[求助]OG-136还没解决的疑惑

问题比较长啊,希望牛牛多给我点耐心,谢谢

136. 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.

答案是D,没什么疑问,但我对BC的排除思路和ETS不一样,也不能理解他的意思:
OG关于BC的解释是: choice B and C are incorrect, because neither describes concerns that subscribers have about the plan under consideration.

1.但我觉得是B选项中的quality和quantity在原文中都相同,所以subscribers再怎么比较不关心那个,都无所谓,所以排除;      

2.而C我觉得它是consistent with原文,所以不起削弱作用,所以排除.因为原文中说Market research shows that neither subscribers nor advertisers will be lost if the magazine's plan is instituted.

OG上的解釋是說, BC兩個選項都沒有提到訂閱人真正”攸關（concerns）”的事

就我理解來看，OG的注釋和你的理解是一樣的
