What is a chapter in the context of a book?

A chapter serves as a main division of a book, organizing the text into manageable sections that usually focus on a specific aspect of the story or theme. Chapters help to structure the narrative, making it easier for readers to follow the plot and understand character development, settings, and individual events. Each chapter often presents a unique segment of the overall storyline, allowing for a more coherent and engaging reading experience.

The other choices do not accurately define a chapter. A brief summary of the book encapsulates the overall content, rather than dividing it into sections. A type of character suggests a specific role within a narrative, which is unrelated to the organizational structure of the text. A conclusion of the story refers to the closing parts of a narrative, which is separate from the ongoing divisions that chapters provide throughout the book.
