Line Linda Kerber argued in the mid-1980s that after
the American Revolution (1775–1783), an ideology
of “republican motherhood” resulted in a surge of
educational opportunities for women in the United
(5) States. Kerber maintained that the leaders of
the new nation wanted women to be educated in
order to raise politically virtuous sons. A virtuous
citizenry was considered essential to the success
of the country's republican form of government;
(10) virtue was to be instilled not only by churches and
schools, but by families, where the mother's role
was crucial. Thus, according to Kerber, motherhood
became pivotal to the fate of the republic, providing
justification for an unprecedented attention to female
(15) education.
Introduction of the “republican motherhood”
thesis dramatically changed historiography. Prior
to Kerber's work, educational historians barely
mentioned women and girls; Thomas Woody's
(20) 1929 work is the notable exception. Examining
newspaper advertisements for academies, Woody
found that educational opportunities increased for
both girls and boys around 1750. Pointing to “An
Essay on Woman” (1753) as reflecting a shift in
(25) view, Woody also claimed that practical education
for females had many advocates before the
Revolution. Woody's evidence challenges the notion
that the Revolution changed attitudes regarding
female education, although it may have accelerated
(30) earlier trends. Historians’ reliance on Kerber's
“republican motherhood” thesis may have obscured
the presence of these trends, making it difficult
to determine to what extent the Revolution really
changed women's lives.

题目：

The passage suggests that Woody would have agreed with which of the following claims regarding “An Essay on Woman”?

选项:

A、It expressed attitudes concerning women's education that were reflected in new educational opportunities for women after 1750.
B、It persuaded educators to offer greater educational opportunities to women in the 1750s.
C、It articulated ideas about women's education that would not be realized until after the American Revolution.
D、It offered one of the most original arguments in favor of women's education in the United States in the eighteenth century.
E、It presented views about women's education that were still controversial in Woody's own time.

答案:

A

题目：

Loss of the Gocha mangrove forests has caused coastal erosion, reducing fish populations and requiring the Gocha Fishing Cooperative (GFC) to partially fund dredging and new shore facilities. However, as part of its subsidiary businesses, the GFC has now invested in a program to replant significant parts of the coast with mangrove trees. Given income from a controlled harvest of wood with continuing replanting, the mangrove regeneration effort makes it more likely that the cooperative will increase its net income.

Which of the following, if true, would most strengthen the argument that mangrove replanting will increase the Gocha cooperative's net income?

选项:

A、The cost of dredging and shore facilities was shared with the local government.
B、The GFC will be able to hire local workers to assist with the mangrove replanting.
C、The GFC derives 10 percent of its revenue from salt-production facilities in an area previously cleared of mangroves.
D、Mangrove forests tend to increase the commercial fish populations in coastal fishing grounds.
E、A controlled harvesting of mangrove wood by the GFC would have little effect on coastal erosion.

D

题目：

Printwell's Ink Jet Division manufactures ink-jet printers and the ink cartridges they use.  Sales of its ink-jet printers have increased.  Monthly revenues from those sales, however, have not increased, because competition has forced Printwell to cut the prices of its printers.  Unfortunately, Printwell has been unable to bring down the cost of manufacturing a printer.  Thus, despite the increase in printer sales, the Ink Jet Division must be providing the company with much smaller than it used to.
 
Which of the following, if true, most seriously weakens the argument?

选项:

A、Ink-jet printers in regular use frequently need new ink cartridges, and Printwell's printers only accept Printwell's ink cartridges.
B、Unlike some competing companies, Printwell sells all of its printers through retailers, and these retailers' costs account for a sizable proportion of the printers' ultimate retail price.
C、Some printer manufacturers have been forced to reduce the sale price of their ink-jet printers even more than Printwell has.
D、In the past year, no competing manufacturer of ink-jet printers has had as great an increase in unit sales of printers as Printwell has.
E、In the past year, sales of Printwell's ink-jet printers have increased more than sales of any other type of printer made by Printwell.

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

D

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.
