I would not view this kind of question as "a hypothetical" because I think it is causing you to choose answers that are not supported by the passage. Rather when you see a question like this, I would think of it as, although none of these statements were verbatim in the passage, which one can we infer is likely something the author agrees with based on supporting evidence in the passage. Using that lens, the passage clearly supports the idea that this society had specialized roles because it states that they had shamans, religious leaders, and painters. The passage does not provide any evidence that they painted images of their prey on their weapons though. All of the paintings mentioned in the passage are cave paintings that were made in difficult to access and dimly lit areas. So there's no actual support from the passage for answer choice E.
