本题的启示：
1.无关的选项通常都是谈到一个相关的话题，但并非是结论中的中心。抓住结论的关键词（topic）无关的选项就会被排除，本题的无关选项是A。
2.shell game（小把戏，抑或叫诡辩） 的识别：通常这种把戏会针对结论中的细节下手，本题C项是将结论中的topic：gain market share 换成了 increase profits and revenues。另一种可能是这种诡辩会对推理的方向下手，本题C项就是将推理方向调换，如果并购，那么利润会上升。而结论中需要反驳的推理是如何证明gain market share--->purchase competitors 是错的。这在逻辑上将其实就是逆命题和命题的真假并不总是同步的。

If the seaweed is burned and producing carbon dioxide again,the plan fails.

BG:J said in 1994,the video rentals decline.
Premise:because the outlet sell videos cheaply,
Consquence:the rental declines.
another explanation:the quantity of video being sold is much less than the rental.
weaken Brass is strenghten Jennifer.
choice:E
A repeat the materials
B irrelevant information
C irrelevant information,so they buy videos in certain nights,and the total year's selling records are still not changed.
D irrelevant information,it has nothing to do with the way or the stimulus to buy videos.The key problem is why selling videos lead to the rental decline.
E correct.because selling videos will broadly decline the the number of potential customers who want to see videos.
本题启示：错选无关信息的选项常常是因为造成了错误的遐想。
克服错误的遐想的方式是：明确谈论对象，将对象间的逻辑简化。本题逻辑：反驳光碟卖出数量的上升无法填补出租数量下降。因此，辩论关键是证明光碟卖出数量是可以弥补出租数量下降的。

Marketing overseas in a new market?
(WRONG GUESS)
Didn't understand the key point of this question: market share.
Answers:
(A) "floor covering" is IRRELEVANT
(B) "no remaining niche for a new brand" IRRELEVANT - SUPPORT
This is an Opposite answer that strengthens the argument.
If there are no remaining niches to fill, then there is no way to expand other than
to purchase a competitor.
(C) "2/3 emerged companies declined in profit" explain the market is hard to get in, but doesn't doubt the conclusion. (Didn't understand Answer-C: MERGER-NOT imerge)
Answer choice (C) simply suggests that when companies purchase
their competitors the endeavor is often financially unsuccessful. Essentially,
answer choice (C) fails to prove that purchasing competitors is unnecessary to
gain market share.
(D) CORRECT
"the dominant company cut price through lower cost so that others leave the market" doesn't doubt the conclusion.
* Cutting down the cost -> Lower prices -> Competitors leaving -> Bigger market share
(E) CORRECT.If consumers increasingly follow the new patterns and styles.
"consumers are increasingly resistant (=reluctant) to new patterns and styles"
