Question

Quizplus · Accepted Answer

All of the options listed involve goods or services that are non-excludable and non-rivalrous, meaning they are available to all members of the public and one person's use of the good does not diminish others' ability to use it. Space exploration benefits society as a whole by advancing scientific knowledge, a levee provides flood protection to the surrounding community, and national defense protects the entire nation. Therefore, they all qualify as public goods.
