Read this excerpt from "The World on Turtle's Back." One day, when the girl had become a woman, a man appeared. No one knows where this man came from. Perhaps he was sent from the Gods above. The girl was so filled with wonder to see this strange man, she lost her senses and fainted. The man yielded two very different arrows, and laid them across the body of the girl in opposite directions, then he disappeared.

Which statement best describes the significance of the arrows?
