Q23 to Q25:

Companies that must determine well in advance of the selling season how many unites of a new product to manu-

Line facture often underproduce products

(5) 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

(10) improved data on consumers’buying patterns and since flexible manufac- turing has enabled companies to

produce, cost-effectively, small quantities of goods. This type of

(15) 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

(20) 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 expen-

(25) sive 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

(30) 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.

(35) 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.

----------------------------------------------------------------------------- Q23:

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

------------------------------------------------------------------------------ answer is C I choose D

I chose D too, because I referred the "forecasting accurately how
that demand will be distributed among
the many SKU’s they sell is difficult.", the sentence before this example, and because the example often follow an idea or suggestion  to explain it. So, I chosed D, but I think that C is reseanal too, so, it is open discuss. thanks for any further discussion.

这道题是该选C,我开始也错选D了。文章里没有提到一种WAY,公司使用它来 address the difficulties of forecasting demand 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.

从这里可以找到C说的ability
