Fact-check a piece of writing
Pulls out every checkable claim, sorts them by how much rides on them, and tells you what to verify and where. It does not pretend to know what it cannot.

Prompt
Go through the text below and help me fact-check it.
Step 1. List every factual claim: statistics, dates, quotes, named events, cause-and-effect statements, and claims about what a study or a person said. Skip opinions and predictions, but list them separately so I can see what is opinion presented as fact.
Step 2. For each claim, give:
- The claim, quoted.
- Type: number, quote, historical fact, scientific claim, or attribution.
- Your assessment: likely accurate, likely inaccurate, misleading, or cannot tell.
- Why: what you know that supports or contradicts it. Be specific about what is wrong, such as an outdated figure, a correlation presented as a cause, a quote that is commonly misattributed, or missing context.
- How to verify it: the kind of primary source that would settle it, such as an official statistics agency, the original study, a court record, or the full speech.
Step 3. Rank the claims by how much the piece depends on them. Which three, if wrong, would undermine its argument?
Rules:
- Your knowledge has a cutoff date and can be wrong. Say "cannot tell" when you are not confident; that is a useful answer.
- Never invent a source, a link, or a citation. Describe what kind of source to look for instead.
- Do not judge the conclusion of the piece. Only check its facts.
