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.

Can somebody please explain this?

Is the answer A?

"A" because it shows that even though forager societies are varied, they all still have common, non-modern elements that lend themselves to study by anthropologists.
