支持B.
原文有两个strategy. 1) charge the greatest price the market will bear when they have such a product. 2) charge less than the greatest possible price. B: 前半句的 a certain strategy指charge the greatest price. 后半句的that strategy指前半句的a certain strategy, 即charge the greatest price. 所以完全吻合原文.
A: 前半句正确. 后半句中course of action endorsed by the argument是指charge less than the greatest possible price, 而第二个boldface是支持 this course of action, 不是the course of action本身. 故错. C: 前半句正确. 前半句中assumption指technology advances tend to be quickly surpassed, a certain strategy指charge the greatest price. 后半句不应该是cast doubt on that assumption, 应是cast doubt on that strategy. D: 前半句错. 应该是support of a strategy that argument criticizes, not endorses. 后半句建立在前半句错误上, 错上加错. E: 前半句正确. 前半句中a certain strategy指charge the greatest price. 后半句的that strategy指前半句中的a certain strategy, 即charge the greatest price, 故错. 后半句应是: explain the reason of a NEW strategy.
