If you are looking for definitions of refutation, concession, and rebuttal, you can find those through searching online fairly easily. However, they are still tricky to use in a paper. One tip I have for you is that a concession is when you are admitting someone else has a point; they may not be totally correct, but you are acknowledging their viewpoint. If you choose refutation or rebuttal, you are mainly focused on arguing against another position.
You have listed the topic as Federalist Papers. Assuming that this is your subject, the opposing viewpoint belonged to the Anti-Federalists.
I am available for lessons if you need further help!
