Let P be the set of people we're interested in (not necessarily all people), Parent(p) mean p is a parent, and ParentOf(p1, p2) mean p1 is p2's parent. Consider the following statement: βx β P, βy β P, Parent(x) β ParentOf(x, y) If you were attempting to prove this statement via the challenge method, how would the "game" proceed? (An "adversary" is an opponent.) Group of answer choices If I can choose an x so that my adversary cannot choose a y that makes the statement false, then the statement is true. Otherwise, it's false. If I can choose an x and a y that make the statement true, then the statement is true. Otherwise, it's false. If my adversary cannot choose an x and a y that makes the statement false, then the statement is true. Otherwise, it's false. If no matter what choice of x my adversary makes, I can choose a y that makes the statement true, then the statement is true. Otherwise, it's false. None of these is correctly describes the process, but there is a correct process. None of these is correctly describes the process, and there is no correct process to prove this statement via the challenge method.
