Which of the following is NOT a public good?

Question

Quizplus · Accepted Answer

Public goods are non-excludable and non-rivalrous, meaning that they are available to all individuals and one individual's use of the good does not diminish its availability for others. National defense, flood control projects, and environmental protection are all examples of public goods. Shirts at a clothing store, however, are a private good that is both excludable and rivalrous, as they are only available to those who have purchased them and one person's use of a shirt means that it cannot be used by someone else at the same time.
