1.1.17 stock-keeping units@--- 解释现象
近年来的一个矛盾现象---虽然scanner和其他先进的技术可以使company生产少量的多样化的产品，但还是有越来越多的inventory不足或过剩的现象。
原文！公司必须做好预测来防止产能不足或者过量生产，科技进步，比如scanner和小批量生产技术，让新产品发布越来越频繁，导致两个后果：1.产品生命周期短，需要花大钱投资发明新产品保持领先 2.新产品激增-》库存多，导致需求量减少。虽然厂商可以预测这个需求，但是要预测具体的某一产品的需求则会很难。
Companies that must determine well in advance of the selling season how many units of a new product to manufacture often underproduce products that sell well and have overstocks of others. The increased incidence in recent years of mismatches between production and demand seems ironic, since point-of-sale scanners have improved data on consumers’ buying patterns and since flexible manufacturing has enabled companies to 24 produce, cost-effectively, small quantities of goods. This type of manufacturing has greatly increased the number of new products introduced annually in the United States. However, frequent introductions of new products have two problematic side effects. For one, they reduce the average lifetime of products; more of them are neither at the beginning of their life (when prediction is difficult) or at the end of their life (when keeping inventory is expensive because the products will soon become obsolete). For another, as new products proliferate, demand is divided among a growing number of stock-keeping units (SKU’s). Even though manufacturers and retailers can forecast aggregate demand with some certainty, forecasting accurately how that demand will be distributed among the many SKU’s they sell is difficult.  For example, a company may be able to estimate accurately the aggregate number of shoes it will sell, but it may be uncertain about which specific types of shoes will sell more than other types.
问题是
Q35:
Which of the following most accurately describes the function of the last sentence in the passage (lines 35-40)?
A.    To cite a situation in which the aggregate demand is more important than the distribution of demand among SKU’s
B.    To refute an assertion about the side effects of flexible manufacturing
C.    To illustrate an assertion about companies’ ability to forecast demand
D.    To provide an example of ways in which companies address the difficulties of forecasting demand
E.    To note an exception to the author’s assertion about distributing demand among SKU’s

看到一些同学整理的里面选的C,原始的里面选的D
这题到底选哪个啊?

有没有人来确定下啊...明天早上就上战场了,急啊!

应该是C

是D.  C是说很难确定需求。其实文章是说他们已经能够预测需求会增多，只是在需求增多的里面哪些是这种产品增加，哪些是那种产品增加他们没法确定，所以是D.

顺便说一下，俺今天早上刚考完，第一篇就是这个文章。运气超好的是我考前2天做了这篇，错了几个，好好研究了一把。哈哈。祝你好运！
