The choice that best describes the forces at work on the girl, her friend, and the seesaw is:
When the girl pushes down, her friend is pulled up. When the girl is pushed down, her friend is pushed up.
This accurately reflects the mechanics of a seesaw, where the downward force exerted by one person causes the other person to rise, and vice versa. When the girl pushes down on her side of the seesaw, it creates an upward force on her friend, causing her friend's side to rise.
