Solution #51: Multiple Choice
E. Consider the choices. Contradictions between answers, such as between
C and D, eliminate A as a possibility. B is false because if it were correct,
then C would also be true. It follows that C is false because both A and B
are false. Similarly, it follows that D is false. Aha! E is true!
Of course, that result makes F false.
