Which type of writing is used to explain or inform?

• A. Expository writing
• B. Narrative writing
• C. Descriptive writing
• D. Persuasive writing

Answer: (A)

Expository writing explains or informs. It aims to present facts, definitions, and explanations in a clear, logical order so readers can understand how something works, why it happens, or what something means. It often uses steps, processes, comparisons, or cause-and-effect relationships and relies on precise information rather than storytelling or arguing a point. For example, a science section that describes how photosynthesis works or a how-to guide that lists steps to complete a task are expository. Narrative writing tells a story with characters and events; descriptive writing focuses on sensory details; persuasive writing tries to convince the reader of a position.
