Final answer:
Poe creates irony in 'The Tell-Tale Heart' through a contrast between expectation and reality, as well as unreliable narration.
Step-by-step explanation:
Poe creates irony in 'The Tell-Tale Heart' through various techniques. One way he does this is by creating a contrast between what is expected and what actually happens. For example, in the story, the narrator tries to convince the reader that he is not mad, but his actions and thoughts prove otherwise. This creates irony because the narrator's obsession with proving his sanity only serves to further demonstrate his insanity.
Another way Poe creates irony is through the unreliable narration of the story. The narrator's account of the events is distorted and biased, leading the reader to question the truth of his version of events. This creates irony because the reader is left to uncover the true nature of the narrator's actions and motivations.
