Minor nit on question 53: It's Carta, not Charta.
Minor nit on question 53: It's Carta, not Charta.
MAJOR nit on question 59: Solving encrypted messages by checking letter frequencies is the stuff of puzzles in popular magazines and children's books. The Enigma cipher was '''much''' more difficult than that. The rotors advanced, completely changing the permutation, after every letter. Solving the Enigma cipher required the concentrated effort of the best minds of the British mathematics community. See "Alan Turing: The Enigma" by Andrew Hodges.

See "Alan Turing: The Enigma" by Andrew Hodges for a readable, but not ''too'' technical account, of the problem and the way it was attacked.
