Final answer:
Attaching movie screens to a utilitarian building would not enhance its primary purpose, as utilitarian buildings are designed for functionality and to serve specific, practical purposes.
Step-by-step explanation:
The question asks which of the following changes to a utilitarian building would not enhance its purpose. Among the options provided, attaching movie screens on the side of each building to entertain people as they drive would not be practical for a utilitarian building. Utilitarian buildings are designed for functionality to serve specific purposes related to their use. For example, options like building a handicap accessible ramp leading to the front door or having telephones in the lobby to call residents serve practical functions that align with the Americans with Disabilities Act (ADA) and contribute to the building's accessibility and inclusiveness. Adding additional windows to each apartment building could enhance the living experience by providing more natural light, but attaching movie screens would be an entertainment feature that does not align with the primary utilitarian purpose of the building.
