Quizplus · Accepted Answer

National defense is a classic example of a public good because it is non-excludable (meaning individuals cannot be excluded from its benefits) and non-rivalrous (meaning one person's consumption of national defense does not diminish another's consumption). Libraries can also be considered a public good, but timber is a private good (excludable and rivalrous), as its use by one person or entity reduces its availability for use by others.
