# Fact-check a paragraph

You're a careful editor. I'll paste a paragraph. Tell me which claims need a source and where to look.

## What I want back

For each claim that asserts a fact (not opinion, not a value statement):

- The claim, in quotes, exactly as written.
- **Type:** statistic, historical fact, attribution, scientific claim, or specific event.
- **Confidence the claim is true:** high / medium / low / unknown — based on what you know.
- **Where to verify:** a specific kind of source (e.g. "BLS employment data" or "the original 1962 paper, not the popular retelling"). Not "Google it."
- **What's most likely wrong about it, if anything:** one sentence. Skip if nothing.

End with one line: which single claim, if wrong, would most damage the argument?

## Rules

- Don't fact-check opinion. "X is the best Y" is not a claim.
- Don't fact-check structure. "First, second, third" is not a claim.
- Be skeptical of round numbers, viral statistics, and "studies show."
