111. Sales of telephones have increased dramatically over
the last year. In order to take advantage of this increase,
Mammoth Industries plans to expand production of its own model of telephone, while continuing its already very extensive advertising of this product.
Which of the following, if true, provides most support for the view that Mammoth Industries cannot increase its sales of telephones by adopting the plan outlined above?
(A) Although it sells all the telephones that it produces, Mammoth Industries' share of all telephone sales has declined over the last year.
(B) Mammoth Industries' average inventory of telephones awaiting shipment to retailers has declined slightly over the last year.
(C) Advertising has made the brand name of Mammoth Industries' telephones widely known, but few consumers know that Mammoth Industries owns this brand.
(D) Mammoth Industries' telephone is one of three brands of telephone that have together accounted for the bulk of the last year's increase in sales.
E Despite a slight decline in the retail price, sales of Mammoth Industries' telephones have fallen in the last year.
答案C 为什么不对呢, M 只是三个厂家中的一个,而去年的电话销售额增长是三个共同的统计,也有可能M 是下降的, 但是三个厂家共同的还是增长的, ?????????
C:提到了顾客,这和顾客没什么关系
D:只是说是统计的三家之中的一家,这并不能证明,M厂就是增长或者是下降的
打个比方,A=6 B=100 M=-5,平均值是高的,但是M是低的
同理,A=-5 B=100 M=6,平均值还是一样,但是M是正的了
所以平均值本身并不能说明问题
E:说M厂去年的销量低,去年大盘增长的情况下,销量还是下降的,这怎么可能再上升呢。其实是对cannot increase 的一个改写,用了fallen来改写
偶明白了,D答案只是不能够充分确定是增长还是减少,所以对cannot increase 不能起任何作用

Sorry for being an economic subject newbie:
does decline in price always mean increase in sale?
