Answer:

Why might some civilizations not have been part of the Neolithic Revolution?
butalik [34]
I’d say C.

A doesn’t make sense, they definitely could’ve domesticated animals in that time.

B doesn’t make sense either, they could’ve easily seen smoke signals, the sky wasn’t filled with them often.

C is just a weird answer. I doubt they were “passive observers” but probably the best answer to the question.

D doesn’t add up because they definitely needed agriculture/food surpluses. They were always hunting, they obviously ran out of food rather quickly.


So C is the answer.
