Claims and Evidence All successful arguments contain a claim and evidence. The claim presents a position on an issue or topic. For a claim to be debatable, people should be able to hold differing opinions about it. If your claim is something that is generally agreed upon or accepted as fact, then there is no reason to try to convince people. Evidence is information that supports the claim. 3.
