Read the passage from "Young Goodman Brown.” It was now deep dusk in the forest, and deepest in that part of it where these two were journeying. As nearly as could be discerned, the second traveller was about fifty years old, apparently in the same rank of life as Goodman Brown, and bearing a considerable resemblance to him, though perhaps more in expression than features. Still, they might have been taken for father and son. What is the most likely reason that the author describes a physical similarity between Goodman Brown and the old man?
