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.
(E) The phrase “energetic disassembly” is not necessarily out of place in describing a controlled rather than an accidental explosion.
the key is "A",however, I cannot understand A's meaning. could anyone help?thx.

12. An advertisement designed to convince readers of the great durability of automobiles manufactured by the Deluxe Motor Car Company cites as evidence the fact that over half of all automobiles built by the company since 1970 are still on the road today, compared to no more than a third for any other manufacturer.
Which of the following, if true, most strongly supports the advertisement’s argument?
(A) After taking inflation into account, a new Deluxe automobile costs only slightly more than a new model did in 1970.
(B) The number of automobiles built by Deluxe each year has not increased sharply since 1970.
(C) Owners of Deluxe automobiles typically keep their cars well maintained.
(D) Since 1970, Deluxe has made fewer changes in the automobiles it manufactures than other car companies have made in their automobiles.
(E) Deluxe automobiles have been selling at relatively stable prices in recent years.
不明白为什么选B,他每年造的车子数目没有大的增长，和她的durability有什么关系啊。

14. Advertisement: Of the many over-the-counter medications marketed for the relief of sinus headache. SineEase costs the least per dose. And SineEase is as effective per dose as the most effective of those other medications. So for relief from sinus headaches, SineEase is the best buy.
Which of the following, if true, most seriously weakens the argument above?
(A) Most of the over-the-counter medications marketed for the relief of sinus headache are equally effective per dose in providing such relief.
(B) Many of the over-the-counter medications marketed for the relief of sinus headache contain the same active ingredient as SineEase.
(C) People who suffer from frequent sinus headaches are strongly advised to consult a doctor before taking any over-the-counter medication.
(D) An over-the-counter medication that is marketed for the relief of symptoms of head cold is identical in composition to SineEase but costs less per dose.
(E) The per dose price for any given over-the-counter medication marketed for the relief of sinus headache is higher for smaller packages than it is for larger packages.
我觉得应该选E,因为D里面说的是relief of symptoms of head cold,这个和relief of sinus headache是一样的吗？没有任何一句话表明两个东西是一回事儿啊？[em40]

8. What A says is simply that the benefits of using the word explosion outweigh the drawbacks. Since the argument recommends the use of that word, A must be true.fficeffice" />

12. Explained a couple of days ago in another post. Pls look for it. 14. The word "identical". E is irrelevant as the argument says SineEase is as effective per dose as the most effective. What E indicates is that larger package is cheaper per dose, or there is a discount for larger package. It is true to all drugs. I see no connection with the argument.
