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 ost 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 error in flying will repeat their errors unless they are retrained.

我想选A啊，A那么明显啊有木有，为什么答案是D啊

大家交流一下，答案应该还是D的吧~
presupposition-也就是假设类，如果某选项取否使得原文也被否决了，那才是正确答案。
按A的说法，飞行员不用担负责任（飞行员的错误操作不是collision的主要原因），取否后是飞行员要负担主要责任，那么原文被否决了吗？没有，原文还说道training和以后不要犯同样的错，即使飞行员犯了错原文还是可行。
而D取否后事说investigation不用contribute，不contribute了干嘛还要training和避免以后的collision~~~整个argument就无意义了。
所以应该是选D的~
再讲多一点的话，如果这道题问的是strength 加强，那可能AD要争议一下而且搞不好A还会赢，这大概就是假设和加强的微妙关系~~~一定要分清楚哦~~~

首先，我建议LZ遇到问题之后，不要着急去提问，而是用一下搜索

这道题前辈有非常好的解答，我建议你去看一下~

我在这里还是给你讲一下吧~

逻辑结构是这样的：
should find out why the error was made ; only thenensure that the same type of error does not recur and cause another accident

那么也就是，find error 是因，避免是错误在发生是果
假设题的一个做法就是对选项取非，如果削弱argument，那么答案正确
选项D Investigators of airline accidents should contribute to the prevention of future accidents. 如果取非的话就是不应该contribute to the prevention，这一点跟文章的结论正好是相反的~

而如果选A Pilot error is not a contributing factor in ost airline accidents.取非的话就是飞行员的错误是factor 但这跟文章的逻辑没有关联

所以答案选D
