You hear the sound of an engine running from the garage next door. When you open the door, you see your neighbor lying on the floor. What is the first thing to do?
Explication
The English option texts diverge from the source editions: the accepted source response requires opening the garage doors wide, stopping the engine, and removing the casualty if possible, whereas merely unlocking the doors does not ventilate the space. Separately, current first-aid guidance calls trained rescuers and permits ventilation only from outside because an unprotected bystander must not enter carbon monoxide.
