题目:

Jay: Of course there are many good reasons to support the expansion of preventive medical care, but arguments claiming that it will lead to greater societal economic gains are misguided. Some of the greatest societal expenses arise from frequent urgent-care needs for people who have attained a long life due to preventive care.

Sunil: Your argument fails because you neglect economic gains outside the health care system: society suffers an economic loss when any of its productive members suffer preventable illnesses.

Sunil's response to Jay makes which of the following assumptions?

选项:

A、
A. Those who receive preventive care are not more likely to need urgent care than are those who do not receive preventive care.
B、
B. Jay intends the phrase “economic gains” to refer only to gains accruing to institutions within the health care system.
C、
C. Productive members of society are more likely than others to suffer preventable illnesses.
D、
D. The economic contributions of those who receive preventive medical care may outweigh the economic losses caused by preventive care.
E、
E. Jay is incorrect in stating that patients who receive preventive medical care are long-lived.

D

文章:

In a new book about the antiparty feeling of the early political leaders of the United States, Ralph Ketch am 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 Ketch am 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 aristocrat 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 modem notion of the freedoms of speech and press, freedoms intimately associated with the legitimacy of opposing political patties.

题目:

Which of the following best describes the attitude of the first six Presidents toward political parties as it is discussed in the passage?

选项:

A、Political parties were essential to the notions of democracy on which the United States government was based. 
B、Personal character in leadership was as important as affiliation with a political party. 
C、Political parties were one way to ensure that government could meet the needs of all citizens. 
D、Political parties, though undesirable, were inevitable in a democratic political system. 
E、Political parties represented opposing political interests rather than the general public good.

E

文章:

Line In current historiography, the picture of a consistent,
unequivocal decline in women’s status with the advent
of capitalism and industrialization is giving way to an
analysis that not only emphasizes both change (whether
(5) improvement or decline) and continuity but also
accounts for geographical and occupational variation.
The history of women’s work in English farmhouse
cheese making between 1800 and 1930 is a case in
point. In her influential Women Workers and the Industrial
(10) Revolution (1930), Pinchbeck argued that the agricultural
revolution of the eighteenth and early nineteenth
centuries, with its attendant specialization and enlarged
scale of operation, curtailed women’s participation in
the business of cheese production. Earlier, she
(15) maintained, women had concerned themselves with
feeding cows, rearing calves, and even selling the
cheese in local markets and fairs. Pinchbeck thought
that the advent of specialization meant that women’s
work in cheese dairying was reduced simply to
(20) processing the milk. “Dairymen” (a new social category)
raised and fed cows and sold the cheese through
factors, who were also men. With this narrowing of the
scope of work, Pinchbeck believed, women lost
business ability, independence, and initiative.
(25) Though Pinchbeck portrayed precapitalist,
preindustrial conditions as superior to what followed,
recent scholarship has seriously questioned the notion
of a golden age for women in precapitalist society. For
example, scholars note that women’s control seldom
(30) extended to the disposal of the proceeds of their
work. In the case of cheese, the rise of factors may
have compromised women’s ability to market cheese
at fairs. But merely selling the cheese did not
necessarily imply access to the money: Davidoff cites
(35) the case of an Essex man who appropriated all but a
fraction of the money from his wife’s cheese sales.
By focusing on somewhat peripheral operations,
moreover, Pinchbeck missed a substantial element
of continuity in women’s participation: throughout the
(40) period women did the central work of actually
making cheese. Their persistence in English cheese
dairying contrasts with women’s early disappearance
from arable agriculture in southeast England and
from American cheese dairying. Comparing these
(45) three divergent developments yields some reasons
for the differences among them. English cheese-
making women worked in a setting in which cultural
values, agricultural conditions, and the nature of
their work combined to support their continued
(50) participation. In the other cases, one or more of
these elements was lacking.

题目:

Until mow, only injectable vaccines against influenza have been available.  Parents are reluctant to subject children to the pain of injections, but adults, who are at risk of serious complications from influenza, are commonly vaccinated.  A new influenza vaccine, administered painlessly in a nasal spray, is effective for children.  However, since children seldom develop serious complications from influenza, no significant public health benefit would result from widespread vaccination of children using the nasal spray.
 
Which of the following is an assumption on which the argument depends?

选项:

A、Any person who has received the injectable vaccine can safely receive the nasal-spray vaccine as well.
B、The new vaccine uses the same mechanism to ward off influenza as jnjectable vaccines do.
C、The injectable vaccine is affordable for all adults.
D、Adults do not contract influenza primarily from children who have influenza.

题目:

It is illegal to advertise prescription medications in Hedland except in professional medical journals or by mail directly to physicians.  A proposed law would allow general advertising of prescription medications.  Opponents object that, in general, laypersons lack the specialized knowledge to evaluate such advertisements and might ask their physicians for inappropriate medications.  But since physicians have the final say as to whether to prescribe a medication for a patient, the objection provides no grounds for concern.
 
Which of the following would it be most useful to establish in order to evaluate the argument?

选项:

A、Whether nonprescription medications can interact with and block the action of any prescription medications that could be advertised to the general public
B、Whether most prescription medication advertisements directed at the general public would be advertisements for recently developed medications newly available by prescription
C、Whether prescription medication advertisements directed at the general public would appear on television and radio as well as in print
D、Whether physicians are more likely to pay attention to advertising directed to the general public than to advertising directed to physicians
E、Whether physicians are likely to succumb to pressure from patients to prescribe inappropriate medications

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?
