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?

1. All forager societies throughout history have had a number of important features in common that are absent from other types of societies
2.Most ancient forager societies either dissolved or made a transition to another way of life
3.All anthropologists study one kind or another of modern-day societies

4.Many anthropologists who study modern day forager societies do not draw inferences about ancient societies on the basis of their studies.

5.Even those modern-day forager societies that have not had significant contact with modern societies are importantly different from ancient forager societies
