  1. All doctors are professionals. Some professionals are athletes. Which conclusion MUST be true?

    Answer: None of the above must be true

    The 'some professionals' who are athletes may or may not include any doctors. No specific conclusion about doctors and athletes must be true.

  2. If it rains, the picnic is cancelled. The picnic was NOT cancelled. What can you conclude?

    Answer: It did not rain

    Modus tollens: If P then Q; not-Q; therefore not-P. If rain implies cancelled, and not-cancelled, then it did not rain.

  3. No mammals are cold-blooded. All snakes are cold-blooded. Which statement must be true?

    Answer: No snakes are mammals

    No mammals are cold-blooded, and all snakes are cold-blooded, so snakes and mammals share no members.

  4. In a race: Alex finished before Beth. Beth finished before Carlos. Dana finished after Carlos. Who finished last?

    Answer: Dana

    Order: Alex, Beth, Carlos, Dana. Dana finished after Carlos, making Dana last.

  5. Every Friday, Sam goes to the gym. Sam did not go to the gym today. What can be concluded?

    Answer: It is not Friday

    Contrapositive: if Sam did not go to the gym, it cannot be Friday.

  6. Three mislabeled boxes contain apples, oranges, and a mix. The 'Mixed' box is opened and reveals only apples. What does the 'Oranges' box contain?

    Answer: Mixed

    All labels are wrong. 'Mixed' has apples. 'Oranges' cannot have oranges (wrong label) so it has mixed. 'Apples' has oranges.
