Question

read the excerpt from hemingways 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.
the casual behavior of the characters during a difficult time demonstrates hemingway’s belief that a hero should
exhibit grace under pressure.
recognize the meaninglessness of life.
have a mentor to follow.
learn from his mistakes.

Explanation:

The excerpt shows characters acting casually (drinking, friendly interaction) before an attack (a difficult situation). Hemingway's concept of a hero often involves "grace under pressure"—remaining composed in adversity. The other options don't fit: recognizing life's meaninglessness (existentialism, not this context), having a mentor, or learning from mistakes aren't supported here.

Answer:

A. exhibit grace under pressure.
