true
false

Explanation:

In a classroom setting, especially in a lab environment where gas valves are present (like in chemistry labs), safety protocols require that gas valves should only be operated with the teacher's permission, regardless of the presence of flames or sparks. This is to ensure proper safety procedures are followed and to prevent any potential hazards that might not be immediately obvious.
