Read the excerpt from "The Storyteller." "Were there any sheep in the park?” demanded Cyril. "No;” said the bachelor, "there were no sheep.” "Why weren’t there any sheep?” came the inevitable question arising out of that answer. The aunt permitted herself a smile, which might almost have been described as a grin. "There were no sheep in the park,” said the bachelor, "because the Prince’s mother had once had a dream that her son would either be killed by a sheep or else by a clock falling on him. For that reason the Prince never kept a sheep in his park or a clock in his palace.” Which statement best explains the situational irony in the passage?
