og10_121 咋整不明白呢?

121. Manufacturers sometimes discount the price of a product to retailers for a promotion period when the product is advertised to consumers. Such promotion often results in a dramatic increase in amount of product sold by the manufacturers to retailers. Nevertheless, the manufacturers could often make more profit by not holding the promotions.

Which of the following, if true, most strongly supports the claim above about the manufacturers’ profit?

(A) The amount of discount generally offered by manufacturers to retailers is carefully calculated to represent the minimum needed to draw consumers’ attention to the product.

(B) For many consumer products the period of advertising discounted prices to consumers is about a week, not sufficiently long for consumers to become used to the sale price.

(C) For products that are not newly introduced, the purpose of such promotions is to keep the products in the minds of consumers and to attract consumers who are currently using competing products.

(D) During such a promotion retailers tend to accumulate in their warehouses inventory bought at discount; they then sell much of it later at their regular price.
            D

(E) If a manufacturer fails to offer such promotions but its competitor offers them, that competitor will tend to attract consumers away from the manufacturer’s product.
            

答案是 D, 我怎么感觉应该是B?   题目说制造商的利润在不促销的时候,就可以more profit ,而答案是指的分销商会赚钱,好象不搭界.

促销期间价格降低，零售商买进大量商品，很大一部分只是因为便宜囤积货品罢了，促销期过了之后就按正常价零售，然后就有一段时间不用进货了。实际上是导致了制造商以促销价在非促销期卖出了商品，导致利润下降。

我一开始选的是B, 没想到答案是D, 因为答案D说的是零售商的利润如何赚取，并没有说制造商怎样。B的意思是说，可以促销一周，然后就恢复原价。好象也对。
