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.
答案选B,可是俺怎么也别不过劲儿~~B是怎么削弱的呢?

文章说为了弥补之前降价的损失,航空公司会增加票价从而给了竞争者降价的机会B
B说,一旦有新的竞争者出现,航空公司还会降价,也就不会因为票价上升而让竞争者受益了。很好的削弱
