What type of passage is designed to inform and enlighten the reader?

The correct choice, expository, refers to a type of writing that aims to convey information and explanations to the reader. Expository passages are characterized by their straightforward style, focusing on delivering facts, definitions, and descriptions in a clear and logical manner. This type of writing often includes evidence and examples to support the information presented, allowing the reader to gain a deeper understanding of the topic.

Expository writing contrasts with persuasive passages, which are designed to convince the reader of a particular argument or viewpoint and may use emotional appeals. Narrative passages tell a story, focusing on plot, characters, and settings, rather than primarily informing the reader. Descriptive writing emphasizes vivid imagery and sensory details to create a strong impression or evoke a specific feeling but does not primarily aim to inform or explain. Therefore, expository writing is uniquely suited to inform and enlighten readers about various subjects.
