Manufactures sometimes discount the price of a product to retailers for a promotion period when the product is advertised to consumers。Such promotions often result 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 ture，most strongly supports the claim above about the manufacturer’s profit？

A。The amount of discount generally offered by manufacturers to retailers is carefully calculated to represent the minimum needed to draw consumer's attention to the product
B。For many consumer products the period of advertiseing discounted prices to consumers is about a week，not sufficiently long for consumersto become used to the sale price
C。For products that are not newly introduced，the purpose of such promotion is to keep the products in the minds of consumers and to attract consumers who are using competing products
D.During such a promotion retailers tend to accumulate in their warehouse inventory bought at discount；they then sell much of it later at their regular price
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


答案说D算是最正确的答案，我完全看不出，求NN们解答

LS is right.

Claim: the manufactures could often make more profit by not holding the promotions.

During such a promotion RETAILERs (not manufacture) tend to accumulate in their warehouses inventory bought at discount, they then sell much of its inventory later at their regular price.  If so, a retailer can accumulate all the products it wants during the promotion and need not buy any product at regular prize from the manufacture.  Thus, the profit for the manufacture is lower than the profit could have been without the promotion.

This answer choice supports the conclusion of the argument.

The focus is not during the promotion, but after the promotion. Because the retailer accumulated more products than it could sell during the promotion, then after the promotion it would order FEWER products from the manufacture for future demands from the customers.  Without the promotion, the retailer HAS to order these regular-priced products from the manufacture for customers.

原文配合d项的大意是生成商通过给销售商提供打折来多卖产品，而销售商却把这些打折买来的商品存着，然后以正常的价格卖出去。注意销售商还是以正常的价格卖出去，所以这类商品的出售总额对于生产商来说没变（给予足够时间），（也就是只是短时间的增加，最后的销售量不变）而生产商却又把自己卖给销售商的价格降低了，导致利润减少，所以生产商不应降价
