Quizplus · Accepted Answer

A non-excludable good or service is one that is difficult or impossible to exclude people from using, regardless of whether they have paid for it or not. A rival good or service is one that can only be used by one person at a time, and consumption by one person reduces the quantity available to others. Of the options listed, the only example that fits both criteria is a free concert with limited seating in a public park. Anyone can attend the concert, and once the seating is full, others will be unable to attend. This makes it non-excludable and rival in consumption.
