Emergency roof hatches on a bus may be locked in which position for fresh air?

Explanation:
Partially open. Keeping the emergency roof hatch in a partially open position provides fresh air flow into the cabin while staying secured enough to prevent rain, debris, or accidental opening during travel. It balances ventilation with safety: enough opening to ventilate, but not so wide that it creates weather or safety hazards. Fully open would invite weather and potential hazards, while fully closed would stop the air exchange altogether.
