I thought the conclusion should be the natural process study doesn't need plentiful of resources as the study and discoveries started under the condition of drought and hunger
The confusion in this question comes from distinguishing what the author has stated and the claims of "some anthropologists." The first sentence is stated by the author and is meant to be accepted as fact. We know that in 100% of cases study of natural processes requires leisure and leisure requires plentiful (not scarce) resources.
Additionally, we're told that the complex discoveries of early societies required the study of natural processes. This triggers the chain mentioned above (study --> leisure --> plentiful resources) and that's how we're able to prove answer choice C.
Essentially, the idea about drought and hunger is offered as background information meant to confuse you.
