Which statement best describes ventilation?

• A. The deliberate supply of outdoor air and removal of indoor air to maintain air quality
• B. The process of heating the space
• C. The process of painting the walls
• D. The process of lighting the stage

Answer: (A)

Ventilation is the deliberate supply of outdoor air and removal of indoor air to maintain air quality. In a theatre backstage setting, this process dilutes and removes fumes from paints, solvents, and smoke effects, helps control humidity, and keeps the air breathable for cast and crew. It can be achieved with mechanical systems like fans and ducts or with natural methods such as open doors or vents, and it is distinct from heating, painting, or lighting, which are separate functions.
