Correct answer: C — Vic

• Test each person as the culprit and count how many statements would then be true. We need exactly

3.

• If Vic did it: 3 statements are true. This matches.
• If Max did it: 1 statement is true. This does not match.
• If Gus did it: 2 statements are true. This does not match.
• If Quin did it: 2 statements are true. This does not match.
• Only Vic gives exactly 3 true statements.
• Why the other options are wrong:
• A (Quin): If Quin did it, the number of true statements would be 2, not 3.
• B (Gus): If Gus did it, the number of true statements would be 2, not 3.
• D (Max): If Max did it, the number of true statements would be 1, not 3.

Make a small table: culprits down the side, statements across the top, true or false in each cell.
