Question

one example of regulating zoning is
limiting the number of fast - food restaurants that can be built near a residential area.
making sure trash pickup, street cleaning, and snow - plowing services are in place.
raising revenue for a new city hall to replace an existing structure that is in disrepair.
staffing local public swimming pools and beaches with qualified lifeguards.

Zoning regulations control land - use. Limiting fast - food restaurants near residential areas is a land - use control. Other options are about services or revenue, not zoning.

limiting the number of fast - food restaurants that can be built near a residential area.
