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?
In some countries it is not illegal for a company to drive away competitors by selling a product below cost.
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.
As part of promotions designed to attract new customers, airlines sometimes reduce their ticket prices to below an economically sustainable level.
On deciding to stop serving particular routes, most airlines shift resources to other routes rather than reduce the size of their operations.
When airlines dramatically reduce their fares on a particular route, the total number of air passengers on that route increases greatly.
，E虽然说销售量上去了，但是学过商科的应该都知道简单的价格下降销售量上升并不能判断是否profitable。而B选项其实是一种博弈的看法。也就是说我担心我一旦提价其他竞争者会有更好的机会参与竞争，但实际上竞争对手不这么想，B选项就是站在竞争对手的角度，竞争对手会认为你之前打过价格战，那么如果我在你提价的时候再进入该市场，你依然会用同样的方法把我挤出去，所以我不会和你拼。这样造成的结果就是，虽然我提价了，但是竞争对手不会轻易参与竞争，于是提价之后自然就profitable了
