Test2-15. (25986-!-item-!-188;#058&002914) 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. 這題答案是B 我選D 我選D的原因是 原文說有航空公司為了要讓某時段的競爭者退出這個時段 會採用降價方式 甚至為了趕走競爭者不惜降價讓自己虧損 然後獲勝的公司為了彌補之前的虧損 會把票價提高 這時候 競爭者會趁這個好機會降價來搶走對方的客源 我選D是覺得 D指的是如果一個公司決定退出這個航班 會把這個航班的資源移轉到別的航班 不只是縮小這個航班的size 這時候 原本獲得勝利的廠商就獨占整個市場 可以任意調高價錢 不知道我想的會不會太遠 還是解讀錯誤.... B選項給我的感覺好像是支持選項.... 新競爭者出現 原本勝利的廠商會用同樣的方式在對付他 感覺比較像支持原來的Argument this method of eliminating competition cannot be profitable in the long run 請各位幫我看看~~~ 謝謝~~~~^^ --
