1. To avoid a hostile takeover attempt, the board of directors of Wellco, Inc., a provider of life and health insurance, planned to take out large loans and use them to purchase a publishing company, a chocolate factory, and a nationwide chain of movie theaters. The directors anticipated that these purchase initially would plunge the corporation deep into debt, rendering it unattractive to those who wanted to take it over, but that steadily rising insurance rates would allow the company to pay off the debt within five years. Meanwhile, revenues from the three new businesses would enable the corporation as a whole to continue to meet its increased operating expenses. Ultimately, according o the directors’ plan, the diversification would strengthen the corporation by varying the sources and schedules of its annual revenues. Which of the following, assuming that all are equally possible, would most enhance the chances of the plan’s success? (A) A widespread drought decreases the availability of cacao beans, from which chocolate is manufacture, diving up chocolate prices worldwide. (B) New government regulations require a 30 percent across-the-board rate rollback of all insurance companies, to begin immediately and to be completed within a five-year period. (C) Congress enacts a statute, effective after six months, making it illegal for any parent not to carry health insurance coverage for his or her child. (D) Large-screen televisions drop dramatically in price due to surprise alterations in trade barriers with Japan; movie theater attendance dwindles as a consequence. (E) A new, inexpensive process is discovered for making paper pulp, and paper prices fall to 60 percent of their former level. 这个题答案是选的c，可是我怎么都看不明白 2.Critics of sales seminars run by outside consultants point out that since 1987, revenues of vacuum cleaner companies whose employees attended consultant-led seminars were lower than revenues of vacuum cleaner companies whose employees did not attend such seminars. The critics charge that for vacuum cleaner companies, the sales seminars are ill conceived and a waste of money. Which of the following, if true, is the most effective challenge to the critics of sales seminars? (A) Those vacuum cleaner companies whose sales were highest prior to 1987 are the only companies that did not send employees to the seminars. (B) Vacuum cleaner companies that have sent employees to sales seminars since1987 experienced a greater drop in sales than they had prior to 1987. (C) The cost of vacuum cleaner sales seminars run by outside consultants has risen dramatically since 1987. (D) The poor design of vacuum cleaner sales seminars is not the only reason for their ineffectiveness (E) Since 1987, sales of vacuum cleaners have risen twenty percent. 这个题答案选的是A，总觉得A选项是无关的 3， A recent survey of all auto accident victims in Dole
County found that, of the severely injured drivers and front-seat passengers, 80 percent were not wearing seat belts at the time of their accidents. This indicates that, by wearing seat belts, drivers and front-seat passengers can greatly reduce their risk of being severely injured if they are in an auto accident. The conclusion above is not properly drawn unless which of the following is true? (A) Of all the drivers and front-seat passengers in the survey, more than 20 percent were wearing seat belts at the time of their accidents. (B) Considerably more than 20 percent of drivers and front-seat passengers in Dole
County always wear seat belts when traveling by car. (C) More drivers and front-seat passengers in the survey than rear-seat passengers were very severely injured. (D) More than half of the drivers and front-seat passengers in the survey were not wearing seat belts at the time of their accidents (E) Most of the auto accidents reported to police in Dole
County do not involve any serious injury. 这个题答案是A，不懂！ 4. Six months or so after getting a video recorder, many early buyers apparently lost interest in obtaining videos to watch on it. The trade of businesses selling and renting videos is still buoyant, because the number of homes with video recorders is still growing. But clearly, once the market for video recorders is saturated, businesses distributing videos face hard times. Which of the following, if true, would most seriously weaken the conclusion above? (A) The market for video recorders would not be considered saturated until there was one in 80 percent of homes. (B) Among the items handled by video distributors are many films specifically produced as video features. (C) Few of the early buyers of video recorders raised any complaints about performance aspects of the new product. (D) The early buyers of a novel product are always people who are quick to acquire novelties, but also often as quick to tire of them (E) In a shrinking market, competition always intensifies and marginal businesses fail. 这个题答案选D,我怎么看都觉得early buyers和题目都是无关的 5. Surveys show that every year only 10 percent of cigarette smokers switch brands. Yet the manufacturers have been spending an amount equal to 10 percent of their gross receipts on cigarette promotion in magazines. It follows from these figures that inducing cigarette smokers to switch brands did not pay, and that cigarette companies would have been no worse off economically if they had dropped their advertising. Of the following, the best criticism of the conclusion that inducing cigarette smokers to switch brands did not pay is that the conclusion is based on (A) computing advertising costs as a percentage of gross receipts, not of overall costs (B) past patterns of smoking and may not carry over to the future (C) the assumption that each smoker is loyal to a single brand of cigarettes at any one time (D) the assumption that each manufacturer produces only one brand of cigarettes (E) figures for the cigarette industry as a whole and may not hold for a particular company 答案选E 希望各位能帮忙解答一下，谢谢！ Critics of sales seminars run by outside consultants point out that since 1987, revenues of vacuum cleaner companies whose employees attended consultant-led seminars were lower than revenues of vacuum cleaner companies whose employees did not attend such seminars.
