C is wrong for using the verb "consitutes = form", the passage is about classifying

caterpillarcn

"consitutes = form"???
english is not equivalent to simple translating. Here, constitute means the same thing as qualify.

同意选C

并且我对文章结构的理解好像和队长差很多啊……

主题：没有一致意见

共识：关于P的基本定义。

差别:观点1、有人认为p response应该是unconscious

     观点2、p和o界定模糊，甚至把p归为o。而o是conscious的，与前一种观点的unconscious恰相反。

接下来开始解释p response not involve conscious odor perception。

证据：多数物种p通过VNO precess，而VNO独立于主要嗅觉器官。

但是又对这个证据qualify：不是所有动物p都经过VNO，也不是所有经过VNO的化学信号都是p。

举例：g蛇通过VNO detect and track prey。（这个之所以不算p，我感觉主要是因为它是不同物种之间。而前面p的定义是same species）

综上，作者也没有得出明确结论。只是提供了一些关于unconsesus的信息。主题题还是应该回到首句：There is no consensus among researchers regarding what qualifies a substance as a pheromone|
C. present some of the issues involved in the debate over what constitutes a pheromone

同意C这里的constitute是qualify的同意改写

请大家指点！！

感觉上C是不错。。至少题目第一句话就已经直接切入这篇文章的主题

第9题倾向选C，作者没那么强烈的想法去赞成某个观点，更多的是介绍目前的一些看法，最重要的是没有否定其中任何一个。

刚才还在郁闷，怎么看到的文章意思和答案全相反了呢，看到kathy的解释不由长长舒了口气~~~~

同意kathy8446的部分解释，主题题还是应该在文章的最前面或者开始，OG的主题题好象都很明显，看文章前面基本是比较清楚的
