Which of the following is a central feature of sociology?

A central feature of sociology is the focus on social interactions, which encompass the ways individuals and groups relate to and influence one another within society. Sociology aims to understand how these interactions shape human behaviors, social norms, institutions, and cultures. The examination of social interactions allows sociologists to analyze patterns of behavior, including how social contexts impact individual choices and relationships. This foundational aspect underlines the importance of examining both micro-level interactions (like those between individuals) and macro-level interactions (like those among larger social entities), making it essential for understanding social structures and dynamics.

In contrast, while biological evolution, geographical factors, and the physical environment can all play roles in shaping human societies and behaviors, they are not the primary focus of sociology. These areas may intersect with sociological studies but do not fundamentally define the discipline itself. Sociology is specifically concerned with social relationships and their implications, setting it apart from disciplines that emphasize biological or environmental contexts.
