In the Object or Ground task, how should Person in crosswalk be labeled?

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

Answer: (A)

In the Object or Ground task, the key idea is to separate what sits on the surface from what stands above or apart from it. A person in a crosswalk is a discrete entity that occupies space above the road surface, so it should be labeled as an object. The ground label covers the road, crosswalk, and other surface areas themselves. The labels hazard or unknown aren’t used for this binary distinction when the region is clearly a person—unknown would be for uncertain regions, and hazard is a broader category not part of this specific task.
