Find the true and the false statements.

1. Either 2 and 3 are both false or 2 and 4 are both true.
2. Either 1 is false and 3 is true or 3 is false and 4 is true.
3. If and only if 2 is false, then either 1 or 4 is true.
4. Either 1 and 2 are both false or 3 and 4 are both true.

(In reply to Boolean by Charlie)

I came to the conclusion that 1 is True and 2, 3, and 4 are false.

The statement condition, If and only if, does not create a contradiction by being false, but permits 1 or 3 to be true even if 2 is false.
