Final answer:
The in-depth back story of characters in the first section of 'In Cold Blood' serves as an example of characterization, providing insight into their personalities and motives.
Step-by-step explanation:
The first section of Truman Capote's In Cold Blood providing an in-depth back story of the characters is an example of characterization. This technique is important in literature as it gives readers insight into the characters' backgrounds, motives, and personalities, helping to build a connection to them and understand their roles within the story.
Characterization often includes anecdotes or background information that contribute to a deeper understanding of the characters. In the case of non-fiction, such as In Cold Blood, it may also involve providing historical context or facts to support the narrative. This approach adheres to the Editing Focus discussed in Section 4.6, which emphasizes the development of relatable characters and a consistent point of view.
The detailed descriptions also align with the importance of setting and sensory details to help readers visualize the characters in a particular context. By providing these details, Capote ensures that the narrative maintains focus on the central narrative and offers an organized sequence of events, furthering the readers' engagement with the story.
