A LITTLE DOUBT GOES A LONG WAY

Sounds true.
But is it?

Four claims. Only one is true.
Match evidence to the three false claims. Leave the true one alone.

  1. Find a card that breaks a claim. One example that agrees with it is not enough.
  2. Pick a card and a claim, in either order. Your second choice tests them. Each correct match uses its card once.
  3. Three cards go unused. Your third mistake ends the attempt.

A QUICK FIELD GUIDE

Find the fishy claims.

Three claims have a hole in them. One holds up.

Use only the information given for this puzzle. Choose a claim and a card in either order. The second choice tests them immediately.

For “If X, then Y,” the card must meet X and break Y. A correct match uses the card. A rejected pair costs one mistake only, even if you try it again. Three different mistakes end the attempt.
