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

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

Answer: (A)

This question tests how the Object or Ground labeling decides whether something is part of the surface or a separate item in the scene. A streetlight is fixed to the ground and is considered a fixture of the surface rather than a standalone object you would lift or move. In this labeling scheme, that association with the ground means it should be labeled as ground. Labeling it as an object would imply it’s a discrete item separate from the surface, which isn’t how this task groups elements. Hazard isn’t the right category for general labeling unless the item is specifically a risk, and Unknown is used only when the category can’t be determined. So the streetlight is labeled as ground.
