1 Premise：顾客稀饭高桌子高凳子，呆的时间比坐普通凳子顾客短

TRUF专栏：
看原文：找出结论和推出该结论的前提。特别注意结论的特殊性和具体性。
找答案：用结论的具体性去区分有关无关，并结合TEST。对于特殊类，先预测出答案，用此预测去找答案
TEST：问自己，是否该答案使作者再考虑他的观点或迫使作者做出反应或原文该前提能证明该结论吗。
几种特殊类型：
原文前提和结论关系不密切：正确选项直接WEAKEN结论
因果型结论：即原文给出两件事，然后得出结论说是一件事（因）导致另一件事（果）。WEAKEN该结论
的方法包括：A。是其他原因或可能导致该结果。B。割断因果：或有因无果或有果无因。C。因果颠倒了。
D显示因果关系的资料不准确。
条件型结论：结论带条件（即为充分必要）。WEAKEN的方法显示充分条件成立，必要条件可以不成立。
或举反例，或提供有关信息。
原文是类比：WEAKEN方式为两者本质不同
调查：有效性受怀疑（被调查的没代表性等）
第一步：看问题问什么。Which of the following, if true, is most damaging to the position of the cable-television spokesperson?
第二步：分析原来文章内容。Conclusion：Subscriptions to cable television are a bargain in comparison to “free” television.
Premise：“free” television is not really free。It is consumers, in the end, who pay for the costly advertising  that supports “free” television。
第三步：找答案。先排除无关选项（用具体性和特殊性）（A）选型。买不买电视机和题目结论完全没关系，排除。（C）选项，电视机画面质量也没有关系。（E）可以选择电视机频道根本和题目结论没有任何关系
第四步：剩下2个选项。因果型结论：即原文给出两件事，然后得出结论说是一件事（因）导致另一件事（果）。WEAKEN该结论
的方法包括：A。是其他原因或可能导致该结果。B。割断因果：或有因无果或有果无因。C。因果颠倒了。D显示因果关系的资料不准确。
我们来看：consumers pay advertising  that supports “free” television------------------Subscriptions to cable television are a bargain in comparison to “free” television.
    两者相比较，只要切断之间因果关系就可以了。如何切断因果？只要将2者比较之间具有相同情况就可以了。我们来看这题。只要两者都 pay for the costly advertising。那么就可以削弱原结论。答案就是D。
TEST：问自己，是否该答案使作者再考虑他的观点或迫使作者做出反应或原文该前提能证明该结论吗。

Background: the use of herbicides will make crops grow efficiently
Premise: but a kind of bird was found decreasing, the scientists claim that the increasing use of herbicides make the birds poisoned
