请教紫皮OG81

81. An eyeglass manufacturer tried to boost sales for the summer quarter by offering its distributors a special discount if their orders for that quarter exceeded those for last year's summer quarter by at least 20 percent．Many distributors qualified for this discount．Even with much merchandise discounted，sales increased enough to produce a healthy gain in net profits．The manufacturer plans to repeat this success by offering the same sort of discount for the fall quarter．

Which of the following，if true，most clearly points to a flaw in the manufacturer's plan to repeat the successful performance of the summer quarter?

(A)  In general, a distributor's orders for the summer quarter are no higher than those for the spring quarter．

(B)  Along with offering special discounts to qualifying distributors，the manufacturer increased newspaper and radio advertising in those distributors’ sales areas．

(C)  The distributors most likely to qualify for the manufacturer's special discount are those whose orders were unusually low a year earlier.

(D)  The distributors who qualified for the manufacturer's special discount were free to decide how much of that discount to pass on to their own customers．

(E)  The distributors’ ordering more goods in the summer quarter left them overstocked for the fall quarter．
这道题目的答案是E，可是我不明白，E和题干有什么关系，不知道谁能帮忙解释一下，谢谢啊。

题干的中文意思是如果经销商的订货数量超过去年夏季的20%，工厂就会给他们一个折扣，很多经销商都做到了，所以厂家认为这个策略很成功，于是厂家决定在即将到来的秋季再次实施此计划。那么厂家的预期就是秋季也会像夏季一样成功。

答案E指出经销商订货超过去年20% 不是他真的卖了这么多，而是存起来了，所以秋季他需要把存货先卖出去以后才能考虑再向工厂下订单。这样的话，这个计划怎么能再次起效呢？

distributors在夏季为了享受discount拼命要货，造成库存堆积，因此你秋季再搞这种discount活动，自然没效果喽！
