Security screens protect openings leading outside such as which of the following?

• A. Doors
• B. Windows
• C. Vents, ducts, skylights
• D. Basements

Answer: (C)

The main idea is that security screens are used on openings that go directly to the outside and could be exploited for entry. Vents, ducts, and skylights fit this description because they are external openings that burglars can reach or manipulate, often without the same level of protection as doors or windows. Installing a security screen on these helps block access while still allowing airflow or light. Doors and windows are typical entry points and are usually protected with other hardware, and basements describe a location rather than a specific type of opening. Therefore, vents, ducts, and skylights are the openings most addressed by security screens.
