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.

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

D是说那些early buyer都是兴趣来的快也去的快的人，因此根据他们的情况对其他人做判断是不准确的。所以就削弱了原文的结论。

//要求指出题目的逻辑错误。

原文讨论的是打广告对吸引烟民换牌子是不是有效，所有A无关。
没有讨论未来，所以B错。
题目说有10%的人换牌子，所以并不是每个人都忠心。C错
题目没有提过这条。D错。
E对，原文根据的是这个行业平均数据，结论却是所有公司都不值得打广告。显然，很可能打广告对有些公司是有用。
