A product that represents a clear technological advance over competing products can generally command a high price. Because <b> technological advances tend to be quickly surpassed </b> 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 <b> large profits on the new product will give competitors a strong incentive to quickly match the new product' s capabilities </b>. 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? ['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.', '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.', '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.', 'The first is a consideration raised in support of a strategy the argument endorses; the second presents grounds in support of that consideration.']
