再问PREP-2-23,和gwd有冲突

23.   (28303-!-item-!-188;#058&003943)

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 maximum possible price for 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 a consideration that has been raised to argue that a certain strategy is counterproductive; the second presents that strategy.

(B) The first is a consideration raised to support the strategy that the argument recommends; the second presents that strategy.

(C) The first is a consideration raised to explain the appeal of a certain strategy; the second presents that strategy.

(D) The first is an assumption, rejected by the argument, that has been used to justify a course of action; the second presents that course of action.

(E) The first is a consideration that has been used to justify pursuing a goal that the argument rejects; the second presents a course of action that has been adopted in pursuit of that goal.

答案是C，那说明BF1是说明BF2的了？那中间的but如何解释呢？

再看GWD-1-3,划了不同的线

Because technological advances tend to be quickly surpassed and companies want to make large profits while they still can, many companies charge the maximum possible price for 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.

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.

这两个题不是有矛盾么？

第一个不理解，c第一句对的，但第二局应该不队阿
