请教大家，ＯＧ１１th，CR第48题。

Some anthropologists study mordern-day societies of foragers in an effort to learn about our ancestors who were also foragres.A flaw in this strategy is that forager societies are extmely varied.Indeed,any forager society with which anthropologists are familiar has had considerable contact with mordern,non-forager societies.

请您指点一下，这道题目的逻辑分析过程。我愚钝，ＯＧ解释看不太懂。思路不清。

谢谢您的指点！

Merci

Situation :

果：studying contemporary foraging societies in order to understand ancient foragers is flawed .

因：societies改变了，并且由于当代的foragers与现代的非forage的社会接触太多。

有两个原因，一是由于societies varied；二是当代的foragers had much contact with modern societies。

要weaken，A说所有的forager societies had a number of important features in common。证明了situation中的果不成立，即可以通过研究contemporary foraging societies来了解ancient foragers。它weakened 第一个因，尽管社会varied，the common can be used in order to study the ancient societies.

不知道讲得清楚不。。。在逻辑区发帖有点班门弄斧了，我自己的逻辑还一团糟呢
