电话的销售量去年升高，M计划增加电话产量，并且继续大量投入广告。

问那个选项说明M不能通过上述策略盈利。（削弱）

A.share of all telephones sales .市场占有率，无关，只要sales升高就可盈利。

B.average inventory of telephones  存货，无关

C.brand name of Mammoth's telephones知名度以及顾客是否知道M拥有这个品牌 与能否盈利无直接关系

D. M是去年sales上升的牌子之一，该策略可行，支持。

E在说：尽管价格微幅下调，去年的销量还是下降了。这就说明在整体市场“Sales of telephones have increased dramatically over the last year. ”的情况下，MI的销量都下降了，即使今年整体市场形势还是很好，但MI的市场销量未必好，那么扩大生产也未必必要。
