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.
ans B
這題好奇怪阿 我的想法是
他是要我們weaken argument
所以是要找 即使削價競爭長久下來仍舊有利潤
那從B選項 哪裡可以看得出來呢?
