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.

Which of the following most accurately describes the function of the last sentence in the passage (Last 2 lines)?
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

OA:C

The passage suggests which of the following about divided demand among a growing number of SKU's?
A. It has increased the average lifetime of products.
B. It has resulted from retailer's attempts to predict demand more accurately and
avoid both understocks and overstocks.
C. It has decreased the use of flexible manufacturing by companies.
D. It has not increased the expense of keeping inventory of certain products.
E. It has not prevented companies from predicting aggregate demand with some certainty.

OA:E Why not B

According to the passage, which of the following has led to growth in the number of new products introduced in the United States each year?
A. Reduced average lifetime of products
B. Increased ability to forecast aggregate demand
C. More cost-effective ways of keeping inventory for products
D. Cost-effective production of small quantities of goods
E. Increased ability to divide demand among a number of SKU's and to forecast how that demand will be distributed among those SKU'

OA:[spoiler]D Why not A [/spoiler]

The second-to-last sentence tells us that while manufacturers and retailers can accurately forecast aggregate demand, they're not great at forecasting the specific composition of that demand. Then we get an example of this. So we're getting an assertion about companies' ability to forecast demand (better at the general than the specific) and then we're getting an illustration of this assertion (total shoes vs. types of shoes.) This is best captured in C

A. It has increased the average lifetime of products.
B. It has resulted from retailer's attempts to predict demand more accurately and

C. It has decreased the use of flexible manufacturing by companies.
D. It has not increased the expense of keeping inventory of certain products.
E. It has not prevented companies from predicting aggregate demand with some certainty.

OA: E Why not B
Again, we can go back to the end of the passage: 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.

So we're told explicitly that companies are good at predicting aggregate demand. This is what we get from E

B isn't consistent with what we're told. It's the frequent introduction of new products that has led to the proliferation of SKU's, not attempts to accurately predict demand.

OA:D Why not A
We get the answer here: 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.

A is incorrect because the reduced average lifetime is an effect of the growth in new products, not a cause.
