Which of the following is NOT one of the three primary functions of exterior doors?

1. Means of entry and exit

2. Ventilation

3. Security

4. Fire resistance if they connect to a garage

The correct answer is: Ventilation

The selection of ventilation as not being one of the three primary functions of exterior doors is accurate because, while doors can facilitate ventilation when open or incorporate features like screens, their main objectives are centered around providing a means of entry and exit, ensuring security, and offering fire resistance, particularly if they are connected to areas such as garages. Exterior doors primarily serve to offer access to and from a building while also functioning as barriers to protect against outside threats and elements. The security function ensures that unauthorized access is prevented, while fire resistance is crucial for minimizing the spread of fire from a garage to the home, making it vital in terms of safety. Ventilation, on the other hand, is a secondary feature and not a primary function of exterior doors.
