Question

Quizplus · Accepted Answer

A light house is a public good as it benefits everyone in the vicinity (such as ships navigating in the sea) and it is non-excludable, meaning that it is impossible to prevent people from benefiting from it even if they do not contribute to its provision. Options A, B, and D are not public goods as they are rivalrous and excludable - meaning that one person's use of the good prevents someone else from using it and it is possible to prevent some people from accessing it.
