题目:

When a new restaurant, Martin's Cafe, opened in Riverville last year, many people predicted that business at the Wildflower Inn, Riverville's only other restaurant, would suffer from the competition.  Surprisingly, however, in the year since Martin's Cafe opened, the average number of meals per night served at the Wildflower Inn has increased significantly.
 
Which of the following, if true, most helps to explain the increase?

选项:

A、Unlike the Wildflower Inn, Martin's Cafe serves considerably more meals on weekends than it does on weekdays.
B、Most of the customers of Martin's Cafe had never dined in Riverville before this restaurant opened, and on most days Martin's Cafe attracts more customers than it can seat.
C、The profit per meal is higher, on average, for meals served at Martin's Cafe than for those served at the Wildflower Inn.
D、The Wildflower Inn is not open on Sundays, and therefore Riverville residents who choose to dine out on that day must either eat at Martin's Cafe or go to neighboring towns to eat.
E、A significant proportion of the staff at Martin's Cafe are people who formerly worked at the Wildflower Inn and were hired away by the owner of Martin's Cafe.

文章:

In a new book about the antiparty feeling of the early political leaders of the United States, Ralph Ketcham argues that the first six Presidents differed decisively from later Presidents because the first six held values inherited from the classical humanist tradition of eighteenth-century England. In this view, government was designed not to satisfy the private desires of the people but to make them better citizens; this tradition stressed the disinterested devotion of political leaders to the public good.  Justice, wisdom, and courage were more important qualities in a leader than the ability to organize voters and win elections.  Indeed, leaders were supposed to be called to office rather than to run for office.  And if they took up the burdens of public office with a sense of duty, leaders also believed that such offices were naturally their due because of their social preeminence or their contributions to the country.  Given this classical conception of leadership, it is not surprising that the first six Presidents condemned political parties.  Parties were partial by definition, self-interested, and therefore serving something other than the transcendent public good.
 
Even during the first presidency (Washington's), however, the classical conception of virtuous leadership was being undermined by commercial forces that had been gathering since at least the beginning of the eighteenth century.  Commerce--its profit-making, its self-interestedness, its individualism--became the enemy of these classical ideals.  Although Ketcham does not picture the struggle in quite this way, he does rightly see Jackson's tenure (the seventh presidency) as the culmination of the acceptance of party, commerce, and individualism.  For the Jacksonians, nonpartisanship lost its relevance, and under the direction of Van Buren, party gained a new legitimacy.  The classical ideals of the first six Presidents became identified with a privileged aristocracy, an aristocracy that had to be overcome in order to allow competition between opposing political interests.  Ketcham is so strongly committed to justifying the classical ideals, however, that he underestimates the advantages of their decline.  For example, the classical conception of leadership was incompatible with our modern notion of the freedoms of speech and press, freedoms intimately associated with the legitimacy of opposing political parties.

题目:

It can be inferred that the author of the passage would be most likely to agree that modern views of the freedoms of speech and press are

选项:

A、values closely associated with the beliefs of the aristocracy of the early United States
B、political rights less compatible with democracy and individualism than with classical ideals
C、political rights uninfluenced by the formation of opposing political parties
D、values not inherent in the classical humanist tradition of eighteenth-century England
E、values whose interpretation would have been agreed on by all United States Presidents

题目:

Escalating worldwide demand for corn has led to a sharp increase in the market price of corn, and corn prices are likely to remain high.  Corn is extensive used as feed for livestock, and because profit margins are tight in the livestock business, many farmers are expected to leave the business.  With fewer suppliers, meat prices will surely rise.  Nonetheless, observers expect an immediate short-term decrease in meat prices.
 
Which of the following, if true, most helps to justify the observers' expectation?

选项:

A、The increase in corn prices is due more to a decline in the supply of corn than to a growth in demand for it.
B、Generally, farmers who are squeezed out of the livestock business send their livestock to market much earlier than they otherwise would.
C、Some people who ate meat regularly in the past are converting to diets that include little or no meat.
D、As meat prices rise, the number of livestock producers is likely to rise again.
E、Livestock producers who stay in the business will start using feed other than corn more extensively than they did in the past.

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.
