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?
Unlike paint, the film gives a milky tone to certain colors.
At the end of its useful life, the film can be removed much more quickly than paint can.
The film can be applied only by technicians who have received special training.
The metal exteriors of airplanes have to be protected from high temperatures and caustic chemicals such as exhaust gases.
Even at speeds considerably higher than the normal speed of a passenger jet, the film remains securely attached.
错选的是E，很多人说是与方案无关我觉得是不对的，因为如果有了E，那么这个方案的可行性就加强了，即film可以满足飞行要求，故可以用于飞机上，故可以减少维护时间。但从另外一面想，如果将E取反是否会削弱这个推理呢？不会，所以E有些勉强
回到B，B我认为也是很勉强的，因为B说的是在产品寿命到期的时候取下来快，但是题干中的信息是paint都是在飞机需要maitainance的时候做的，很容易推理出maintainance的频率是更高的，不然航空公司就需要单独做paint而不maitain，因此基本上在做maintainance的时候产品寿命没有到期，B也就排不上用场。
所以这道题个人认为是不太严谨的，建议看个热闹就行
