Final answer:
True, C. Wright Mills' concept of the sociological imagination, which connects individual experiences with the wider societal context, is indeed his most significant sociological contribution.
Step-by-step explanation:
True, C. Wright Mills' greatest sociological contribution is indeed his concept of the sociological imagination. Mills described the sociological imagination as an awareness of the relationship between an individual's personal experiences and the wider society.
This concept helps to understand how personal challenges are connected to larger social issues and enables one to view one's own life within the context of history and the societal structures that influence it. For example, the decision to marry is influenced by individual emotions and, at the same time, is shaped by the social norms and the historical context of the institution of marriage.
Thus, the sociological imagination is a critical tool for sociologists to analyze and interpret the interplay between individual biographies and the larger societal patterns that influence them.
