What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: forall z: T_3(z) <-> S(z). forall z: T_1(z) or S_2(z). forall z: ~T_3(z). forall z: S_2(z) -> S(z). forall z: S(z) -> S_2(z). forall z: ~T_1(z) or Q(z).
forall z: S_2(z) or Q(z) can be inferred via the universal resolution rule. forall z: S_2(z) <-> S(z) can be inferred via the universal biconditional introduction rule. forall z: S(z) <-> S_2(z) can be inferred via the universal biconditional introduction rule. forall z: T_3(z) -> S(z) can be inferred via the universal biconditional elimination rule. forall z: S(z) -> T_3(z) can be inferred via the universal biconditional elimination rule. forall z: ~S(z) can be inferred via the universal biconditional elimination rule.
