Miranda has not eaten any food for the last three days. She has lost so much weight recently that her bones are showing through her skin. Even then, when Miranda looks in the mirror, she sees a person who needs to lose another ten pounds. This behavioral pattern is MOST consistent with:

a punishment or the threat of punishment used to enforce conformity. enforcement of norms or shared rules of conduct that tell people how to act in specific situations. social control. not everyone internalizes all of society's norms, and some people must be motivated by self-fulfillment.
