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.（D）

(E) Production costs for the magazine are expected to remain stable.

怎么会是d呢，怎么也想不明白了

原文说issue减少了

D说：spend the same amount on advertising per issue

issue少了，ads就少了。 收入低了

但是The quality of articles下降了

我觉得每个issue的cost很可能也下降了

那么每个issue的advertisment 收入没有跟着降低的情况下

profit不一定下降呀
