题目：

Mourdet Winery:  Danville Winery's new wine was introduced to compete with our most popular wine, which is sold in a distinctive tall, black bottle.  Danville uses a similar bottle.  Thus, it is likely that many customers intending to buy our wine will mistakenly buy theirs instead.
 
Danville Winery:  Not so.  The two bottles can be readily distinguished:  the label on ours, but not on theirs, is gold colored.
 
Which of the following, if true, most undermines Danville Winery's response?

选项:

A、Gold is the background color on the label of many of the wines produced by Danville Winery.
B、When the bottles are viewed side by side, Danville Winery's bottle is perceptibly taller than Mourdet Winery's.
C、Danville Winery, unlike Mourdet Winery, displays its wine's label prominently in advertisements.
D、It is common for occasional purchasers to buy a bottle of wine on the basis of a general impression of the most obvious feature of the bottle.
E、Many popular wines are sold in bottles of a standard design.

D

文章：

Two works published in 1984 demonstrate contrasting approaches to writing the history of United States women. Buel and Buel’s biography of Mary Fish (1736–1818) makes little effort to place her story in the context of recent historiography on women. Lebsock, meanwhile, attempts not only to write the history of women in one southern community, but also to redirect two decades of historiographical debate as to whether women gained or lost status in the nineteenth century as compared with the eighteenth century. Although both books offer the reader the opportunity to assess this controversy regarding women’s status, only Lebsock’s deals with it directly. She examines several different aspects of women’s status, helping to refine and resolve the issues. She concludes that while women gained autonomy in some areas, especially in the private sphere, they lost it in many aspects of the economic sphere. More importantly, she shows that the debate itself depends on frame of reference: in many respects, women lost power in relation to men, for example, as certain jobs (delivering babies, supervising schools) were taken over by men. Yet women also gained power in comparison with their previous status, owning a higher proportion of real estate, for example. In contrast, Buel and Buel’s biography provides ample raw material for questioning the myth, fostered by some historians, of a colonial golden age in the eighteenth century but does not give the reader much guidance in analyzing the controversy over women’s status.

The passage suggests that Lebsock believes that compared to nineteenth-century American women, eighteenth-century American women were

选项:

A、in many respects less powerful in relation to menmore likely to own real estate
B、generally more economically independent
C、more independent in conducting their private lives
D、less likely to work as school superintendents

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.
