非常贴切的证明选选项一定要切合conclusion，不然分分钟掉进陷阱
premise:the customers are usually change carpets in the specific time of their life.
conclusion:so the carpet company can only earn money by purchasing other company but not marketing their products
bg info:the carpet company can hardly expand the market
prephrase:weaken--->the company can increase market share by marketing/purchaing other companies cant increase either.除了两种都不行之外，还有“另外一种方法这样的思路”

Akept for the first round.irrelevent to the carpet
Birrelevent to the new brands
Cirrelevent to the profit
Dright这是一个increase market share的另一种方法
Eirrelevent to the market share

补昨天关于第一道题的解释
As you should have noted while reading, the conclusion contains a conditional indicator and is thereby conditional in nature.To attack a conditional statement you must show that the necessary condition is not actually necessary for the sufficient condition to occur.就是“只有……才”的题干，必须具备某条件才能成立的结论，这时候的反驳方法就是证明该条件并不能使其成立，或者说还有另外的条件。当然，前提是要知道到底是什么条件才能使其成立
2.--->29s
premise:in order to remove CO2
conclusion:the scientists have a plan that build a seedweed farm in the sea and the dead seedweed can burn to supply energy
prephrase:weaken--->the seedweed farm(plan) will not have any effect/will produce more CO2 than before.

3.--->43s
bg info:the rental decline about 10000
explanation1:because V rent and also sell cheaply so it occupy the market share the original one used to be
explanation2:not because of V, since V only rent 4000
prephrase:weaken explanation2--->it is V's charge/V's influence

Aright
Birrelevent
Cirrelevent
Dirrelevent
Eirrelevent
OA：E
错因：weaken point：exp2 think 10000 weighs more than 4000，就该点反驳，为什么数量小也能翻盘。其实在prephrase已经有了，就是V's influence is larger than rent。
*就算题目里面有关题目的名词一个字都没有提也不代表不相干！！

4.--->28s
explanation1---premiseur competitors' bottle shape is the same as us; conclusion: it is very likely that the customers will make mistakes.

Birrelevent
Cwrong
Dirrelevent
Eirrelevent

OA：E
错因：没读懂题目，info1---30% who placed order are subscribers that under 35. info2---most who placed order are under 35
E选项就是info2的改写
A选项因为不知道总人数，所以30%不能用

第一题我做错了。先开始选了B，因为忽略了结论是gain而不是确保当下的market share不会被侵蚀
然后我看懂题意后选了C，还是把market share 和revenue自动带入了。
最后认真考虑D，意识到这题的属性是目标导向题，也就是达到这个gain market share 的结果就好，不用太刻意区分在A或者B之间。

这题在我看来和前几天的彗星那道题很像：Although fullerenes--spherical molecules
因为在那道题的时候我的第一反应也是找另外一个能形成F的条件。
但是这两道题的区别在于类型不同，carpet 这道题是有be able to ，也就是目标第一，
而Fullernes那道题是说这个条件可以给地壳的形成条件做参照，是前提结论型，那就是要推翻前提为第一位。
