For each of the following problems, imagine that you are on a strange and unusual island, the natives of which are either Knights or Knaves. Knights may only tell the truth, whereas Knaves may only tell falsehoods. (Consequently, no one can be both a knight and a knave.) Each native wears medieval armor, and upon the breastplate of their armor, they have a single letter emblazoned (e.g., A, B, C, ....). Thus, the natives can be identified by the letter emblazoned on their breastplate. After C, D, and E leave, F, G, and H arrive F: All of us are knaves. G: Exactly one of us is aknave. What is F? What is G? What is H?
