Break Down the Problem

2. Determine which text feature specifically relates to explaining images or graphics.

Relevant Concepts

• Caption: A brief explanation or description accompanying an image or graphic.

3. Heading: A heading organizes text content but does not typically relate to images or graphics.
4. Glossary: A glossary provides definitions and context for terms, but it's separate from images.
