What best explains social reality: structure and/or agency? Answer with reference to at least one approach and one empirical example

The agency-structure problem is often cited as the central problem in social and political theory (Carlsnaes, 1992:245). Pleasants (2009:885) affirms that this debate concerns ?the nature of the relation between human beings qua individual agents and the causality of the social systems, structures and forces that bear upon their condition of action?. Theorists try to find the best approach to understand and explain social reality.
