Which of the following most logically completes the argument below?

题目:

Voters commonly condemn politicians for being insincere, but politicians often must disguise their true feelings when they make public statements. If they expressed their honest views—about, say, their party’s policies—then achieving politically necessary compromises would be much more difficult. Clearly, the very insincerity that people decry shows that our government is functioning well.

Which of the following, if true, most seriously undermines this reasoning?

选项:

A、Achieving political compromises is not all that is necessary for the proper functioning of a government.
B、Some political compromises are not in the best long-term interest of the government.
C、Voters often judge politicians by criteria other than the sincerity with which they express their views.
D、A political party’s policies could turn out to be detrimental to the functioning of a government.
E、Some of the public statements made by politicians about their party’s policies could in fact be sincere.

题目:

Birds have been said to be descended from certain birdlike dinosaur species with which they share distinctive structural features. The fossil record, however, shows that this cannot be so, since there are bird fossils that are much older than the earliest birdlike dinosaur fossils that have been found.

Which of the following is an assumption on which the argument relies?

选项:

A、The birdlike dinosaurs have no living descendants.
B、There are no flightless dinosaur species that have the distinctive structural features shared by birds and birdlike dinosaurs.
C、There are no birdlike dinosaur fossils that are older than the bird fossils but have not yet been unearthed.
D、It could not have been the case that some birds were descended from one of the birdlike dinosaur species and other birds from another.
E、Birds cannot have been descended from dinosaur species with which the birds do not share the distinctive structural features.

题目:

Aroca City currently funds its public schools through taxes on property.  In place of this system, the city plans to introduce a sales tax of three percent on all retail sales in the city.  Critics protest that three percent of current retail sales falls short of the amount raised for schools by property taxes.  The critics are correct on this point.  Nevertheless, implementing the plan will probably not reduce the money going to Aroca's schools.  Several large retailers have selected Aroca City as the site for huge new stores, and these are certain to draw large numbers of shoppers from neighboring municipalities, where sales are taxed at rates of six percent and more.  In consequence, retail sales in Aroca City are bound to increase substantially.
 
In the argument given, the two potions in boldface play which of the following roles?

选项:

A、The first is an objection that has been raised against a certain plan; the second is a prediction that, if accurate, undermines the force of that objection.
B、The first is a criticism, endorsed by the argument, of a funding plan; the second is a point the argument makes in favor of adopting an alternative plan.
C、The first is a criticism, endorsed by the argument, of a funding plan; the second is the main reason cited by the argument for its endorsement of the criticism.
D、The first is a claim that the argument seeks to refute; the second is the main point used by the argument to show that the claim is false.
E、The first is a claim that the argument accepts with certain reservations; the second presents that claim in a rewarding that is not subject to those reservations.

文章:

    In mid-February 1917 a women's movement independent of political affiliation erupted in Line New York City, the stronghold of the Socialist party in the United states. Protesting against the high cost of living, thousands of women refused to buy chickens, fish, and vegetables. The boycott shut down much of the City's foodstuffs marketing for two weeks, riveting public attention on the issue of food prices, which had increased partly as a result of increased exports of food to Europe that had been occurring since the outbreak of the First World War.

    By early 1917 the Socialist party had established itself as a major political presence in New York City. New York Socialists, whose customary spheres of struggle were electoral work and trade union organizing, seized the opportunity and quickly organized an extensive series of cost-of-living protests designed to direct the women's movement toward Socialist goals. Underneath the Socialists' brief commitment to cost-of-living organizing lay a basic indifference to the issue itself. While some Socialists did view price protests as a direct step toward socialism, most Socialists ultimately sought to divert the cost-of-living movement into alternative channels of protest. Union organizing, they argued, was the best method through which to combat the high cost of living. For others, cost-of-living or oganizing was valuable insofar as it led women into the struggle for suffrage, and similarly, the suffrage struggle was valuable insofar as it moved United States society one step closer to socialism.

    Although New York's Socialists saw the cost-of-living issue as, at best ,secondary or tertiary to the real task at hand, the boycotters, by sharp contrast, joined the price protest movement out of an urgent and deeply felt commitment to the cost-of-living issue. A shared experience of swiftly declining living standards caused by rising food prices drove these women to protest. Consumer organizing spoke directly to their daily lives and concerns; they saw cheaper food as a valuable end in itself. Food price protests were these women's way of organizing at their own workplace, as workers whose occupation was shopping and preparing food for their families.

题目:

Which of the following best states the function of the passage as a whole?

选项:

A、To contrast the views held by the Socialist party and by the boycotting women of New York City on the cost-of-living issue
B、To analyze the assumptions underlying oppos-ing viewpoints within the New York Socialist party of 1917
C、To provide a historical perspective on different approaches to the resolution of the cost-of-living issue.
D、To chronicle the sequence of events that led to the New York Socialist party's emergence as a political power
E、To analyze the motivations behind the Socialist party's involvement in the women's suffrage movement.

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.

What was the dealer's approximate profit or loss as a percent of the dealer's initial cost for the 60 cameras?
