What is required in expository writing that makes it different from narrative writing?

Expository writing is fundamentally different from narrative writing in that it primarily aims to inform, explain, or clarify a topic rather than tell a story. A thesis statement is a central element in expository writing, as it expresses the main idea or argument that the writing will develop and support. This statement provides a clear framework for the content that follows, guiding the reader through the information being presented.

In contrast, narrative writing focuses on storytelling elements, such as character development and plot, which are not essential in expository pieces. While narratives may include persuasive techniques to engage the reader, these techniques are not a requirement for effective expository writing. Therefore, the presence of a thesis statement is what distinctly characterizes expository writing.
