Text features like captions and diagrams support comprehension by doing what?

• A. They distract from main ideas
• B. They replace the need to read the text
• C. They only serve decoration
• D. They provide extra information, clarify text, and aid in locating key ideas

Answer: (D)

Text features like captions and diagrams help readers understand by providing extra information, clarifying what the text says, and guiding you to where key ideas are located. A caption explains what the image is showing and can define terms, while a diagram lays out steps, relationships, or processes in a visual sequence. This pairing of words and pictures helps you build a clearer mental picture of the content, making it easier to grasp main ideas and remember details. They also act as signposts on the page, pointing you toward important information and evidence you might need to answer questions. They’re not distractions, decorations, or replacements for reading—they deepen understanding by linking visuals to the written text.
