The document discusses different types of irony used in Kate Chopin's short story "The Story of an Hour". It explains that Chopin uses literary, situational, and dramatic irony. As an example of literary irony, the main character Louise believes her husband is dead but he is actually still alive. This causes situational irony when Louise discovers he is alive and dies from the revelation. The story also uses dramatic irony, where the audience understands a situation that characters do not, such as other characters believing Louise died happily from her husband's return.
