Answer: D. Both passages have a theme of the hardships of war.
Explanation: In both passages it talks about war.
In the first one, when it says "' I've just come from the Richmond camp with news about the revolutionaries...'" This is a clear statement about the revolitionary war, and further on it goes to say, "'Lieutenant Hamlin's horse came up lame, and he was unable to deliver himself.'" This is talking about something bad that happened durring the war.
In the second passage, it says, "Her village needed every able-bodied person to help defend against the Manchu." This person is obvisouly in a position of defense and how this girl is going to protect her village as her brother. Usually when protecting something, it's in a fight. Also, she said she "flinched" when she cut her first chunk of hair off, meaning it was causing her distress and wasn't easy.
