Answer:

The microsociological perspective helps us understand how large-scale social dynamics shape each  individual's life.

Explanation:

Microsociology is the part of sociology that deals with social action between individuals (social actors) in small social units (such as couple relationships or small groups) and fundamental “fine structures” in the interpersonal behavior. An example would be how social relationships develop from social action, how interactions in social relationships arise and persist from the tiniest hints of behavior in alternation between alter and ego, or how the consequences of social action constantly create new starting conditions for new social action.
