题目：xdf阅读63篇第九篇讲free market的那一篇的第一题，问的是The primary purpose of the passage is to

这不是一道难题，总结上下文就可以选出正确选项E: argue that price-fixing, in one form or another, is an inevitable part of and benefit to the economy of any industrialized society

可是问题在于对这道题，新东方的主体题型解法失效了，xdf关于主体题的说法是：ETS出主题题的主要依据是：1、整篇文章的第一句 2、文章每一段的第一句 3、文章的主题句和结尾句 4、长段落每段首句与末句

可是这道题的明显这四个主要依据都是派不上用场，是我们根据上下文总结出来的。我发现新东方无论是面授课堂还是网络课堂所讲解的题目，都是贴合他们解题套路的典型题，而事实上我们在解题过程中有相当的题目是根本无法使用新东方理论的。

或许管卫东的“答案是比出来”才是对的，希望大家都来讨论讨论.

哪一句是主题句呢？

是“Accordingly, it requires a major act of will to think of price-fixing (the determination of prices by the seller) as both “normal” and having a valuable economic function. In fact, price-fixing is normal in all industrialized societies because the industrial system itself provides, as an effortless consequence of its own development, the price-fixing that it requires. ”这两句吗？

如果是，我想则基本可以判断选项正确了。
