Final answer:
All three elements—emotions, main characters, and a legacy—could be part of someone's life story, making the answer 'd. three'. Sociologists study all aspects of people's lives, and an individual's life course includes many stages and experiences.
Step-by-step explanation:
The three elements mentioned: emotions, main characters, and a legacy, could all be part of someone's life story. Therefore, the correct answer to the question is d. three. The life story of an individual can certainly include emotions that they've experienced throughout their lives, the main characters who have played a significant role in their personal narrative, and the legacy they leave behind, which could be a summation of their life's impacts and accomplishments.
Moreover, sociologists like Berger are interested in both monumental moments in people's lives and common everyday life events, indicating that they would study all aspects of someone's life story, including emotions, characters, and legacy. The life course of individuals within a culture is not just about the average age people in that culture may die or the lessons they must learn; it encompasses the various stages and experiences that constitute an individual’s existence within their cultural context.
