Most of this demand is generated by former East Germans who cannot yet afford new cars and for whom cars were generally unavailable prior to unification. This demand has outstripped supply and thus has exerted an upward pressure on the prices of used cars. Consequently, an increasing number of former West Germans, in order to take advantage of the improved market, will be selling the cars they have owned for several years. Hence, the German new-car market will most likely improve soon as well. Which one of the following, if true, would most help to support the conclusion about the German new-car market? (A) The demand for old cars in former West Germany is greater than the demand for new cars in former East Germany. (B) In most European countries, the sale of a used car is subject to less tax than is the sale of a new car. (C) Most Germans own very few cars in the course of their lives. (D) Most former West Germans purchase new cars once they sell their used cars. (E) Many former East Germans prefer to buy cars imported from North America because they are generally larger than European cars.
2. In 1980 health officials began to publicize the adverse effects of prolonged exposure to the sun, and since then the number of people who sunbathe for extended periods of time has decreased considerably each year. Nevertheless, in 1982 there was a dramatic rise in newly reported cases of melanoma, a form of skin cancer found mostly in people who have had prolonged exposure to the sun. Which one of the following, if true, helps to resolve the apparent discrepancy in the information above?
(A) Before 1980 a considerable number of the people who developed melanoma as a result of prolonged exposure to the sun were over forty years of age. (B) Before 1980, when most people had not yet begun to avoid prolonged exposure to the sun, sunbathing was widely thought to be healthful. (C) In 1982 scientists reported that the body’s need for exposure to sunlight in order to produce vitamin D, which helps prevent the growth of skin cancers, is less than was previously though. (D) In 1982 medical researchers perfected a diagnostic technique that allowed them to detect the presence of melanoma much earlier than had previously been possible. (E) Since 1980, those people who have continued to sunbathe for extended periods of time have used sunblocks that effectively screen out the ultraviolet rays that help cause melanoma. 3. The tiny country of Minlandia does not produce its own television programming. Instead, the citizens of Minlandia, who generally are fluent not only in their native Minlandian, but also in Boltese, watch Boltese-language television programs from neighboring Bolta. Surveys show that the Minlandians spend on average more hours per week reading for pleasure and fewer hours per week watching television than people anywhere else in the world. A prominent psychologist accounts for the survey results by explaining that people generally prefer to be entertained in their native language even if they are perfectly fluent in other languages. The explanation offered by the psychologist accounts for the Minlandian’s behavior only if which one of the following is assumed? (A) Some Minlandians derive no pleasure from watching television in a language other than their native Minlandian. (B) The study of Boltese is required of Minlandian children as part of their schooling. (C) The proportion of bilingual residents to total population is greater in Minlandia than anywhere else in the world. (D) At least some of what the Minlandians read for pleasure is in the Minlandian language. (E) When Minlandians watch Boltese television programs, they tend to ignore the fact that they are hearing a foreign language spoken. 4. Morris High School has introduced a policy designed to improve the working conditions of its new teachers. As a result of this policy, only one-quarter of all part-time teachers now quit during their first year. However, a third of all full-time teachers now quit during their first year. Thus, more full-time than part-time teachers at Morris now quit during their first year. The argument’s reasoning is questionable because the argument fails to rule out the possibility that (A) before the new policy was instituted, more part-time than full-time teachers at Morris High School used to quit during their first year (B) before the new policy was instituted, the same number of full-time teachers as part-time teachers at Morris High School used to quit during their first year (C) Morris High School employs more new full-time teachers than new part-time teachers (D) Morris High School employs more new part-time teachers than new full-time teachers (E) Morris High School employs the same number of new part-time as new full-time teachers 5.“Commercial real estate prices have been rising steadily in the Sandida Heights neighborhood for several years, while the prices in the adjacent neighborhood of Palm Grove have remained the same. It seems obvious, then, that a retail space in Sandida Heights must now be much more expensive than a similar space in Palm Grove, which was not the case several years ago. So, it appears that retail spaces in Sandida Heights are now overpriced relative to those in Palm Grove. Therefore, it would be in our financial interest to purchase a retail space in Palm Grove rather than in Sandida Heights.”作者: balapupu 时间: 2011-9-18 23:26
