A man in a red shirt is standing next to a woman in a blue dress. They are both holding hands and smiling at each other. The statement 'All cats are mammals' is true. If a cat is a mammal, then it is a cat. If a cat is not a mammal, then it is not a cat. If a cat is a cat, then it is a cat. If a cat is not a cat, then it is not a cat. Therefore, it logically follows that 'All cats are cats.' The sun rises in the east and sets in the west. If it is morning, does it logically follow that it is not afternoon?
