Question

read the excerpt from a farewell to arms.
the major asked me to have a drink with him and two other officers. we drank rum and it was very friendly. outside it was getting dark. i asked what time the attack was to be and they said as soon as it was dark. i went back to the drivers. they were sitting in the dugout talking and when i came in they stopped. i gave them each a package of cigarettes, macedonias, loosely packed cigarettes that spilled tobacco and needed to have the ends twisted before you smoked them. manera lit his lighter and passed it around. the lighter was shaped like a fiat radiator. i told them what i had heard.
in the passage, hemingways characterization of the narrator and his peers
provides important details about their backgrounds.
allows the reader to fill in the details without being given all of the information.
slows down the narrative to allow the reader to reflect on the meaning.
develops only one character at a time to not overwhelm the reader.

Explanation:

Hemingway's writing style here is sparse, giving minimal details (like the cigarettes, lighter) and letting readers infer more about characters. The first option is wrong as backgrounds aren't detailed. The third is wrong as the narrative isn't slowed for reflection. The fourth is wrong as multiple characters are interacted with (drivers, Manera). So the correct idea is that readers fill in details with the given sparse info.

Answer:

B. allows the reader to fill in the details without being given all of the information.
