Select the answer choice that correctly describes George’s responses in the following:

Jerry: Is Elaine in the apartment?
George: Yes.
Jerry: Is that true?
George: No.
  1. If George’s second answer is true, his first answer is true.
  2. If George’s first answer is false, his second answer is true.
  3. Elaine must have left the apartment after George’s first response.
  4. If George’s first answer is false, his second answer is false.
Explanation
Answer: B - If George’s first answer is false, his second answer is true. If Elaine is not in the apartment, and George falsely answered that Elaine is in the apartment, then George’s second answer is true. Answer A is incorrect because George’s responses cannot both be true. Answer C is not correct because it adds facts that are not a part of the exchange between Jerry and George. Answer D is incorrect because George’s responses cannot both be false.
