Some airlines allegedly reduce fares on certain routes to a level at which they lose money, in order to drive competitors off those routes. However, this method of eliminating competition cannot be profitable in the long run. Once an airline successfully implements this method, any attempt to recoup the earlier losses by charging high fares on that route for an extended period would only provide competitors with a better opportunity to undercut the airline's fares.
Which of the following, if true, most seriously weakens the argument?


A In some countries it is not illegal for a company to drive away competitors by selling a product below cost.
B Airline executives generally believe that a company that once underpriced its fares to drive away competitors is very likely to do so again if new competitors emerge.
C As part of promotions designed to attract new customers, airlines sometimes reduce their ticket prices to below an economically sustainable level.
D On deciding to stop serving particular routes, most airlines shift resources to other routes rather than reduce the size of their operations.
E When airlines dramatically reduce their fares on a particular route, the total number of air passengers on that route increases greatly.

请问大家这个B选项是怎么理解的呀？句子是想说long term profitability 还是 drive competitors off 呢？

不矛盾，B选项说的是，如果你干过一次杀价的勾当，竞争者会退出市场，他们退出之后你把价格调回去就行了，不用担心他们再来，因为竞争者认为只要你干过一次就会干第二次，所以以后他们就不来争这个市场了。
