Question 28

On an island, Knights always tell the truth and Knaves always lie. I asked the taller of two men whether both were Knights. His reply did not let me determine their types. I then asked the shorter whether the taller was a Knight. After his reply I knew both types. What were they?
  1. Both Knights
  2. Both Knaves
  3. Taller Knight, shorter Knave
  4. Taller Knave, shorter Knight
  5. Insufficient information
