Answer:
1. Carter Druse - daring
2. Carter's father - stern
3. the Federal officer - imaginative
4. the commander - understanding
Step-by-step explanation:
"A Horseman in the Sky" is a short story by Ambrose Bierce set during the American Civil War. The main character is Carter Druse, who we can characterize as daring. Carter decides to betray his state and fight for the Union, which was bold and dangerous. His father is a stern, rigid man. He is thoroughly disappointed in his son's choices. The Federal officer who thinks he has seen a sign form Heavens is quite an imaginative man. Finally, the commander who listens to the officer's story is an understanding man. He knows the officer's interpretation of what he has seen is absurd, but he does not say anything.
In the story, Carter Druse ends up having to shoot his own father on the field, since they are on opposite sides.
