大全-10-1.        In 1985 in the country of Alissia, farmers brought to market a broccoli crop that was one-and-a-half times as large as the 1985 broccoli crop in its neighbor country, Barbera. Yet total quantities of broccoli available for sale to consumers in Alissia were smaller than were total quantities in Barbera in 1985.
Which of the following, if true, in 1985, contributes most to an explanation of why there was less broccoli available for sale to consumers in Alissia than in Barbera?
(A) Barbera’s farmers produced much more cabbage than did Alissia’s farmers.
(B) Barbera’s farmers produced fewer heads of broccoli per acre than did Alissia’s farmers.
(C) Alissia exported a much higher proportion of its broccoli crop than did Barbera.
(D) Broccoli was much more popular among consumers in Alissia than in Barbera.
(E) Alissia had more land suitable for growing broccoli than did Barbera.

大全-10-4.        The fossil record shows that the climate of North America warmed and dried at the end of the Pleistocene period. Most of the species of large mammals then living on the continent became extinct, but the smaller mammalian species survived.
Which of the following, if true, provides the best basis for an explanation of the contrast described above between species of large mammals and species of small mammals?
(A) Individual large mammals can, in general, travel further than small mammals and so are more able to migrate in search of a hospitable environment.
(B) The same pattern of comparative success in smaller, as opposed to larger, species that is observed in mammals is also found in bird species of the same period.
(C) The fossil record from the end of Pleistocene period is as clear for small mammals as it is for large mammals.
(D) Larger mammals have greater food and space requirements than smaller mammals and are thus less able to withstand environmental change.
(E) Many more of the species of larger mammals than of the species of smaller mammals living in North America in that period had originated in climates that were warmer than was that of North America before the end of the Pleistocene period.

大全-10-8.        For the safety-conscious Swedish market, a United States manufacturer of desktop computers developed a special display screen that produces a much weaker electromagnetic field surrounding the user than do ordinary screens. Despite an advantage in this respect over its competitors, the manufacturer is introducing the screen into the United States market without advertising it as a safety improvement.
Which of the following, if true, provides a rationale for the manufacturer’s approach to advertising the screen in the United States?
(A) Many more desktop computers are sold each year in the United States market than are sold in the Swedish market.
(B) The manufacturer does not want its competitors to become aware of the means by which the company has achieved this advance in technology.
(C) Most business and scientific purchasers of desktop computers expect to replace such equipment eventually as better technology becomes available on the market.
(D) An emphasis on the comparative safety of the new screen would call into question the safety of the many screens the manufacturer has already sold in the United States.
(E) Concern has been expressed in the United States over the health effects of the large electromagnetic fields surrounding electric power lines.

大全-10-16.        In the 1970’s there was an oversupply of college graduates. The oversupply caused the average annual income of college graduates to fall to a level only 18 percent greater than that of workers with only high school diplomas. By the late 1980’s the average annual income of college graduates was 43 percent higher than that of workers with only high school diplomas, even though between the 1970’s and the late 1980’s the supply of college graduates did not decrease.
Which of the following, if true, in the late 1980’s, best reconciles the apparent discrepancy described above?
(A) The economy slowed, thus creating a decreased demand for college graduates.
(B) The quality of high school education improved.
(C) Compared to the 1970’s, a greater number of high schools offered vocational guidance programs for their students.
(D) The proportion of the population with at least a college-level education increased.
(E) There was for the first time in 20 years an oversupply of job seekers with only high school diplomas.
