Answer: The exposition of the story is presented in the lines; "There was once a Parsee living on an uninhabited island in the Red Sea, with a shiny hat, a knife, and a cooking-stove."
Step-by-step explanation: A narrative exposition is the introduction of a character's background, the environment, or past events that preceded the story. In this tale, the exposition of the story is at the beginning. You learn that a Parsee was living in an uninhabited island and that he had a knife and a cooking stove. This is important later on in the story, since that man bakes cakes, and puts crumbs from previous ones on the Rhino's skin, to then make him rub everywhere and have wrinkles on it.
