Self-referential multiple-choice test

Seth sez. "This is a multiple-choice standardized test where (almost) all the questions are about the test itself. Since it's possible to get 20 out of 20, the test is actually a logic puzzle. And it's fun."

1. The first question whose answer is B is question: (A) 1 (B) 2 (C) 3 (D) 4 (E) 5

17. The answer to question 6 is: (A) C (B) D (C) E (D) none of the above (E) all of the above

19. The answer to this question is: (A) A (B) B (C) C (D) D (E) E
