From huimu----to test your IQ

Three gods A, B, and C are called, in some order, True, False, and
Random. True always speaks truly, False always speaks falsely, but whether Random speaks truly or falsely is a completely random matter. Your task is to determine the identities of A, B, and C by asking three yes-no questions; each question must be put to exactly one god. The gods understand English, but will answer all questions
in their own language, in which the words for “yes” and “no” are “da” and “ja,” in some order. You do not know which word means which.
