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：
The last sentence in the passage serves primarily to
选项:
A、suggest that Krontiris’s work is not representative of recent trends among feminist scholars
B、undermine the argument that literate women of the Renaissance sought to oppose social constraints imposed on them
C、show a way in which Krontiris’s work illustrates a “cautiously optimistic” assessment of Renaissance women’s achievements
D、summarize Krontiris’s view of the effect of literacy on the lives of upper- and middle-class Renaissance women
E、illustrate the way in which Krontiris’s study differs from the studies done by Burckhardt and Kelly

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?
