题目:

On several Native American reservations, comparisons of buffalo herds versus domesticated cattle herds have shown that the buffalo herds are far superior meat producers. In addition, native tribes use every part of the buffalo as they did before wild buffalo were almost destroyed on this continent. Therefore, domesticated cattle herds should be replaced with buffalo herds as soon as possible.
Each of the following, if true, would weaken the argument EXCEPT:

选项:

A、A. Only Native American tribes use part of the buffalo other than the meat.
B、B. Not everyone likes the taste of buffalo as much as they like the taste of regular beef.
C、C. Cattle ranchers may not know how to raise buffalo.
D、D. Professional chefs need time to develop meals that include buffalo.
E、E. Cattle ranches may not have the type of grazing land required for buffalo.

文章:

Historians have identified two dominant currents in the Russian women's movement of the late tsarist period.  "Bourgeois" feminism, so called by its more radical opponents, emphasized "individualist" feminist goals such as access to education, career opportunities, and legal equality.  "Socialist" feminists, by contrast, emphasized class, rather than gender, as the principal source of women's inequality and oppression, and socialist revolution, not legal reform, as the only road to emancipation and equality.

 

However, despite antagonism between bourgeois feminists and socialist feminists, the two movements shared certain underlying beliefs.  Both regarded paid labor as the principal means by which women might attain emancipation:  participation in the workplace and economic self-sufficiency, they believed, would make women socially useful and therefore deserving of equality with men.  Both groups also recognized the enormous difficulties women faced when they combined paid labor with motherhood.  In fact, at the First All-Russian Women's Congress in 1908, most participants advocated maternity insurance and paid maternity leave, although the intense hostility between some socialists and bourgeois feminists at the Congress made it difficult for them to recognize these areas of agreement.  Finally, socialist feminists and most bourgeois feminists concurred in subordinating women's emancipation to what they considered the more important goal of liberating the entire Russian population from political oppression, economic backwardness, and social injustice.

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.
