(This passage was excerpted from materialpublished in 1993.)

    Like many other industries, the travel industry is under increasing pressure to expand globally in order to keep pace with its corporate customers, who have globalized their operations in response to market pressure, competitor actions, and changing supplier relations. But it is difficult for service organizations to globalize. Global expansion through acquisition is usually expensive, and expansion through internal growth is time-consuming and sometimes impossible in markets that are not actively growing. Some service industry companies, in fact, regard these traditional routes to global expansion as inappropriate for service industries because of their special need to preserve local responsiveness through local presence and expertise. One travel agency has eschewed the traditional route altogether. A survivor of the changes that swept the travel industry as a result of the deregulation of the airlines in 1978—changes that included dramatic growth in the corporate demand for travel services, as well as extensive restructuring and consolidation within the travel industry— this agency adopted a unique structure for globalization. Rather than expand by attempting to develop its own offices abroad, which would require the development of local travel management expertise sufficient to capture foreign markets, the company solved its globalization dilemma effectively by forging alliances with the best foreign partners it could find. The resulting cooperative alliance of independent agencies now comprises 32 partners spanning 37 countries.

题目:

The passage suggests that one of the effects of the deregulation of the airlines was

选项:

A、a decline in the services available to noncommercial travelers
B、a decrease in the size of the corporate travel market
C、a sharp increase in the number of cooperative alliances among travel agencies
D、increased competition in a number of different service industries
E、the merging of some companies within the travel industry

题目:

The prairie vole, a small North American grassland rodent, breeds year-round, and a group of voles living together consists primarily of an extended family, often including two or more litters.  Voles commonly live in large groups from late autumn through winter; from spring through early autumn, however, most voles live in far smaller groups.  The seasonal variation in group size can probably be explained by a seasonal variation in mortality among young voles.
 
Which of the following, if true, provides the strongest support for the explanation offered?

选项:

A、It is in the spring and early summer that prairie vole communities generally contain the highest proportion of young voles.
B、Prairie vole populations vary dramatically in size from year to year.
C、The prairie vole subsists primarily on broad-leaved plants that are abundant only in spring.
D、Winters in the prairie voles' habitat are often harsh, with temperatures that drop well below freezing.
E、Snakes, a major predator of young prairie voles, are active only from spring through early autumn.

E

题目:

In the country of Marut, the Foreign Trade Agency’s records were reviewed in 1994 in light of information then newly available about neighboring Goro. The review revealed that in every year since 1963, the agency’s projection of what Goro’s gross national product (GNP) would be five years later was a serious underestimate. The review also revealed that in every year since 1963, the agency estimated Goro’s GNP for the previous year—a Goro state secret—very accurately.

Of the following claims, which is most strongly supported by the statements given?

选项:

A、Goro’s GNP fluctuated greatly between 1963 and 1994.
B、Prior to 1995, Goro had not released data intended to mislead the agency in making its five-year projections.
C、The amount by which the agency underestimated the GNP it projected for Goro tended to increase over time.
D、Even before the new information came to light, the agency had reason to think that at least some of the five-year projections it had made were inaccurate.
E、The agency’s five-year projections of Goro’s GNP had no impact on economic planning in Marut.

题目:

Between 1980 and 2000 the sea otter population of the Aleutian Islands declined precipitously. There were no signs of disease or malnutrition, so there was probably an increase in the number of otters being eaten by predators. Orcas will eat otters when seals, their normal prey, are unavailable, and the Aleutian Islands seal population declined dramatically in the 1980s. Therefore, orcas were most likely the immediate cause of the otter population decline.

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

选项:

A、The population of sea urchins, the main food of sea otters, has increased since the sea otter population declined.
B、Seals do not eat sea otters, nor do they compete with sea otters for food.
C、Most of the surviving sea otters live in a bay that is inaccessible to orcas.
D、The population of orcas in the Aleutian Islands has declined since the 1980s.
E、An increase in commercial fishing near the Aleutian Islands in the 1980s caused a slight decline in the population of the fish that seals use for food.

题目:

Proposal:  Carbon dioxide and methane in the atmosphere block the escape of heat into space.  So emission of these "greenhouse" gases contributes to global warming.  In order to reduce global warming, emission of greenhouse gases needs to be reduced.  Therefore, the methane now emitted from open landfills should instead be burned to produce electricity.
 
Objection:  The burning of methane generates carbon dioxide that is released into the atmosphere.
 
Which of the following, if true, most adequately counters the objection made to the proposal?

选项:

A、Every time a human being or other mammal exhales, there is some carbon dioxide released into the air.
B、The conversion of methane to electricity would occur at a considerable distance from the landfills.
C、The methane that is used to generate electricity would generally be used as a substitute for a fuel that does not produce any greenhouse gases when burned.
D、Methane in the atmosphere is more effective in blocking the escape of heat from the Earth than is carbon dioxide.
E、The amount of methane emitted from the landfills could be reduced if the materials whose decomposition produces methane were not discarded, but recycled.

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?

A photography dealer ordered 60 Model X cameras to be sold for $250 each, which represents a 20 percent markup over the dealer's initial cost for each camera. Of the cameras ordered, 6 were never sold and were returned to the manufacturer for a refund of 50 percent of the dealer's initial cost. What was the dealer's approximate profit or loss as a percent of the dealer's initial cost for the 60 cameras?
