Short,long

A fast paced story will have more short sentences, and a story with a slow pace will have more long sentences. This is because short sentences can create a sense of urgency and quick movement in the narrative, while long sentences can slow down the pace and provide more detail and description. By varying the length of sentences, a writer can effectively control the pacing of their story and create different moods and atmospheres for the reader.
