[求助]prep中的一CR题

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 the 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?

...
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.

正确答案是D

我怎么看着觉得 D选项 应该是证明利润不会下降呀？

请各位帮我看看哦。。。

文章中说,杂志社计划削减出版的数量来提高利润....为了提高利润说了很多费话...

D说的是,多数的广告商在每期杂志的广告数量是相同的.

说明了,杂志期数减少,每期的广告数不变.那么,能赚到的广告的钱必然减少了.....
