136. Because postage rates are rising, Home Decorator magazine plans to maximize its profits by reducing by one half the number of issues it publishes each year.The quality of articles, the number of articles published per year, and the subscription price will not change. Market research shows that neither subscribers nor advertisers will be lost if the magazine's plan is instituted. Which of the following, if true, provides the strongest evidence that the magazine's profits are likely to decline if the plan is instituted? (A) With the new postage rates, a typical issue under the proposed plan would cost about one-third more to mail than a typical current issue would. (B) The majority of the magazine's subscribers are less concerned about a possible reduction in the quantity of the magazine's articles than about a possible loss of the current high quality of its articles. (C) Many of the magazine's long-time subscribers would continue their subscriptions even if the subscription price were increased. (D) Most of the advertisers that purchase advertising space in the magazine will continue to spend the same amount on advertising per issue as they have in the past. (E) Production costs for the magazine are expected to remain stable.
推理：每年出版期数减少一半，但每年的文章质量和数量没变，每期的定购价没变。所以杂志社的利润减少（这个利润应该是指每年的利润） D说广告商每期购买的广告费没变。所以每年广告费减少一半（因为期数减少一半）。当然杂志社利润就减少了。故为答案 A说虽然每期邮费增加，但期数减少。相抵消，虽然不知抵消情况，但原文没有信息让我们相信杂志社就亏了。故支持不了结论。 是花在每本期刊上的广告费：如果是每本书的话，D正确了。因为书少，广告费就少。 还是花在每一期上的广告费：如个是每一期的话，D似乎反而加强了。因为如果广告费按期给的话，则和发行量就没关系了。比如甲给乙1000块一期，乙本来是发1000本，现在乙发500本，但是还是每一期从甲这里拿1000块，反而利益最大化了。 这样的话，对于per issue的理解就比较重要了 是否能给一个定义呢？是“一本杂志”还是“一期杂志”？ |
