Which passage utilizes metaphor to emphasize Montag's departure from his old life, a life in which he engaged with vapid company who were devoid of personality?
“He imagined thousands on thousands of faces peering into yards, into alleys, and into the sky, faces hid by curtains, pale, night-frightened faces, like grey animals peering from electric caves...”
“He floated on his back when the valise filled and sank; the river was mild and leisurely, going away from the people who ate shadows for breakfast and steam for lunch and vapours for supper. The river was very real...”

"You've been locked up here for years with a regular damned Tower of Babel. Snap out of it! The people in those books never lived. Come on now!"
