题目：

Budget constraints have made police officials consider reassigning a considerable number of officers from traffic enforcement to work on higher-priority, serious crimes. Reducing traffic enforcement for this reason would be counterproductive, however, in light of the tendency of criminals to use cars when engaged in the commission of serious crimes. An officer stopping a car for a traffic violation can make a search that turns up evidence of serious crime.

Which of the following, if true, most strengthens the argument given?

选项:

A、
A. An officer who stops a car containing evidence of the commission of a serious crime risks a violent confrontation, even if the vehicle was stopped only for a traffic violation.
B、
B. When the public becomes aware that traffic enforcement has lessened, it typically becomes lax in obeying traffic rules.
C、
C. Those willing to break the law to commit serious crimes are often in committing such crimes unwilling to observe what they regard as the lesser constraints of traffic law.
D、
D. The offenders committing serious crimes who would be caught because of traffic violations are not the same group of individuals as those who would be caught if the arresting officers were reassigned from traffic enforcement.
E、
E. The great majority of persons who are stopped by officers for traffic violations are not guilty of any serious crimes.

文章：

    Manufacturing site location is an important consideration in determining the optimal deployment of a firm's production resources, but one that is usually given only limited attention. Decisions about location are often based purely on quantitative analyses that trade off transportation costs, economies of scale, and other costbased variables. This practice, however, can lead to suboptimal results, as decision-makers tend to focus only on easily quantifiable factors. A further disadvantage of strictly cost-based methods is that they tend to focus on cost advantage factors, which are often transitory. Government regulations, tax systems, and exchange rates can quickly change. Strategies based on such parameters may eventually be rendered obsolete by the very factors that first created an advantage.

    In contrast, qualitative issues, which are frequently neglected in choosing manufacturing site locations, are often central to creating and supporting a competitive advantage. For example, the level of skill possessed by the local workforce varies with location; consequently, location can affect the bility of firms to implement skill-based process technologies. When formulating a site location strategy, companies should therefore emphasize qualitative factors to ensure that the chosen strategy supports the company's overall business strategy. Only after establishing a set of desirable location options should companies refine choices using cost-based factors.

题目：

According to the passage ,analysis of quantitative factors is best used for which of the following ?

选项:

A、Determining strategies for offsetting qual-itative disadvantages in manufacturing site locations
B、Evaluating manufacturing site-location parameters affecting long-term competitive advantage
C、Choosing manufacturing site locations that have access to optimal workforce populations
D、Narrowing manufacturing site-location options arrived it through qualitative analysis
E、Making decisions about business considerations other than location of manufacturing sites

D

题目：

Supply shortages and signs of growing demand are driving cocoa prices upward. Unusually severe weather in cocoa-producing regions—too much rain in Brazil and too little in West Africa—has limited production. Further, Europe and North America recently reported stronger demand for cocoa. In the first quarter, grinding of cocoa beans—the first stage in processing cocoa for chocolate—rose 8.1 percent in Europe and 16 percent in North America. Analysts have concluded that cocoa's price will continue to rise at least into the near future.

Which of the following would, if true, most strengthen the reasoning above?

选项:

A、Ground cocoa beans can be stored for long periods before they spoil.
B、Several European and North American manufacturers that use cocoa have recently improved their processing capacity.
C、It takes new cocoa trees five or six years before they start bearing fruit.
D、Governments in Europe and North America are likely to change current restrictions on cocoa imports.
E、Historically, cocoa production has varied widely from year to year.

题目：

Economist: The price of tap water in our region should be raised drastically. Supplies in local freshwater reservoirs have been declining for years because water is being used faster than it can be replenished. Since the price of tap water has been low, few users have bothered to adopt even easy conservation measures.

The two sections in boldface play which of the following roles in the economist’s argument?

选项:

A、The first is a conclusion for which support is provided, and which in turn supports the main conclusion; the second is the main conclusion.
B、The first is an observation for which the second provides an explanation; the second is the main conclusion but not the only conclusion.
C、The first is a premise supporting the argument’s main conclusion; so is the second.
D、The first is the only conclusion; the second provides an explanation for the first.
E、The first is the main conclusion; the second is a conclusion for which support is provided, and which in turn supports the first.

题目：

Mansour: We should both plan to change some of our investments from coal companies to less polluting energy companies. And here’s why. Consumers are increasingly demanding nonpolluting energy, and energy companies are increasingly supplying it.

Therese: I'm not sure we should do what you suggest. As demand for nonpolluting energy increases relative to supply, its price will increase, and then the more polluting energy will cost relatively less. Demand for the cheaper, dirtier energy forms will then increase, as will the stock values of the companies that produce them.

Therese responds to Mansour’s proposal by doing which of the following?

选项:

A、Advocating that consumers use less expensive forms of energy
B、Implying that not all uses of coal for energy are necessarily polluting
C、Disagreeing with Mansour’s claim that consumers are increasingly demanding nonpolluting energy
D、Suggesting that leaving their existing energy investments unchanged could be the better course
E、Providing a reason to doubt Mansour’s assumption that supply of nonpolluting energy will increase in line with demand

Art historian: Unlike many artistic traditions that sought to depict plants native to the local area in a seasonally appropriate way (for example, depicting scenes of spring with the plants in the appropriate stages of development for that season), seventeenth-century Dutch artists specializing in flower paintings almost exclusively chose to depict exotic species of flowers from outside the local area. Painting such species was worthwhile primarily because the art-buying public had developed a strong preference for images of the exotic. The great botanical centers of the time gave the artists direct access to such flowers, which the artists would freely combine in a single painting, regardless of whether the combined species occurred together in the wild, and depicted each in full bloom, regardless of whether those species bloomed at the same time in nature.

Statement: The art historian makes the point that the species of flowers these Dutch artists chose to paint were 1 largely because the species were 2 .

Select for 1 and for 2 the options that complete the statement so that it is most strongly supported by the information provided. Make only two selections, one in each column.

Tiger beetles are such fast runners that they can capture virtually any nonflying insect.  However, when running toward an insect, the beetles intermittently stop, and then, a moment later, resume their attack.  Perhaps they cannot maintain their pace and must pause for a moment's rest; but an alternative hypothesis is that while running tiger beetles are unable to process the resulting rapidly changing visual information, and so quickly go blind and stop.
 
Which of the following, if discovered in experiments using artificially moved prey insects, would support one of the two hypotheses and undermine the other?
