Final answer:
Hemingway's use of minimal yet impactful details in characterization allows readers to infer and imagine the backgrounds and personalities of the characters, particularly noticeable in scenes involving officers and shared experiences around alcohol.
Step-by-step explanation:
In Hemingway's narrative approach, the characterization of the narrator and his peers is executed through minimal yet impactful details, allowing the reader to glean insights into the characters' worlds and personalities. Instead of providing extensive background information, Hemingway allows for a certain level of inference, enabling the reader to fill the gaps and craft a nuanced understanding of each character. This technique creates an authentic atmosphere and connects readers to the era in which the officers and other characters come to life through their actions and dialogue.
The provided passages from various literary works demonstrate the common practice of using alcohol and camaraderie as a means to build rapport and develop characters. Hemingway, with his signature economy of words, captures moments of shared experiences among characters that reveal their conditions, relationships, and the setting they inhabit. This approach can be seen as allowing the reader to fill in the details without being given all the information about the characters' backgrounds.
