关于题目中Conclusion的解释，是属于P还是C？

syla914

有一些题目在给出conclusion的时候经常解释原因，这个原因是P还是C呢？

它是类似于一个附加信息，和做题并没有太大关系吗？因为感觉做题主要还是抓住P和C

欢迎讨论

附一个例题：Some anthropologists study modern-day societies of foragers in an effort to learn about our ancient ancestors who were also foragers. A flaw in this strategy is that forager societies are extremely varied. Indeed, any forager society with which anthropologists are familiar has had considerable contact with modern, non-forager societies.
Which of the following, if true, would most weaken the criticism made above of the anthropologists` strategy?
A All forager societies throughout history have had a number of important features in common that are absent from other types of societies.  
B Most ancient forager societies either dissolved or made a transition to another way of life.  
C All anthropologists study one kind or another of modern-day society.
D Many anthropologists who study modern-day forager societies do not draw inferences about ancient societies on the basis of their studies.  
E Even those modern-day forager societies that have not had significant contact with modern societies are importantly different from ancient forager societies.

此题中，C 是 forager societies are varied。Indeed 那句话是C里面的P，也就是说是一个补充说明。
