Anthropologist Marc Edelman's study of rural peasants in Costa Rica as they responded to the economic and political upheavals brought about by civil war and increased debt demonstrate what aspect of human response to the state?

Agency

Explanation:

This is an example of the "agency" of humans against the state. Agency is an important concept in anthropological studies. Agency refers to the capacity of individuals to act independently and to make their own free choices. This is generally discussed in opposition to the concept of "structure." It is often a matter of debate how the forces of agency vs. structure operate in various social situations.
