Paradoxical Phrase
Riddle: Jasmine was the worst student in her class. One day, her instructor, Mr. Collins, gave her a chance to stay in her class and not be expelled. He said, "Give me a statement. If the statement is true, you will not be expelled from the class. And if the statement is false, you will be expelled from the class. So, what do you say?". What should Jasmine say to stay in her class?
Answer: Jasmine should say, "I will be expelled from the class,". If we suppose that the statement is true, then Jasmine would not be expelled from the class. But then, it makes the statement false. And if we suppose that the statement is false, then Jasmine would be expelled from the class. But then, it makes the statement true. This phrase creates a paradox, as it cannot be true AND false at the same time.
