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 mew product will give competitors a strong incentive to quickly match the mew 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.
答案是B
BC琢磨半天,我認為問題出在紅色字上
因為 because後接的粗體字,在解釋第一句話,而不是證明第一句話
我們都會用because解釋原因的 ,不是嗎?
至於but後接的粗體字,我想BC選項畫線部份都表示某程度的反駁 ,不是排除重點
