求教：假设（assumption）中的GAP和他因排除

DORIS807

看了LAWYER的关于实战的帖，自己也做了一些题。发现在assumption的部分，总是在他因排除和加强（用gap）的时候出错。我想问，用lawyer在假设中提到的那个加强（有GAP的方法），前提是不是结论中出现新元素？因为有时候用“无关新词排除”的时候，我会排除选项中的新名词，所以我想确定一下，lawyer说的这种假设中的gap，是不是指在原文中的结论，或者前提里有新名词。麻烦哪位NN来帮帮我。谢谢

补充一点，有没有哪位可以讲讲assumption里面无关词排除法，本人常在此踩地雷，谢谢啦

额，还是我自己来解决吧。希望有战友来看看我是不是有哪里想的不对。一道prep的老题
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.
做题的时候我选的是D，因为我觉得既然protect了exterior了，那么肯定不需要经常maintenance，所以就reduce time。MS FORUM上说，D是无关选项，理由有两个
第一，issue讨论的不是protecing exterior plane和reduce maintenance的问题，而是paint和film两个概念在减少维修时间上的关系。也就是看两种东西，哪一个能更好的proetecting exterior plane（硬要和D扯上关系的话）
第二，退一步说，即使D选项的陈述成立，也是doesn't have anything to do with the comparative maintenance between the plastic and the paint
综上所述，我现在对无关选项的理解（虽然这题不是假设）也就是说如果一个选项不能和陈述的论据有直接的联系，而做了进一步的推测，那就不是正确的。
其实我有点明白，不知道是不是表述的不正确，不精准。还是希望有战友来说说

新东方的老师确实也是这么说的.

先问一下这道题选的是不是B呀~
