求问一道gwd boldface

ALIC铃

A product that represents a clear technological advance over competing products can generally command a high
price. Because technological advances tend to be quickly surpassed and companies want to make large
profits while they still can, many companies charge the greatest price the market will bear when they have such a
product. But large profits on the new product will give competitors a strong incentive to quickly
match the new product’s capabilities. Consequently, the strategy to maximize overall profit from a new
product is to charge less than the greatest possible price.
In the argument above, the two portions in boldface play which of the following roles?
A. The first is an assumption that forms the basis for a course of action that the argument criticizes; the
second presents the course of action endorsed by the argument.
B. The first is a consideration raised to explain the appeal of a certain strategy; the second is a consideration
raised to call into question the wisdom of adopting that strategy.
C. The first is an assumption that has been used to justify a certain strategy; the second is a consideration
that is used to cast doubt on that assumption.
D. The first is a consideration raised in support of a strategy the argument endorses; the second presents
grounds in support of that consideration.
E. The first is a consideration raised to show that adopting a certain strategy is unlikely to achieve the
intended effect; the second is presented to explain the appeal of that strategy.
