8.     Any serious policy discussion about acceptable levels of risk in connection with explosions is not well served if the participants fail to use the word “explosion” and use the phrase “energetic disassembly” instead. In fact, the word “explosion” elicits desirable reactions, such as a heightened level of attention, whereas the substitute phrase does not. Therefore, of the two terms, “explosion” is the one that should be used throughout discussions of this sort.

Which of the following is an assumption on which the argument above depends?

(A) In the kind of discussion at issue, the advantages of desirable reactions to the term “explosion” outweigh the drawbacks, if any, arising from undesirable reactions to that term.

(B) The phrase “energetic disassembly” has not so far been used as a substitute for the word “explosion” in the kind of discussion at issue.

(C) In any serious policy discussion, what is said by the participants is more important than how it is put into words.

(D) The only reason that people would have for using “energetic disassembly” in place of “explosion” is to render impossible any serious policy discussion concerning explosions.（A）

(E) The phrase “energetic disassembly” is not necessarily out of place in describing a controlled rather than an accidental explosion.

请问D为什么不对？人们用energetic disassembly使严肃的讨论变得不可能，也就是说在讨论严肃问题的时侯不用了，不正好是个假设吗？A中只是说explosion的优点多，但并没有涉及到energetic disassembly啊？迷惑， 不知道想的哪不对，请牛牛指点！！！多谢

先必须锁定文章的结论：必须使用explosion。

把A取非，缺点大于优点，那还用explosion干吗，跟文章结论相反了，矛盾。所以A是答案。

D有一个明显的错误：only。文章没有出现绝对化的词语，选项就不应该出现绝对化的词语。其次，D是一个加强，不是一个假设。

A--> B

假设说得是A和B之间有那么一种关系，使得A-->B，加强的范围更广，只要有助于B成立的都可以认为是加强。

不过本题还是觉得LAWYER-L所的好
