Which of the following best defines chapter?

• A. A branch of a society or group
• B. A section of a book or a written work
• C. A stage in a person's life
• D. A graph

Answer: (B)

A chapter is a major division in a book or written work, used to organize content into a sequence. It usually covers a specific part of the story or argument and helps readers navigate the text, often appearing with a number or title. This makes it the best definition because it directly describes how books are structured. There are other uses of the word, such as a local branch of an organization or a stage in someone’s life, but those senses are less central to how the word is most commonly understood in a reading context. A graph has no relation to how books are divided, so it doesn’t fit.
