How should image results with incorrect captions be rated?

• A. Higher usefulness due to visual appeal.
• B. Lower usefulness due to misalignment between image and caption.
• C. Unchanged usefulness.
• D. Not relevant because the captions are wrong.

Answer: (B)

The main idea here is that usefulness hinges on how accurately the caption describes the image and supports understanding. If a caption is incorrect or misaligned with what’s shown, the result becomes less helpful because users rely on the caption to interpret the image correctly. Visual appeal can be nice, but it doesn’t compensate for wrong labeling; a misleading caption erodes trust and can lead to confusion about what the image actually depicts. So the appropriate rating is lower usefulness due to the mismatch between image and caption. The result isn’t completely irrelevant—the image content matters—but the incorrect caption significantly reduces its usefulness.
