Which of the following statements about gate decisions are true?

The key idea here is handling self-referential truth values. You have two statements about gate decisions, call their truth values t1 and t2. The four meta-statements translate to: - The statement “neither is true” is true exactly when both t1 and t2 are false. - The statement “both are true” is true exactly when t1 and t2 are both true. - The statement “only the first is true” is true exactly when t1 is true and t2 is false. - The statement “only the second is true” is true exactly when t1 is false and t2 is true. If both underlying statements are false (t1 and t2 are false), then the first meta-statement (neither is true) is true, and the others are false. That makes the option describing “neither is true” the only true option in this consistent scenario, which is why the correct choice matches that statement. If you try other truth-value patterns (one true, or both true), a different meta-statement becomes true, which under the problem’s setup would point to a different correct option. Since the given answer is the one stating neither is true, the intended interpretation is that both underlying statements are false, yielding a consistent solution where that first option is true.

The key idea here is handling self-referential truth values. You have two statements about gate decisions, call their truth values t1 and t2. The four meta-statements translate to:

  • The statement “neither is true” is true exactly when both t1 and t2 are false.

  • The statement “both are true” is true exactly when t1 and t2 are both true.

  • The statement “only the first is true” is true exactly when t1 is true and t2 is false.

  • The statement “only the second is true” is true exactly when t1 is false and t2 is true.

If both underlying statements are false (t1 and t2 are false), then the first meta-statement (neither is true) is true, and the others are false. That makes the option describing “neither is true” the only true option in this consistent scenario, which is why the correct choice matches that statement.
