Paste the library rules into your request. Then you can look for a line behind each claim.

The rules you paste are your material. A claim is one thing the answer says is true. To trace a claim, look for the line it came from. We say the claim hops back to that line.

Two lines from the material. Two claims in the answer.
Step 1 of 4
  1. Two lines from the material. Two claims in the answer.
  2. Claim A hops back to line 3.
  3. Line 3 agrees. The hop holds.
  4. Claim B hops to line 4. The answer says 5 rupees. The line says 2.

Read the rules below. Check each claim against them.

The rule

Work from material you supply. Make every claim hop back to a sentence in it. A claim with no sentence behind it stays unchecked. Do not use it until you check it somewhere else.

The request: "Can I keep a book longer? What if I return one late?" The rules are the six lines in the lab.

  • Three claims hop to a line, and the line agrees.
  • One claim hops to line 4. It says five rupees. The line says two.
  • One claim, about losing membership, hops nowhere. The rules never say it. It stays unchecked.

Never paste private details into a request. That means names, addresses, passwords and phone numbers. Not sure? Ask a trusted adult first.

Watch out!

A calm answer, one that sounds sure, is not a checked answer. A matching line shows the claim follows your page.
