A baseball hits a glove and the glove pushes on the ball.
A boy pushes on a door and the door swings open.
A soccer player kicks a ball and then another soccer player kicks the same ball.
A cat rubs up against a tree and the tree pushes against the cat.
A student pushes another student standing in a line, and that student falls into the next student.

The action-reaction pairs according to Newton's Third Law of Motion are:
1. **A girl leans against a wall and the wall pushes on the girl.** ✔️
- Action: The girl exerts a force on the wall.
- Reaction: The wall exerts an equal and opposite force on the girl.
2. **A baseball hits a glove and the glove pushes on the ball.** ✔️
- Action: The baseball exerts a force on the glove.
- Reaction: The glove exerts an equal and opposite force on the baseball.
3. **A boy pushes on a door and the door swings open.** ✖️
- This scenario does not clearly describe a direct action-reaction pair. While the boy exerts a force on the door, without specifying the reaction, it cannot be identified as a direct action-reaction pair.
4. **A soccer player kicks a ball and then another soccer player kicks the same ball.** ✖️
- This scenario involves two separate actions and does not form a direct action-reaction pair. The first soccer player kicking the ball is one action, and the second soccer player's kick is another independent action.
5. **A cat rubs up against a tree and the tree pushes against the cat.** ✔️
- Action: The cat exerts a force on the tree.
- Reaction: The tree exerts an equal and opposite force on the cat.
6. **A student pushes another student standing in a line, and that student falls into the next student.** ✖️
- This scenario describes a chain of events and does not detail a direct action-reaction pair. While the push is an action, the reaction of the second student falling into the next does not represent a clear action-reaction pair between the first student and the second student.
In conclusion, the valid action/reaction pairs from the list are the first, second, and fifth options.
1. **A girl leans against a wall and the wall pushes on the girl.** ✔️
- Action: The girl exerts a force on the wall.
- Reaction: The wall exerts an equal and opposite force on the girl.
2. **A baseball hits a glove and the glove pushes on the ball.** ✔️
- Action: The baseball exerts a force on the glove.
- Reaction: The glove exerts an equal and opposite force on the baseball.
3. **A boy pushes on a door and the door swings open.** ✖️
- This scenario does not clearly describe a direct action-reaction pair. While the boy exerts a force on the door, without specifying the reaction, it cannot be identified as a direct action-reaction pair.
4. **A soccer player kicks a ball and then another soccer player kicks the same ball.** ✖️
- This scenario involves two separate actions and does not form a direct action-reaction pair. The first soccer player kicking the ball is one action, and the second soccer player's kick is another independent action.
5. **A cat rubs up against a tree and the tree pushes against the cat.** ✔️
- Action: The cat exerts a force on the tree.
- Reaction: The tree exerts an equal and opposite force on the cat.
6. **A student pushes another student standing in a line, and that student falls into the next student.** ✖️
- This scenario describes a chain of events and does not detail a direct action-reaction pair. While the push is an action, the reaction of the second student falling into the next does not represent a clear action-reaction pair between the first student and the second student.
In conclusion, the valid action/reaction pairs from the list are the first, second, and fifth options.
