Answer:
A public good that a state government might provide is low-rent apartments. Public goods are goods or services that are non-excludable and non-rivalrous, meaning they are available to everyone and one person's use does not diminish the availability for others. In this case, low-rent apartments provided by the state government can be considered a public good as they are available to everyone and one person's occupancy does not prevent others from being able to rent them. Grocery stores, movie theaters, and amusement parks are not public goods as they are excludable and rivalrous, meaning access can be restricted and one person's use reduces availability for others.
