Which of the following is an example of a common good? Cookies that are commonly consumed. Fish in the ocean. Lighthouses. Public schools.

Lighthouses serve as a perfect example of a common good because they provide navigation assistance to all ships, enhancing maritime safety without exclusion. Whether a luxury yacht or a cargo ship, every vessel benefits from their guiding light, illustrating the essence of shared resources that can be enjoyed by everyone. Public schools also represent a vital common good, as they provide essential education to children in the community regardless of their background. By supporting the collective growth of society through education, public schools help cultivate informed citizens who contribute positively to the community, making knowledge accessible to all.
