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.
Answer
我选了E 因为题目里面说the subscription price will not change.
Market research shows that neither subscribers nor advertisers will be lost if the magazine's plan is instituted.
同时发行的issue减少，那么发行量*每本价格=收入（issue减少，这个收入减少）
题目问profits are likely to decline ，在收入减少的情况下，利润也减少，就要保证成本没有也减少，如E所说，成本不变，收入减少，那么利润就减少了。
至于D，仍然在讨论广告费使得该杂志收入减少的问题，和利润不沾边吖。。。
不知道是哪里想错了，希望NN指点。先谢谢啦！

非NN啊·~~
利润=收入-成本，
D中的advertisers的花费是报纸的收入的一部分，随着issues的减少，收入减少，所以利润下降。
E中的production cost是成本的一部分，成本不变，其利润不变的啊~~~

但是issues减少，而且price不变，收入已经减少了
就需要考虑一下cost了
D中还是在说收入，如果cost因为技术原因下降很多，profit还是有可能提高的吖

postage rates are rising（单本发行成本上升）So plans to maximize its profits by reducing by one half the number of issues it publishes each year（减少发行数量，以减少发行成本）。
The quality of articles,（质量不变=Production costs不变） the number of articles published per year（稿费照样要付）, and the subscription price will not change.，（价格不变）
--------------------------------------------------
profits=总收入-总成本
Total Cost =产品成本++发行成本
产品成本=稿费（文章照样那么多，付给作者稿费照样那么多）+纸张成本（发表文章数量不变，杂志更厚）
发行成本= postage rates ( rising )/per issues * the number of issues ( reducing )
总收入= （ advertisers/per issue+the subscription price/per iusse）*the number of issues
所以选择D，就是指出来公司企图减少 the number of issue 来减少发行成本，但是没有顾忌到 advertisers 的profit 也会减少
所以文章说
Market research shows that neither subscribers nor advertisers will be lost if the magazine's plan is instituted.
E答案实际是和原文违背
当然如果实战这么分析，那完了，只能说凭借感觉， D是无关选项，文章强调重点在
subscribers 和 advertisers （ 隐含关键因素the number of issues），成本这里基本上是被忽略的。

我是这么想的，一开始选的A，没有考虑到发行成本减不到一半这个事实。收入＝发行期数＊（每本单价＋广告）＝从读者来的钱＋从广告商来的钱
成本＝编制成本＋发行成本
利润＝收入－成本
广告商和订阅人的数目不变，总文章数不变，每本单价不变，发行期数减半
à
从读者来的钱减半，从广告商来的钱不一定（要看广告单价和发行期数），编制成本不变，发行成本不一定（要看重量和运输单价的乘积）
à
关键是比较 从广告商来的钱－发行成本 注意发行成本不可能减半，因为每期变厚
Ａ总发行成本为原来的２／３＝（４／３）＊（１／２），如果从广告商来的钱不变（广告加价，发行数减少），总差价还会增加
Ｂ无关
Ｃ重复题目信息，无关
Ｄ从广告商来的钱减半，发行成本减不到一半，所以肯定输钱
Ｅ编制成本不变，重复题目信息，无关

收入-成本
如果利润少了，可能是收入少或者是成本大了，所以找能起到这两种作用的选择项。
(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.邮运成本增加了三分之一，但是数量已经被减半了，所以邮运成本变成：原成本*50%*（1+1/3）是原来成本的66%还是减少了成本所以
(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.读者不关心数量减少更关心质量会不会有变。无关
(C) Many of the magazine's long-time subscribers would continue their subscriptions even if the subscription price were increased.老读者即使在单价涨的情况下也会接着买，只会增加利润
(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. Issue数少了，那从广告商来的钱就少了，因为广告商的每本投入量是一样的。利润减少
(E) Production costs for the magazine are expected to remain stable.成本不变。对利润没影响
