How does a caption or diagram support understanding of a photograph or chart in informational text?

• A. Captions explain what the image shows; diagrams illustrate relationships; both give essential context to the text.
• B. Captions are decorative; diagrams are optional.
• C. Images should be ignored when reading.
• D. Captions simply repeat the text.

Answer: (A)

The idea being tested is how captions and diagrams support understanding by connecting visuals to the written text and adding context. A caption explains what the image shows and can add details such as what’s happening, who or where it’s from, or why it matters. A diagram goes beyond a picture to show relationships, steps, or parts working together, making how the information fits together clearer. Together, captions and diagrams give essential context to the text, helping you grasp meaning more fully and remember it better. Why the other ideas don’t fit: captions aren’t just decorative, and diagrams aren’t optional—they enrich understanding. Images shouldn’t be ignored when reading, and captions aren’t merely a repetition of the text; they provide additional information that clarifies and connects to the written message.
