Which example BEST fits the characteristics of a private good?

Question

Quizplus · Accepted Answer

Private goods are rivalrous and excludable, which means that access can be restricted and consuming the good reduces its availability for others. A book purchased from Barnes and Noble is an example of a private good because it is rivalrous (only one person can read it at a time) and excludable (the store can restrict access to paying customers). The other options do not fit the characteristics of a private good - a seminar is not rivalrous or excludable, fire service in a small town is not excludable, and vaccinations are non-rivalrous (one person's vaccination does not reduce the availability of the vaccine for others).
