What is one possible way a city might use zoning laws

To restrict businesses that make residents less healthy

The correct answer is the following: A city might restrict the type of businesses that exists in certain areas, through the use of zoning laws. A zoning law is a type of written regulation or ordinance, that defines how property, in specific geographic zones, should be used. For example, a city's government uses zoning laws to establish which zones can be used for residential or business purposes, and establishes, through the law, the type of businesses that can be established in specific areas of the city.
