In the excerpt from Hemingway's "A Farewell to Arms," the narrator reveals that he interacts easily with both his superiors and the drivers. This is evident from his willingness to have a drink with the major and two other officers, as well as his conversation with the drivers in the dugout. The narrator's actions of sharing cigarettes with the drivers and informing them about what he had heard also indicate a sense of camaraderie and connection with them, showing that he doesn't look down on anyone involved in the war, whether officers or enlisted men.
Therefore, the correct answer to the question "What does the excerpt reveal about the narrator?" would be:
- He interacts easily with both his superiors and the drivers.
