In the Object or Ground task, how should Bicycle be labeled?

• A. Ground
• B. Unknown
• C. Object
• D. Hazard

Answer: (C)

In the Object or Ground task, you determine whether a region represents a distinct item (object) or part of the scene background (ground). A bicycle is a distinct, countable item in the scene, not just a background surface, so it should be labeled as an object. Labeling it as ground would mischaracterize the region as merely part of the surface, and unknown would be used only if you couldn’t tell, while hazard is for safety- or risk-related labeling, which isn’t implied here. So the correct labeling is Object.
