题目:

Male bowerbirds construct elaborately decorated nests, or bowers. Basing their judgment on the fact that different local populations of bowerbirds of the same species build bowers that exhibit different building and decorative styles, researchers have concluded that the bowerbirds' building styles are a culturally acquired, rather than a genetically transmitted, trait.

Which of the following, if true, would most strengthen the conclusion drawn by the researchers?

选项:

A、There are more common characteristics than there are differences among the bower-building styles of the local bowerbird population that has been studied most extensively.
B、Young male bowerbirds are inept at bower-building and apparently spend years watching their elders before becoming accomplished in the local bower style.
C、The bowers of one species of bowerbird lack the towers and ornamentation characteristic of the bowers of most other species of bowerbird.
D、Bowerbirds are found only in New Guinea and Australia, where local populations of the birds apparently seldom have contact with one another.
E、It is well known that the song dialects of some songbirds are learned rather than transmitted genetically.

文章:

Line Arboria is floundering in the global marketplace,
incurring devastating losses in market position and
profits. The problem is not Arboria's products, but
Arboria's trade policy. Arboria faces the prospect
(5) of continuing economic loss until Arborian business
and political leaders recognize the fundamental
differences between Arborian and foreign economic
systems. Today the key trade issue is not free trade
versus protectionism but diminishing trade versus
(10) expanding trade.
Arboria is operating with an obsolete trade policy,
an artifact of the mid-1940s when Arboria and
Whorfland dominated the global economy, tariffs
were the principal obstacle to trade, and Arborian
(15) supremacy was uncontested in virtually all industries.
In the intervening decades, economic circumstances
have shifted radically. Arborian trade policy has not.
Today, Arboria's trade policy seems paralyzed
by the relentless conflict between proponents of
(20) “free” and “fair” trade. The free traders argue that
Arborian markets should be open, and the movement
of goods and services across national borders
unrestrained. The fair traders assert that access to
Arborian markets should be restricted until Arborian
(25) businesses are granted equal access to foreign
markets. They contend that free trade is impossible
while other nations erect barriers to Arborian exports.
Both are correct: fair trade requires equal access
and equal access leads to free trade. But both sides
(30) base their positions on the same two outdated
premises:
1. Global commerce is conducted under the terms of
the General Agreement on Tariffs and Trade (GATT)
and dominated by Arboria and similar economic
(35) systems abroad.
2. Multilateral negotiations are the most effective way
to resolve pressing trade issues.
Both assumptions are wrong. The 40-year-old GATT
now covers less than 7 percent of global commerce.
(40) World trade is no longer dominated by the free-
trade economies; nearly 75 percent is conducted
by economic systems operating with principles at
odds with those of Arboria. Forging a multilateral
trade policy consensus among so many diverse
(45) economic systems has become virtually impossible.
And while multilateral talks drag on, Arboria misses
opportunities for trade expansion.

题目:

The author asserts which of the following about Arboria's trade policy?

选项:

A、A dramatic revision of Arboria's trade policy will be necessary unless Arborian manufacturers improve the quality of their goods.
B、The most crucial issue facing Arborian trade policymakers is that of free trade versus protectionism.
C、Arboria's current trade policy was essentially developed during the 1940s and has changed little since that time.
D、Arboria's trade policy is widely emulated throughout the world, to the extent that most international commerce is modeled on Arboria's principles.
E、Arboria's trade policy has evolved gradually over the last eighty years, constantly readjusting itself in response to shifts in global commerce.

(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

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.
