comparisons with competitors are most likely to focus on practices that the manager making the comparisons already employs.
(B) Getting “inside” information about the unique practices of competitors is particularly difficult.
(C) Since companies that compete with each other are likely to have comparable levels of efficiency, only benchmarking against noncompetitors is likely to reveal practices that would aid in beating competitors.
(D) Managers are generally more receptive to new ideas that they find outside their own industry.(E) Much of the success of good companies is due to their adoption of practices that take advantage of the special circumstances of their products of markets.

大全-12-4.        The proportion of manufacturing companies in Alameda that use microelectronics in their manufacturing processes increased from 6 percent in 1979 to 66 percent in 1990. Many labor leaders say that the introduction of microelectronics is the principal cause of the great increase in unemployment during that period in Alameda. In actual fact, however, most of the job losses were due to organizational changes. Moreover, according to new figures released by the labor department, there were many more people employed in Alameda in the manufacturing industry in 1990 than in 1979.
Which of the following, if true, would most strengthen the labor leaders’ claim concerning the manufacturing industry in Alameda?
(A) From 1979 to 1990, fewer employees of manufacturing companies in Alameda lost their jobs because of the introduction of microelectronics than did employees of manufacturing companies in the nearby community of Rockside.无关对比
(B) The figures on the use of microelectronics that were made public are the result of inquiries made of managers in the manufacturing industry in Alameda.数据来源无关
(C) The organizational changes that led to job losses in all sectors of the manufacturing industry in Alameda were primarily the result of the introduction of microelectronics.
(D) Figures on job losses in the manufacturing industry in Alameda for the late sixties and early seventies have not been made available.无关
(E) A few jobs in the manufacturing industry in Alameda could have been saved if workers had been willing to become knowledgeable in microelectronics.原文只描述结果，解决办法无关

Scientists trying to build computers that can detect spatial relations by the same kind of process have so far designed and built stationary machines. However, these scientists will not achieve their goal until they produce such a machine that can move around in its environment.
Which of the following, if true, would best support the prediction above?
(A) Human beings are dependent on visual cues from motion in order to detect spatial relations.
(B) Human beings can often easily detect the spatial relations among objects, even when those objects are in motion.
(C) Detecting spatial relations among objects requires drawing inferences from the information conveyed by light.
(D) Although human beings can discern spatial relations through their sense of hearing, vision is usually the most important means of detecting spatial relations.
(E) Information about the spatial relations among objects can be obtained by noticing such things as shadows and the relative sizes of objects.

大全-12-18.        Manager: Accounting and Billing are located right next to each other and the two departments do similar kinds of work; yet expenditures for clerical supplies charged to Billing are much higher. Is Billing wasting supplies?
Head of Billing: Not at all.
Which of the following, if true, best supports the position of the Head of Billing?
(A) There are more staff members in Accounting than in Billing.
(B) Two years ago, expenditures in Accounting for clerical supplies were the same as were expenditures that year in Billing for clerical supplies.
(C) The work of Billing now requires a wider variety of clerical supplies than it did in the past.
(D) Some of the paper-and-pencil work of both Accounting and Billing has been replaced by work done on computers.
(E) Members of Accounting found the clerical supplies cabinet of Billing more convenient to go to for supplies than their own department’s cabinet.

大全-12-19.        Most geologists believe oil results from chemical transformations of hydrocarbons derived from organisms buried under ancient seas. Suppose, instead, that oil actually results from bacterial action on other complex hydrocarbons that are trapped within the Earth. As is well known, the volume of these hydrocarbons exceeds that of buried organisms. Therefore, our oil reserves would be greater than most geologists believe.
Which of the following, if true, gives the strongest support to the argument above about our oil reserves?
(A) Most geologists think optimistically about the Earth’s reserves of oil.无关
(B) Most geologists have performed accurate chemical analyses on previously discovered oil reserves.无关
(C) Ancient seas are buried within the Earth at many places where fossils are abundant.无关
(D) The only bacteria yet found in oil reserves could have leaked down drill holes from surface contaminants.无关
(E) Chemical transformations reduce the volume of buried hydrocarbons derived from organisms by roughly the same proportion as bacterial action reduces the volume of other complex hydrocarbons.
Most geologists believe oil results from chemical transformations of hydrocarbons derived from organisms buried under ancient seas. Suppose, instead, that oil actually results from bacterial action on other complex hydrocarbons that are trapped within the Earth. As is well known, the volume of these hydrocarbons exceeds that of buried organisms.
这是一个fact，也就是前提A！
Therefore, our oil reserves would be greater than most geologists believe
这一部分是结论B！
推导方向是：A推出B！
这边有一个转换关系！
the volume of these hydrocarbons exceeds that of buried organisms这是一个fact！
而题目已经告诉我们：只有通过[B]chemical transformations和bacterial action（其实这两者的作用都是一样的）才能够转换成oil！这里就当然有一个转换比率的问题！
选项E其实就说明了这个转换比率的问题！把这个桥梁给架上了，所以support了原文的conclusion！
我觉得 CR中有很多题目都涉及到比率的问题，最主要是能把这rate给看出来！这样也就容易得多了！

大全-11-9.        In order to relieve congestion in the airspace near the airports of a certain country, transportation officials propose sending passengers by new rapid trains between the country’s major airport and several small cities within a 300-mile radius of it. This plan was proposed even though the officials realized that it is the major airport that is congested, not those in the small cities.
The plan to relieve congestion would work best if which of the following were true about the major airport?
(A) Rail tickets between the airport and the small cities will most likely cost more than the current air tickets for those routes.
(B) Most passengers who frequently use the airport prefer to reach their cities of destination exclusively by air, even if they must change planes twice.
(C) There are feasible changes in the airport’s traffic control system which would significantly relieve congestion.
(D) Some of the congestion the airport experiences could be relieved if more flights were scheduled at night and at other off-peak hours.
(E) A significant proportion of the airport’s traffic consists of passengers transferring between international flights and flights to the small cities.

However, the need to obey the letter of these restrictions has actually stimulated advertisers to create advertisements that are more inventive and humorous than they were prior to the restrictions’ introduction.
which of the following, if true, would, in conjunction with the statements above, best support the conclusion that the government policy described above fails to achieve its objective?
(A) Because of the revenues gained from the sale of alcohol and tobacco, governments have no real interest in making these products less attractive to consumers.
(B) Advertisers tend to create inventive and humorous advertisements only if they have some particular reason to do so.
(C) Banning advertising of alcohol and tobacco is a particularly effective way of making these products less attractive to consumers.
(D) With the policy in place, advertisements for alcohol and tobacco have become far more inventive and humorous than advertisements for other kinds of products.
(E) The more inventive an advertisement is, the more attractive it makes the advertised product appear.
