response: Well, so let me tell you some facts about it. There is an offense trying to advance down the field and a defense aiming to stop the defense
original_response: Oh really? It is kind of simple, you just need to watch it. First the ball starts with the offense, their goal is to get it into the endzone.
history: I don't really know the rules of American Football
knowledge: The offense, which is the team controlling the oval-shaped football, attempts to advance down the field by running with or passing the ball, while the defense, which is the team without control of the ball, aims to stop the offense's advance and aims to take control of the ball for themselves.
