文章：

Line         Jacob Burckhardt’s view that Renaissance
  European women “stood on a footing of perfect
  equality” with Renaissance men has been repeatedly
  cited by feminist scholars as a prelude to their
(5) presentation of rich historical evidence of women’s
  inequality. In striking contrast to Burckhardt, Joan
  Kelly in her famous 1977 essay, “Did Women Have
  a Renaissance?” argued that the Renaissance was
  a period of economic and social decline for women
(10) relative both to Renaissance men and to medieval
  women. Recently, however, a significant trend
  among feminist scholars has entailed a rejection
  of both Kelly’s dark vision of the Renaissance and
  Burckhardt’s rosy one. Many recent works by these
(15) scholars stress the ways in which differences
  among Renaissance women—especially in terms
  of social status and religion—work to complicate
  the kinds of generalizations both Burckhardt and
  Kelly made on the basis of their observations about
(20) upper-class Italian women.
       The trend is also evident, however, in works
  focusing on those middle- and upper-class
  European women whose ability to write gives them
  disproportionate representation in the historical
(25) record. Such women were, simply by virtue of
  their literacy, members of a tiny minority of the
  population, so it is risky to take their descriptions of
  their experiences as typical of “female experience”
  in any general sense. Tina Krontiris, for example, in
(30) her fascinating study of six Renaissance women
  writers, does tend at times to conflate “women” and
  “women writers,” assuming that women’s gender,
  irrespective of other social differences, including
  literacy, allows us to view women as a homogeneous
(35) social group and make that group an object of
  analysis. Nonetheless, Krontiris makes a significant
  contribution to the field and is representative of
  those authors who offer what might be called a
  cautiously optimistic assessment of Renaissance
(40) women’s achievements, although she also stresses
  the social obstacles Renaissance women faced
  when they sought to raise their “oppositional
  voices.” Krontiris is concerned to show women
  intentionally negotiating some power for themselves
(45) (at least in the realm of public discourse) against
  potentially constraining ideologies, but in her sober
  and thoughtful concluding remarks, she suggests
  that such verbal opposition to cultural stereotypes
  was highly circumscribed; women seldom attacked
(50) the basic assumptions in the ideologies that
  oppressed them.


题目：

According to the passage, Krontiris’s work differs from that of the scholars mentioned in line 12 in which of the following ways?

选项:

A、Krontiris’s work stresses the achievements of Renaissance women rather than the obstacles to their success.
B、Krontiris’s work is based on a reinterpretation of the work of earlier scholars.
C、Krontiris’s views are at odds with those of both Kelly and Burkhardt.
D、Krontiris’s work focuses on the place of women in Renaissance society.
E、Krontiris’s views are based exclusively on the study of a privileged group of women.

E

题目：

Regulations will not allow a pesticide that is toxic to humans to be used inside houses unless the pesticide will dissipate completely from the air within eight hours after its application.  One test that pesticide manufacturers standardly use to determine how quickly anti-termite pesticides dissipate involves spraying the pesticides on the walls of room-sized plywood boxes and then timing its dissipation.
 
Which of the following would it be most useful to know in order to evaluate whether a dissipation time of just under eight hours on the manufacturers' test indicates that an anti-termite pesticide that is toxic to humans obeys regulations for use in houses?

选项:

A、Whether anti-termite pesticides dissipate more slowly in furnished rooms than in plywood boxes
B、Whether people who apply anti-termite pesticide standardly wear protective equipment that prevents them from being exposed to the pesticide
C、Whether people whose house is being treated with anti-termite pesticide generally know that they should remain out of their house during the hours immediately after the pesticide's application
D、Whether there are anti-termite pesticides that are toxic to humans that, when subjected to the manufacturers' test, dissipate completely from the air in the boxes in well under eight hours
E、Whether anti-termite pesticides that are not toxic to humans tend to take longer to dissipate than those that are toxic

文章：

    In a 1984 book, Claire C. Robertson argued that, before colonialism, age was a more important indicator of status and authority than gender in Ghana and in Africa generally. British colonialism imposed European-style maledominant notions upon more egalitarian local situations to the detriment of women generally, and gender became a defining characteristic that weakened women's power and authority.

    Subsequent research in Kenya convinced Robertson that she had overgeneralized about Africa. Before colonialism, gender was more salient in central Kenya than it was in Ghana, although age was still crucial in determining authority. In contrast with Ghana, where women had traded for hundreds of years and achieved legal majority (not unrelated phenomena), the evidence regarding central Kenya indicated that women were legal minors and were sometimes treated as male property, as were European women at that time. Factors like strong patrilinearity and patrilocality, as well as women's inferior land rights and lesser involvement in trade, made women more dependent on men than was generally the case in Ghana. However, since age apparently remained the overriding principle of social organization in central Kenya, some senior women had much authority. Thus, Robertson revised her hypothesis somewhat, arguing that in determining authority in precolonial Africa age was a primary principle that superseded gender to varying degrees depending on the situation.

题目：

The passage indicates that Robertson's research in Kenya caused her to change her mind regarding which of the following?

选项:

A、Whether age was the prevailing principle of social organization in Kenya before colonialism
B、Whether gender was the primary determinant of social authority in Africa generally before colonialism
C、Whether it was only after colonialism that gender became a significant determinant of authority in Kenyan society
D、Whether age was a crucial factor determining authority in Africa after colonialism
E、Whether British colonialism imposed European-style male-dominant notions upon local situations in Ghana

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?
