Instead of blaming an airline accident on pilot error, investigators should find out why the error was made by analyzing airplane design, airline management, and pilot-training programs. For only then can changes be made to ensure that the same type of error does not recur and cause another accident.


Which of the following is a presupposition of the argument above?

(A) Pilot error is not a contributing factor in most airline accidents.

(B) Airline companies themselves should be the agents who investigate airline accidents.

(C) Stricter government regulation of airline companies will make air travel significantly safer.

(D) Investigators of airline accidents should contribute to the prevention of future accidents.


(E) Most pilots who make errors in flying will repeat their errors unless they are retrained.


the key: D。why not A?

如果是A的话，那么主要原因不是pilot，但也没必要继续找出真正的error所在，因而只有C的提出，才会促使investigaters去发现调查出真正的原因然后避免同样的事故在发生。

文章的意思是指责犯错的驾驶员是没意义的，调查人员要从XXXX去调查研究，只有这样才能避免以后出现类似的情形。如果D不成立，那么调查人员根本没必要去关心是否要避免以后的事故，也不需要去调查XXXX。A的错误是明显的，因为文章讨论的不是事故的原因而是避免以后事故的方法，而且文章开头也暗示了指责驾驶员是没意义的，而没说错误不是驾驶员犯的
