D选项说了广告商说了平均每期ISSUE上出的广告费没变，但由于ISSUE的总数减少了，肯定杂志社要损失啊。E应该是无关选项吧

文章讨论的是邮费的成本带来的影响，生产成本是无关的

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.  

Premise:      plan to reduce 1/2 # of issues
Conclusion:   profit decline


A, 贵1/3每一个issue，但是减少了1/2的量，总体还是增加了
B无关  quality not change
C无关，subscribe prc not change
D advertises not lost， 但是ad amount/issue 也不变， ads revenue= (# issue)* (ads amoun/issue) 因为 # issue 减少到一半，所以ads revenue 减少了一半
E 成本不变

postage rates increase ==> plan to cut issue # ==> #issue decreases ==> ads revenue decreases

don't focus too much on the postage rates,
actually the premise of the argument is the plan to cut  issue amount, so that the amount of issue is what affects the profit the most

广告费又不是生产成本，怎么会和生产成本扯上关系。文章说的是为了降低邮费而采取的措施对公司利润的影响，广告费的降低就是这种影响啊
