Ca_teran asked "Question 22 to me e was better"
The question stem is weird, asking us what the author would encourage certain anthropologists to do.
We have to get this from the language of line 14: "failed to consider".
Since the author calls out some anthropologists for failing to consider two things, we can infer that the author would encourage them to consider those two things:
1 - modern hunter-gatherer societies are more sophisticated than earlier societies would have been in terms of tools, language, strategy, shelter, etc.
2 - modern hunter-gatherer societies don't deal with as many large animal predators as earlier societies did
Which answer sounds something like one of these?
(C) seems to be the only one that relates to appreciating the contrast between modern hunter-gatherer societies and early hominid hunter-gatherer societies, so it's the closest thing to the two points the author thinks these anthropologists failed to consider.
(A), (B) and (E) are all about how the anthropologists should analyze modern hunter-gatherer societies. (D) only involves comparing modern ones to those from the previous century. But the whole point/context of this question and line 14 is our author grumbling that anthropologists make inferences about prehistoric societies by observing modern ones (and the author thinks that this is dumb, since there are important differences between modern and prehistoric hunter-gatherer societies).
Hope this helps.
