Final answer:
An unreliable narrator challenges readers to question the truth of the story, leading to a deeper engagement with the text.
Explanation:
Unreliable narrator is a literary device where the narrator's credibility is questionable, leading readers to question the truth of the story. This can make readers determine the truth for themselves by critically analyzing the narrator's account and identifying inconsistencies or biases.
For example, in Edgar Allan Poe's The Tell-Tale Heart, the narrator's mental instability creates doubt about the accuracy of events, altering the reader's perspective and creating tension as readers try to piece together the truth amidst the narrator's distortions.
