32. Groups have "methods of preserving egalitarianism by ensuring that disparities of status don't arise."

36. The passage says societies like the !Kung were normal "until a few thousand years ago," but never suggests anthropologists are mistaken about this — NOT GIVEN.

39. The passage doesn't compare how strongly negative traits show up across different modern cultures — NOT GIVEN.
