Given Fitch's proof showing that the judge’s statement leads to a contradiction if 'surprise' is defined as the prisoner’s inability to deduce the execution day, what is the correct resolution of the paradox when considering that the prisoner’s deductions themselves create a contradiction, implying the judge’s statement is true only if the prisoner cannot logically deduce the day without self-defeat?	The judge's statement is true, and the prisoner's deductions are self-defeating.	5	logic
