文章:

    For many years, theoretical economists characterized humans as rational beings relentlessly bent on maximizing purely selfish reward. Results of an experimental economics study appear to contradict this view, however. In the "Ultimatum Game," two subjects, who cannot exchange information, are placed in separate rooms. One is randomly chosen to propose how a sum of money, known to both, should be shared between them; only one offer, which must be accepted or rejected without negotiation, is allowed.

    If, in fact, people are selfish and rational, then the proposer should offer the smallest possible share, while the responder should accept any offer, no matter how small: after all, even one dollar is better than nothing. In numerous trials, however, two-thirds of the offers made were between 40 and 50 percent; only 4 percent were less than 20 percent. Among responders, more than half who were offered less than 20 percent rejected the offer. Behavior in the game did not appreciably depend on the players' sex, age, or education. Nor did the amount of money involved play a significant role: for instance, in trials of the game that were conducted in Indonesia, the sum to be shared was as much as three times the subjects' average monthly income, and still responders refused offers that they deemed too small.

题目:

The primary purpose of the passage is to

选项:

A、provide evidence in support of the view that human beings are essentially rational and selfish
B、use a particular study to challenge the argument that the economic behavior of human beings may be motivated by factors other than selfishness
C、compare certain views about human nature held by theoretical economists with those held by experimental economists
D、describe a study that apparently challenges theoretical economists' understanding of human economic behavior
E、suggest that researchers may have failed to take into account the impact of certain noneconomic factors in designing a study of human economic behavior

文章:

Line         Current feminist theory, in validating women’s own
  stories of their experience, has encouraged scholars
  of women’s history to view the use of women’s oral
  narratives as the methodology, next to the use of
(5) women’s written autobiography, that brings historians
  closest to the “reality” of women’s lives. Such
  narratives, unlike most standard histories, represent
  experience from the perspective of women, affirm
  the importance of women’s contributions, and furnish
(10) present-day women with historical continuity that is
  essential to their identity, individually and collectively.
       Scholars of women’s history should, however, be
  as cautious about accepting oral narratives at face
  value as they already are about written memories.
(15) Oral narratives are no more likely than are written
  narratives to provide a disinterested commentary on
  events or people. Moreover, the stories people tell to
  explain themselves are shaped by narrative devices
  and storytelling conventions, as well as by other
(20) cultural and historical factors, in ways that the
  storytellers may be unaware of. The political rhetoric
  of a particular era, for example, may influence
  women’s interpretations of the significance of their
  experience. Thus a woman who views the Second
(25) World War as pivotal in increasing the social
  acceptance of women’s paid work outside the home
  may reach that conclusion partly and unwittingly
  because of wartime rhetoric encouraging a positive
  view of women’s participation in such work.


题目:

The author of the passage would be most likely to make which of the following recommendations to scholars of women’s history?

选项:

A、They should take into account their own life experiences when interpreting the oral accounts of women’s historical experiences.
B、They should assume that the observations made in women’s oral narratives are believed by the intended audience of the story.
C、They should treat skeptically observations reported in oral narratives unless the observations can be confirmed in standard histories.
D、They should consider the cultural and historical context in which an oral narrative was created before arriving at an interpretation of such a narrative.
E、They should rely on information gathered from oral narratives only when equivalent information is not available in standard histories.

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?
