题目：

Politician: Hybrid cars use significantly less fuel per kilometer than nonhybrids. And fuel produces air pollution, which contributes to a number of environmental problems. Motorists can save money by driving cars that are more fuel efficient, and they will be encouraged to drive hybrid cars if we make them aware of that fact. Therefore, we can help reduce the total amount of pollution emitted by cars in this country by highlighting this advantage of hybrid cars.

Which of the following, if true, would most indicate a vulnerability of the politician’s argument?

选项:

A、People with more fuel-efficient cars typically drive more than do those with less fuel-efficient cars.
B、Not all air pollution originates from automobiles.
C、Hybrid cars have already begun to gain popularity.
D、Fuel-efficient alternatives to hybrid cars will likely become available in the future.
E、The future cost of gasoline and other fuel cannot be predicted with absolute precision or certainty.

题目：

Charcoal from a hearth site in Colorado, 2,000 miles south of Alaska, is known to be 11,200 years old.  Researchers reasoned that, since glaciers prevented human migration south from the Alaska-Siberia land bridge between 18,000 and 11,000 years ago, humans must have come to the Americas more than 18,000 years ago.
 
Which of the following pieces of new evidence would cast doubt on the conclusion drawn above?

选项:

A、Using new radiocarbon dating techniques, it was determined that the charcoal from the Colorado site was at least 11,400 years old.
B、Another campsite was found in New Mexico with remains dated at 16,000 years old.
C、A computer simulation of glacial activity showed that it would already have been impossible for humans to travel south overland from Alaska 18,500 years ago.
D、Using new radiocarbon dating techniques, it was proved that an ice-free corridor allowed passage south from the Alaska-Siberia land bridge at least 11,400 years ago.
E、Studies of various other hunting-gathering populations showed convincingly that, once the glaciers allowed passage, humans could have migrated from Alaska to Colorado in about 20 years.

文章：

Some historians contend that conditions in the United States during the Second World War gave rise to a dynamic wartime alliance between trade unions and the African American community, an alliance that advanced the cause of civil rights.  They conclude that the postwar demise of this vital alliance constituted a lost opportunity for the civil rights movement that followed the war.  Other scholars, however, have portrayed organized labor as defending all along the relatively privileged position of White workers relative to African American workers.  Clearly, these two perspectives are not easily reconcilable, but the historical reality is not reducible to one or the other.
 
Unions faced a choice between either maintaining the prewar status quo or promoting a more inclusive approach that sought for all members the right to participate in the internal affairs of unions, access to skilled and high-paying positions within the occupational hierarchy, and protection against management's arbitrary authority in the workplace.  While union representatives often voiced this inclusive ideal, in practice unions far more often favored entrenched interests.  The accelerating development of the civil rights movement following the Second World War exacerbated the unions' dilemma, forcing trade unionists to confront contradictions in their own practices.

According to the passage, the historians mentioned in the first highlighted portion of text and the scholars mentioned in the second highlighted portion disagree about the

选项:

A、contribution made by organized labor to the war effort during the Second World War
B、issues that union members considered most important during the Second World War
C、relationship between unions and African Americans during the Second World War

文章：

    In her account of unmarried women's experiences in colonial Philadelphia, Wulf argues that educated young women, particularly Quakers, engaged in resistance to patriarchal marriage by exchanging poetry critical of marriage, copying verse into their commonplace books. Wulf suggests that this critique circulated beyond the daughters of the Quaker elite and middle class, whose commonplace books she mines, proposing that Quaker schools brought it to many poor female students of diverse backgrounds.

    Here Wulf probably overstates Quaker schools' impact. At least three years' study would be necessary to achieve the literacy competence necessary to grapple with the material she analyzes. In 1765, the year Wulf uses to demonstrate the diversity of Philadelphia's Quaker schools, 128 students enrolled in these schools. Refining Wulf's numbers by the information she provides on religious affiliation, gender, and length of study, it appears that only about 17 poor non-Quaker girls were educated in Philadelphia's Quaker schools for three years or longer. While Wulf is correct that a critique of patriarchal marriage circulated broadly, Quaker schools probably cannot be credited with instilling these ideas in the lower classes. Popular literary satires on marriage had already landed on fertile ground in a multiethnic population that embodied a wide range of marital beliefs and practices. These ethnic and class-based traditions themselves challenged the legitimacy of patriarchal marriage.

题目：

The author of the passage implies which of the following about the poetry mentioned in the first paragraph?

选项:

A、Wulf exaggerates the degree to which young women from an elite background regarded the poetry as providing a critique of marriage.
B、The circulation of the poetry was confined to young Quaker women.
C、Young women copied the poetry into their commonplace books because they interpreted it as providing a desirable model of unmarried life.
D、The poetry's capacity to influence popular attitudes was restricted by the degree of literacy necessary to comprehend it.
E、The poetry celebrated marital beliefs and practices that were in opposition to patriarchal marriage.

D

题目：

In Kantovia, physicians' income comes from insurance companies, which require physicians to document their decisions in treating patients and to justify deviations from the companies' treatment guidelines. Ten years ago physicians were allowed more discretion. Most physicians believe that the companies' requirements now prevent them from spending enough time with patients. Yet the average amount of  time a patient spends with a physician during an office visit has actually increased somewhat over the last ten years.
 
Which of the following, if true, most helps to resolve the apparent discrepancy between physicians' perceptions and the change in the actual time spent?

选项:

A、Patients are more likely to be in a hurry nowadays and are less willing to wait a long time to see their physician.
B、Physicians today typically have a wider range of options in diagnosis and treatment to consider with the patient before prescribing.
C、Physicians are increasingly likely to work in group practices, sharing the responsibility of night and weekend work.
D、Most patients would rather trust their physicians than their insurance companies to make decisions about their treatment.
E、Since the insurance companies pay physicians a set amount for each office visit, it is to physicians' financial advantage to see as many Patients as possible.

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?
