Final answer:
Edgar Allan Poe increases pacing and tension in 'The Tell-Tale Heart' through the use of short sentences, punctuation, and repetition, creating a fast-paced, suspenseful atmosphere.
Step-by-step explanation:
In "The Tell-Tale Heart" by Edgar Allan Poe, the pacing and tension are increased through the use of short sentences, punctuation, and repetition. Short sentences contribute to a feeling of urgency and breathlessness, as if events are happening rapidly. Exclamation points and italics are used to emphasize the narrator's extreme emotion and increasing insanity, heightening the reader's anxiety and engagement. The repetition of certain phrases and sounds, like the beating of the old man's heart, creates a rhythmic and suspenseful buildup to the climax of the story.
