单选题 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 tort.
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.
E、 (E) The phrase "energetic disassembly" is not necessarily out of place in describing a controlled rather than an accidental explosion.

【正确答案】 A

【答案解析】[解析] Therefore前后分别为原因与结论，最后一句话实际上与第一句话相对应。因为“explosion”引出desirable的反应，而“energetic disassembly”不行，所以应使用“explosion”。假设的答案方向有三种：①A与B之间有联系；②引出desirable的反应的原因有意义；③没有其他原因影响使用“explosion”。如果论讨中，对“explosion”的合意反应优点超过缺点且若有缺点也是由于不合意的反应，正如(A)所说，就确实表明引出desirable的反应的原因有意义，即A可行或有意义，所以(A)正确；(B)、(E)无关；(C)起到了Weaken的作用；而(D)中的only属段落中未出现的绝对化语言，所以必错。
