SINCE THE FIRST TWO QUANTIFIERS ARE UNIVERSAL AND THE LAST QUANTIFIER IS EXISTENTIAL, FARLEY CHOOSESX AND Y, AFTER WHICH, YOU CHOOSE Z

65. Since the first two quantifiers are universal and the last quantifier is existential, Farley chooses

x and y, after which, you choose z. Whatever values Farley chooses, you can choose z to be

one less than the minimum of x and y; thus making

(z < x) ∧ (z < y)

true. Since you can always win the game, the quantified propositional function is true.
