13.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 strat-egy is that forager societies are extremely varied. Indeed, any forager society with which anthropologists are familiar has had considerable contact with mo-dern nonforager 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.

有疑问的是B,如果古代的社会也跟现代有接触，那么这种strategy不是可行的吗？

B是加强，证明了现在的社会已经改变了，经过过渡和融合其他部落的特点，和古代的联系就变少了。A讲的就是随着时间，这些重要的特点并没有改变。

不过，我记得这个好像是OG上的题吧～
