向NN们请教一道XDF书上的CR，关于三种诉诸的

ucicc

Paper & Print is a chain of British stores selling magazines, books, and sationery products. In Britain, magazines' retail prices are set by publishers, and the retailer's share of a magazine's retail price is 25 percent. Since Paper & Print margin on books and stationary products is much higher, the chain's management plans to devote more of its stores' shelf space to books and stationary products and reduce the number of magazines titles that its stores carry.

Which of the following, if true, most strongly argues that the plan, if put into effect, will not increase Paper & Print's profits?

(A) Recently magazine publishers, seeking to increase share in competitive sectors of the market, have been competitively cutting the retail prices of some of the largest circulation magazines.
(B) In market research surveys, few consumers identify Paper & Print as a book or stationary store but many recognize and value the broad range of magazines it carries.
(C) The publisher's share of a magazine's retail price is 50 percent, and the publisher also retains all of the magazine's advertising revenue.
(D) Consumers who subscribe to magazine generally pay less per issue than they would if they bought the magazine through a retail outlet such as Paper & Print.
(E) Some of Paper & Print location are in small towns and represent the only retail outlet for books within the community.

答案是B，记得XDF说过有诉诸的三种错误：诉诸权威、诉诸公众意见和诉诸情感，那B应该是诉诸公众意见呀，为什么还选B呢？

题目类型：问削弱

逻辑过程：
我的想法是：

前提：书和文具的利润比杂志高。
结论：调整更多的货架给书和文具（增加销售额），利润上升。

削弱方法：割断因果（有果无因），即：因（调整更多的货架给书和文具，增加销售额）本身不成立。

B选项说：客户认为Paper & Print就是个买杂志的店，即：调整更多的货架给书和文具并不能增加书和文具销售额，（客户可能不会来这店买），利润也不会增加。

谢谢waterlooer，要是排除法也只能选B，但是我当时看到“ In market research surveys”就觉得这种削弱不靠谱...

我也觉得有的选项貌似无关，其实有关。
