(This passage was adapted from an article written in 1990.)

    Research data indicate that there is a great deal of poverty in the United States among singleparent families headed by women. This problem could result from the fact that women's wages are only 60 percent of men's. Some economists believe that rigorous enforcement of existing equal pay laws would substantially decrease this wage inequity. But equal pay laws are ineffectual when women and men are concentrated in different occupations because such laws require only that women and men doing the same jobs be paid the same. Since gender concentration exists (for example, 80 percent of clerical workers are women), other economists argue that a comparable worth standard, which would mandate that women and men in any jobs that require comparable training and responsibility be paid the same, should be applied instead. But some policy analysts assert that, although comparable worth would virtually equalize male and female wages, many singleparent families headed by women would remain in poverty because many men earn wages that are below the poverty line. These policy analysts believe that the problem is not caused primarily by wage inequity but rather by low wages coupled with single parenthood, regardless of sex. As a solution, they challenge the government's assumption that a family's income should depend primarily on wages and urge the government to provide generous wage supplements (child and housing allowances) to single parents whose wages are low.

题目:

Which of the following is most clearly an example of the policy advocated by the policy analysts mentioned in the highlighted text?

选项:

A、A government provides training to women who wish to move out of occupations in which women are concentrated.
B、A government supports research that analyzes the connection between wage inequality and poverty among single-parent families headed by women.
C、A government surveys wages annually to make certain that women and men in the same jobs receive the same pay.
D、A government analyzes jobs in terms of the education and responsibility they require and publishes a list of jobs that should be considered equivalent for wage purposes.
E、A government provides large rent subsidies to single parents whose wages are less than half the average worker's wage.

文章:

    A key decision required of advertising managers is whether a "hard-sell" or "soft-sell" strategy is appropriate for a specific target market. The hard-sell approach involves the use of direct, forceful claims regarding the benefits of the advertised brand over competitors' offerings. In contrast, the soft-sell approach involves the use of advertising claims that imply superiority more subtly

    One positive aspect of the hard-sell approach is its use of very simple and straightforward product claims presented claims presented as explicit conclusions, with little room for confusion regarding the advertiser's message. However, some consumers may resent being told what to believe and some may distrust the message. Resentment and distrust often lead to counterargumentation and to boomerang effects where consumers come to believe conclusions diametrically opposed to conclusions endorsed in adverrising claims, By contrast, the risk of boomerang erects is greatly reduced with soft-sell approaches. One way to implement the soft-sell approach is to provide information that implies the main conclusions the advertiser wants the consumer to draw, but leave the conclusions themselves unstated. Because consumers are invited to make up their own minds, implicit conclusions reduce the risk of resentment ,distrust, and counter argumentation.

    Recent research on consumer memory and judgment suggests another advantage of implicit conclusions. Beliefs or conclusions that are self-generated are more accessible from memory than beliefs from conclusions provided explicitly by other individuals, and thus have a greater impact on judgment and decision making. Moreover, self-generated beliefs are often perceived as more accurate and valid than the beliefs of others, because other individuals may be perceived as less less knowledgeable, or may be perceived as manipulative or deliberately misleading. Despite these advantages, implicit conclusions may mot always be more effective than explicit Conclusions. One risk is that some consumers may fail to draw their own conclusions and thus miss the point of the message. .Inferential activity is likely only when consumers are motivated and able to engage in effortful cognitive processes. Another risk is that some conSummers may draw conclusions Other than the one intended ,Even if inferential activity is likely there is no guarantee that consumers will follow the path provided by the advertiser. Finally, a third risk is that consumers may infer the intended conclusion but question the validity of their inference.

The primary purpose of the passage is to

选项:

A、point out the risks involved in the use of a particular advertising strategy
B、make a case for the superiority of one advertising strategy over another
C、illustrate the ways in which two advertising strategies may be implemented
D、present the advantages and disadvantages of two advertising strategies
E、contrast the types of target markets for which two advertising strategies are appropriate

State spokesperson:Many businesspeople who have not been to our state believe that we have an inadequate road system.Those people are mistaken, as is obvious from the fact that in each of the past six years, our state has spent more money per mile on road improvements than any other state.

题目:

Which of the following, if true, most seriously undermines the reasoning in the spokesperson's argument?

选项:

A、In the spokesperson's state, spending on road improvements has been increasing more slowly over the past six years than it has in several other states. Adequacy of a state's road system is generally less important to a businessperson considering doing business there than is the availability of qualified employees.
B、Over the past six years, numerous businesses have left the spokesperson's state, but about as many businesses have moved into the state.
C、In general, the number of miles of road in a state's road system depends on both the area and the population of the state.
D、Only states with seriously inadequate road systems need to spend large amounts of money on road improvements.

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.
