This is unsupported. The second camp focuses on systems of meanings, but nothing suggests that this focus comes at the cost of overlooking anyone’s humanity. The topic of subjects’ humanity isn’t raised by the author at all.

This is anti-supported. Some anthropologists understand systems of behavior as responses to an environment, but the author rejects the idea that any single camp has the "only" correct perspective.

This is strongly supported. Although anthropologists disagree over their approaches, the author says they should actually employ multiple approaches in combination. This requires that at least these three approaches are all compatible with each other.
