"A Horseman in the Sky" is a short story that was written by Civil War ex soldier and survivor Ambrose Bierce and it was published in 1889. The story narrates the experiences and life of Carter Druse, a young man from Virginia who, despite his father´s opposition, decides to join the Union Army and fight against the Confederation in the Civil War. In essence, this story reveals not just the difficulties of this war, but also its devastating effects on the people and families who lived through it. At the hart of the story lies a particular experience, from which the title derives, in which a young soldier sees a man on a Confederate horse, standing on a ledge, and he shoots the horse because he does not feel morally prepared to kill the man. As this happens, another soldier is standing below the ledge and he sees as if the horse and man were flying through the sky and he is so shocked that when he returns he cannot explain the situation very well. In this particular excerpt of the story, when Carter has informed his father of his decision to leave, his father tries to disuade his son by giving him a piece of his mind on the matter, and especially, by trying to use guilt as a disuading technique. This can be better seen in the first few lines of the excerpt, so the correct answer would be A: "Well, go, sir, and whatever may occur do what you conceive to be your duty. Virginia, to which you are a traitor, must get on without you."
