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 withmodern, non-forager societies. Which of the following, if true, would most weaken the criticism made above of the anthropologists’ strategy?
只是对两个选项有疑问：
(A)  All forager societies throughout history have hada number of important features in common thatare absent from other types of societies.
(D)  Many anthropologists who study modern-day forager societies do not draw inferences about ancient societies on the basis of their studies.

答案是A，理由是This statement properly identifies the factor that weakens the argument: A comparison could well be a valuable source of understanding if all foraging societies are shown to share certain features not found in other societies.
但我觉得D更好。问题是哪个选项most weaken the criticism of the strategy，这里的strategy是study modern-day societies of foragers in an effort to learn about our ancient ancestors。D选项说的是do not draw inferences，说anthropologists没有采用inference这种strategy（注意inference只是study的一种strategy，还有很多另外的strategies）；如果没有infer，那用来study的就是其他的strategies，这些策略并不一定存在和inference strategy一样的问题，因为题干中提出的variety、connection只有在人们根据modern外推至ancient时才会出现问题。
Is it right?

Thank you!

题干里criitcism指出各个forage 间很大不同，而只有A能削弱这种批评：指出各个forage虽然很多地方不同，但还是共有一些关键特征的。
并没有看出来D哪里削弱了。

D很明显是无关选项
