In the setup, you are presented with four actual cards in front of you, two where you can see a number, and two where you can see a color. This is verifiable with your senses. You are then told two statements about these cards and asked to verify the second statement. As OP of this thread pointed out, the card with 5 must be checked, because it's possible that it has an even number on its reverse side. I originally misinterpreted the OP as saying that both (1) and (2) must be verified. You can see the two sibling branches that explore both of these in much more depth and back and forth.
