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.

多选题Tocqueville, apparently, was wrong. Jacksonian America was not a fluid, egalitarian society where individual wealth and poverty were ephemeral conditions. At least so argues E. Pessen in his iconoclastic study of the very rich in the United States between 1825 and 1850. Pessen does present a quantity of examples, together with some {{U}}refreshingly intelligible statistics,{{/U}} to establish the existence of an inordinately wealthy class. Though active in commerce or the professions, most of the wealthy were not self-made, but had inherited family fortunes. In no sense mercurial, these great fortunes survived the financial panics that destroyed lesser ones. Indeed, in several cities the wealthiest one percent constantly increased its share until by 1850 it owned half of the community's wealth. Although these observations are true, Pessen overestimates their importance by concluding from them that the undoubted progress toward inequality in the late eighteenth century continued in the Jacksonian period and that the United States was a class-ridden, plutocratic society even before industrialization. The author's attitude toward Pessen's presentation of statistics can be best described as A. disapproving B. shocked C. suspicious D. amused E. laudatory

多选题The {{U}}common{{/U}} belief of some linguists that {{U}}each language is a perfect vehicle{{/U}} for the thoughts of the nation speaking it is in some ways the exact counterpart of the conviction of the Manchester school of economics that supply and demand will regulate everything for the best. Just as economists were blind to the numerous cases in which the law of supply and demand left actual wants unsatisfied, so also many linguists are deaf to those instances in which the very nature of a language calls forth misunderstandings in everyday conversation, and in which, consequently, a word has to be modified or defined in order to present the idea intended by the speaker: "He took his stick—no, not John's, but his own." {{U}}No language is perfect{{/U}}, and if we admit this truth, we must also admit that it is not unreasonable to investigate the relative merits of different languages or of different details in languages. The primary purpose of the passage is to A. analyze an interesting feature of the English language. B. refute a belief held by some linguists. C. show that economic theory is relevant to linguistic study. D. illustrate the confusion that can result from the improper use of language. E. suggest a way in which languages can be made more nearly perfect.
