Explanation:

Newton's Third Law states that for every action, there is an equal and opposite reaction. When the bird exerts a force on the air (action), the air exerts an equal and opposite force on the bird (reaction). This is what allows the bird to fly. So the student's claim that only the bird exerts a force on the air is incorrect.

The claim is incorrect; the air exerts an equal and opposite force on the bird.
