Free-riding refers to the behavior of individuals who benefit from a public good without contributing to its support or provision. In the given scenarios, examples of free-riding can be found in options b, d, and e.
In option b, Bob listens to the radio station without donating, assuming others will donate enough to keep the station on the air. This is an example of free-riding.
In option d, Jim avoids doing the extra work in a group project and expects other group members to pick up the slack. This is also an example of free-riding.
