In writing and language, what best describes the relationship between a claim and evidence?

• A. Evidence is data used to support the claim.
• B. A claim is a statement or thesis; evidence is data used to support the claim.
• C. A claim is an opinion; evidence is data.
• D. Evidence and claim are interchangeable.

Answer: (B)

The main idea is that a claim is the statement or thesis a writer is trying to prove, and evidence is data used to support that claim. A claim is the central point you’re arguing, something that could be debated, while the evidence provides facts, examples, statistics, or expert opinions that back up that point and make it convincing. When you line these up, the claim stands up better because readers see a clear reason backed by concrete support.

For example, if you claim that school start times should be later, you’d back it up with evidence like research on teen sleep patterns, surveys from students and parents, and results from districts that shifted start times.

Why the other ideas aren’t as good: one description only defines evidence without clarifying what the claim is, leaving the relationship incomplete; another suggests a claim is merely an opinion, which isn’t always true since a claim can be a thesis supported by data; and saying evidence and claim are interchangeable would ignore the need for backing and make the argument meaningless.
