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.

(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.

16. (26678-!-item-!-188;#058&003277)

When an airplane is taken out of service for maintenance, it is often repainted as well, and during the repainting no other maintenance work can be done on the plane.  In order to reduce maintenance time, airline officials are considering using a new nontoxic plastic film instead of paint.  The film takes just as long to apply as paint does, but many other maintenance tasks can be carried out at the same time.

Which of the following, if true, is further evidence that using the film will help the airline officials achieve their goal?

(A) Unlike paint, the film gives a milky tone to certain colors.
(B) At the end of its useful life, the film can be removed much more quickly than paint can.
(C) The film can be applied only by technicians who have received special training.
(D) The metal exteriors of airplanes have to be protected from high temperatures and caustic chemicals such as exhaust gases.
(E) Even at speeds considerably higher than the normal speed of a passenger jet, the film remains securely attached

16题：
当飞机停工维修时，需要经常重刷，在重刷的时候其他维修工作无法进行。
为了减少维修时间，决定用贴膜film,这种薄膜花费时间和刷漆一样，但是其他维修工作却可以进行。
B选项，如果去除薄膜时间比油漆慢，那么下次维修时的维修时间岂不是要增加。（因为费劲需要经常repaint的）

不对，15题题目应该是削弱题吧

楼主15题的问题可以贴上来吗？是加强结论吗？
