BF根据原文结构和框架，快速解决得到答案！

今天，我看了GWD分析，自己摸索能够快速解决BF的方法！

因为我发现很多BF都有一个转折词，however，yet，but，although等，还有consequently，therefore，since，because等因果词。

比如：GWD-12  Q33:


Several of a certain bank’s top executives have recently been purchasing shares in their own bank.This activity has occasioned some surprise, since it is widely believed that the bank, carrying a large number of bad loans, is on the brink of collapse.Since the executives are well placed to know their bank’s true condition, it might seem that their share purchases show that the danger of collapse is exaggerated.However, the available information about the bank’s condition is from reliable and informed sources, and corporate executives do sometimes buy shares in their own company in a calculated attempt to calm worries about their company’s condition.On balance, therefore, it is likely that the executives of the bank are following this example.



In the argument given, the two boldfaced portions play which of the following roles?

1. The first describes the circumstance the explanation of which is the issue that the argument addresses; the second states the main conclusion of the argument.
   
   
2. The first describes the circumstance the explanation of which is the issue the argument addresses; the second states a conclusion that is drawn in order to support the main conclusion of the argument.
   
   
3. The first provides evidence to defend the position that the argument seeks to establish against opposing positions; the second states the main conclusion of the argument.
   
   
4. The first provides evidence to support the position that the argument seeks to establish; the second states a conclusion that is drawn in order to support the argument’s main conclusion.
   
   
5. Each provides evidence to support the position that the argument seeks to establish.
   
   

原文框架：1，先是讲了一些background information或者一些facts或circumstance，然后就来了好几个since来解释前文，即第一种解释，2，接着来了一个however，在however那句就讲了一个解释，接着就来了一个On balance, therefore,…



从原文框架可以判断，要排除C,D,E，因为他们的the first 都是说the argument seeks to establish，明显是错的，因为the first是在however后面的，所以肯定是oppose或against或refute的。剩下A,B，因为B的the second说是一个结论，那个结论是为主要的结论提供支持的，所以不正确，因为therefore只有一个结论。



从GWD-5# Q19，GWD-10#Q17，GWD-12#Q33，GWD-24#Q24的therefore可以看出，凡是therefore后面的都是conclusion。

欢迎讨论！

我本人，边看边想逻辑的原文结构，看出两个相反的观点，然后根据BF的位置

来判断，就很快可以排除一些明显错误的选项！
