What is an expository essay?

An expository essay is defined as a type of writing that aims to explain, inform, or clarify a specific topic or concept. This essay format is characterized by its use of facts, examples, and logical reasoning to present information clearly and concisely. The primary goal is to provide the reader with a comprehensive understanding of the subject matter, often without the author's personal opinions or emotional responses.

In this context, the choice that highlights the descriptive and factual nature of an expository essay accurately encompasses its purpose. Such essays are structured to guide the reader through information systematically, often addressing questions related to 'how' or 'why' something occurs, thus enhancing the reader’s knowledge on the topic without the influence of personal anecdotes or fictional elements.
