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 shouws 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 hgh 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.

答案选D，我实在想不通，既然做广告的人不会因为issue的数量而减少费用，杂志也没说减少给广告留的地方，为什么这个会说明了计划会导致利润下降呢？

明天就考了，急！请NN指点！

先是"reducing by one half the number of issues"

然后D是,每一期花一样的钱,但是总的the number of issues少了,所以广告费少了

相信楼主已经没时间看了哈,还是希望考试顺利
