多选题 Questions 8-10 are based on the following passage. Given the persistent and intransigent nature of the American race system, which proved quite impervious to black attacks,Line Du Bois in his speeches and writings moved (5) from one proposed solution to another, and the salience of various parts of his philoso- phy changed as his perceptions of the needs and strategies of black America shifted over time. Aloof and autonomous in his personal- (10) ity, Du Bois did not hesitate to depart markedly from whatever was the current mainstream of black thinking when he per- ceived that the conventional wisdom being enunciated by black spokesmen was proving (15) inadequate to the task of advancing the race. His willingness to seek different solutions often placed him well in advance of his con- temporaries, and this, combined with a strong-willed, even arrogant personality (20) made his career as a black leader essentially a series of stormy conflicts. Thus Du Bois first achieved his role as a major black leader in the controversy that arose over the program of Booker T. (25) Washington, the most prominent and influ- ential black leader at the opening of the twentieth century. Amidst the wave of lynchings, disfranchisement, and segregation laws, Washington, seeking the good will of (30) powerful whites, taught blacks not to protest against discrimination, but to elevate them- selves through industrial education, hard work, and property accumulation; then, they would ultimately obtain recognition of their (35) citizenship rights. At first Du Bois agreed with this gradualist strategy, but in 1903 with the publication of his most influential book, Souls of Black Folk, he became the chief leader of the onslaught against (40) Washington that polarized the black com- munity into two wings—the "conservative" supporters of Washington and his "radical" critics.

多选题Since Fisher's time, it has been realized that genes can sometimes influence the chromosome or gamete in which they find themselves so that the gamete will be more likely to participate in fertilization. If such a gene occurs on a sex-determining (X or Y) chromosome, then highly aberrant sex ratios can occur. But more immediately relevant to game theory are the sex ratios in certain parasitic wasp species that have a large excess of females. In these species, fertilized eggs develop into females and unfertilized eggs into males. A female stores sperm and can determine the sex of each egg she lays by fertilizing it or leaving it unfertilized. By Fisher's argument, it should still pay a female to produce equal numbers of sons and daughters. Hamilton, noting that the eggs develop within their host—the larva of another insect—and that the newly emerged adult wasps mate immediately and disperse, offered a remarkably cogent analysis. Since only one female usually lays eggs in a given larva, it would pay her to produce one male only, because this one male could fertilize all his sisters on emergence. {{U}}Like Fisher, Hamilton looked for an evolutionarily stable strategy, but he went a step further in recognizing that he was looking for a strategy.{{/U}} The author suggests that the work of Fisher and Hamilton was similar in that both scientists A. conducted their research at approximately the same time. B. sought to manipulate the sex ratios of some of the animals they studied. C. sought an explanation of why certain sex ratios exist and remain stable. D. studied game theory, thereby providing important groundwork for the later development of strategy theory. E. studied reproduction in the same animal species.

多选题In 2007, Mother Jones published an article on "the ethanol effect," showing the negative ramifications of switching from foreign oil to corn-based ethanol. It pointed out that over just five years, the amount of corn used for ethanol had risen from 7 percent to 20 percent. That led to a rise in the price of corn, which in turn led to a rise in food prices. Since so much corn was used to manufacture ethanol, less was exported. This meant less corn on the global market and the potential of an increase in global hunger. Ironically, the production of corn requires a great deal of gasoline for tractors and harvesters, reducing the energy savings to below that of gasoline.

多选题Influenced by the view of some twentieth-century feminists that women's position within the family is one of the central factors determining women's social position, some historians have {{U}}underestimated the significance of the woman suffrage movement.{{/U}} These historians contend that nineteenth-century suffragist was less radical and, hence, less important than, for example, the moral reform movement or domestic feminism—two nineteenth-century movements in which women struggled for more power and autonomy within the family. True, by emphasizing these struggles, such historians have broadened the conventional view of nineteenth-century feminism, but they do a historical disservice to suffragism. Nineteenth-century feminists and anti-feminist alike perceived the suffragists' demand for enfranchisement as the most radical element in women's protest, in part because suffragists were demanding power that was not based on the institution of the family, women's traditional sphere. When evaluating nineteenth-century feminism as a social force, contemporary historians should consider the perceptions of actual participants in the historical events. The author of the passage asserts that some twentieth-century feminists have influenced some historians view of the A. significance of the woman suffrage movement. B. importance to society of the family as an institution. C. degree to which feminism changed nineteenth-century society. D. philosophical traditions on which contemporary feminism is based. E. public response to domestic feminism in the nineteenth-century.

多选题A serious critic has to comprehend the particular content, unique structure, and special meaning of a work of art. And here she faces a dilemma. The critic must recognize the artistic element of uniqueness that requires subjective reaction; yet she must not be unduly prejudiced by such reactions. Her likes and dislikes are less important than what the work itself communicates, and {{U}}her preferences may blind her to certain qualities of the work{{/U}} and thereby prevent an adequate understanding of it. Hence, it is necessary that a critic develop a sensibility informed by familiarity with the history of art and aesthetic theory. On the other hand, {{U}}it is insufficient to treat the artwork solely historically,{{/U}} in relation to a fixed set of ideas or values. The critic's knowledge and training are, rather, a preparation of the cognitive and emotional abilities needed for an adequate personal response to an artwork's own particular qualifies. The author implies that it is insufficient to treat a work of art solely historically because A. doing so would lead the critic into a dilemma. B. doing so can blind the critic to some of the artwork's unique qualities. C. doing so can insulate the critic from personally held beliefs. D. subjective reactions can produce a biased response. E. critics are not sufficiently familiar with art history.
