标题: prep里的一道逻辑~貌似不是很绕~我就是绕不对!唉~~
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.

是prep的原题,答案也不记得了~~

有没有做过的tx~~~帮帮忙啊!

【新信息,文中直说postage涨,涨多少没有说。但是从某重程度上来说,是支持原文结论,削弱“the magazine's profits are likely to decline ”。因为由于邮资高了,成本高了,所以在保证杂志年费不变的情况下,减少期刊发行的频率就是降低cost】
  (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.
【与原文矛盾,文章说 The quality of articles, the number of articles published per year, and the subscription price will not change.  
  (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.
【Correct,这个说明广告商每期赞助的钱是一样的,那么期刊的issue数减半,那么广告收入必定减半。

答案好像没有贴全啊,漏掉E了。不过应该是选D。

非常感谢~~明白多了

不是很同意
profit=revenue-cost
revenue增长不是profit增长的充分条件

与1楼的分析略有不同,我认为
(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.plan
弥补了邮费费率的影响,而且应该是比原来的成本更低了
假设:原来每期邮费1,期数2;现在每期邮费4/3,期数1
成本降低因为4/3*1<1*2,所以A是支持利润上升而非下降

不同意#4.
本题A选项并不严密。从选项看成本降低,但是减少一半产量,利润也降低。只有原成本*数量小于新成本*数量/2,才能证明利润降低。
但是从A选项中只能看见单个成本,不能证明利润是否上升或下降。

不是很严密的一题,A也好E也好 如果不严密的假设是实际销量可能上升,可能下降,造成无法预知实际利润走向

但是对于D来说也一样,如果销量上升 公司的利润一样未必下降

这题的题干逻辑我就很不懂
按照一般理解邮费不是成本的一部分么, 成本高了如果其他的价钱都控制不变不是应该数量上卖更多增加revenue从而增加profit么?
现在说减少发行数量去增加profit, 似乎是卖得多就亏得多
而且发行量默认等于销量了么???



不明白啊..快来人来反驳我啊!!

想多了都  选D   看清楚D 是per issue  有一个per  
作者: abc791201064    时间: 2013-8-31 10:40
这里其实还是有点乱 我认为就是  利润=收入-支出  支出这里是不变的实际上  就看收入=数量乘价格  价格D说一样 数量不能因为issue少了有上升的可能 所以D

我想问的是,这里题目的issues是啥意思呀?
说了质量、发行文章数量、价格都不变,那issues是啥减了半??

issue说的是期数。比如说月刊,一年12期。现在杂志社计划将一年12期改成一年6期。

对,这样就对revenue造成了影响

即使题干花了很大力气说成本不变,R一旦变了,P也会变

the number of issues是每年的发行次数, 比如每个月一次的期刊变成每个月两次的期刊;

subscription price此处应该指每年的订阅费用, 这样其实相当于每期的费用价格翻倍, 就算邮费有上升还是有利润的

这样理解就能解释为什么要文章要说文章的质量不变, 每年的文章数量不变了。

另外这道题还有个解法, 题目地一句就说邮费上涨, A选项只是进一步解释上涨的幅度。 没有逻辑链路上的更多的信息,其实属于无关信息。
