Which of the following is considered a feature of expository text?

Expository text is designed to inform, explain, or describe a particular topic or subject to the reader. It typically presents facts, ideas, and concepts in a straightforward manner, which is why the inclusion of headings and subheadings is a defining feature. These elements help to organize information clearly, guiding the reader through different sections of the text and highlighting key points and themes. This structural aspect is essential in expository writing, as it aids comprehension and retention of the material presented.

In contrast, elements like character analysis, dialogue, and plot development are primarily found in narrative or literary texts, focusing on storytelling rather than providing informative content. Narrative texts engage readers' emotions and imagination through character-driven plots and interactions, which are not the objectives of expository writing. Therefore, the presence of headings and subheadings stands out as a hallmark of expository text, facilitating clear communication of information.
