I gave my students this multiple choice question: The piping plover is a bird that builds its nest on sand dunes along the Atlantic Ocean. Which of these actions most likely damages the nests of the piping plover?

Only one answer is correct among these 4 choices:
- people fishing from a boat
- children playing in the ocean waves
- children digging holes along the sand dunes
- people walking on a sidewalk along the sand dunes

Could you tell me which one is correct?
