题目：

Thyrian lawmaker: Thyria’s Cheese Importation Board inspects all cheese shipments to Thyria and rejects shipments not meeting specified standards. Yet only 1 percent is ever rejected. Therefore, since the health consequences and associated economic costs of not rejecting that 1 percent are negligible, whereas the board’s operating costs are considerable, for economic reasons alone the board should be disbanded.

Consultant: I disagree. The threat of having their shipments rejected deters many cheese exporters from shipping substandard product.

The consultant responds to the lawmaker’s argument by

选项:

A、rejecting the lawmaker’s argument while proposing that the standards according to which the board inspects imported cheese should be raised
B、providing evidence that the lawmaker’s argument has significantly overestimated the cost of maintaining the board
C、objecting to the lawmaker’s introducing into the discussion factors that are not strictly economic
D、pointing out a benefit of maintaining the board, which the lawmaker’s argument has failed to consider
E、shifting the discussion from the argument at hand to an attack on the integrity of the cheese inspectors

D

题目：

Until she was given tenure at the college, Susan was considered an average teacher. It is clear that if her receiving tenure was justified, then Susan was much better than average or very loyal. Soon after she was awarded tenure, however, it was shown that she was not better than average. Thus, one is forced to conclude that Susan must have been very loyal.
Which one of the following states an assumption upon which the argument depends?

选项:

A、A. Susan being given tenure was justified.
B、B. Susan was a teacher at a college.
C、C. Giving tenure to someone who is very loyal would be justified.

文章：

Line         In 1955 Maurice Duverger published The Political
  Role of Women, the first behavioralist, multinational
  comparison of women’s electoral participation ever to
  use election data and survey data together.
(5) His study analyzed women’s patterns of voting,
  political candidacy, and political activism in four
  European countries during the first half of the
  twentieth century. Duverger’s research findings
  were that women voted somewhat less frequently
(10) than men (the difference narrowing the longer
  women had the vote) and were slightly more
  conservative.
       Duverger’s work set an early standard for the
  sensitive analysis of women’s electoral activities.
(15) Moreover, to Duverger’s credit, he placed his
  findings in the context of many of the historical
  processes that had shaped these activities.
  However, since these contexts have changed over
  time, Duverger’s approach has proved more durable
(20) than his actual findings. In addition, Duverger’s
  discussion of his findings was hampered by his failure
  to consider certain specific factors important to
  women’s electoral participation at the time he
  collected his data: the influence of political regimes,
(25) the effects of economic factors, and the
  ramifications of political and social relations between
  women and men. Given this failure, Duverger’s
  study foreshadowed the enduring limitations of the
  behavioralist approach to the multinational study of
(30) women’s political participation.


题目：

Which of the following characteristics of a country is most clearly an example of a factor that Duverger, as described in the passage, failed to consider in his study?

选项:

A、A large population
B、A predominantly Protestant population
C、A predominantly urban population
D、A one-party government
E、Location in the heart of Europe

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?
