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_3: Q_4(z_3) or ~T_4(z_3). forall z_3: Q(z_3) -> R_3(z_3). exists z_3: R_3(z_3) -> T_4(z_3).
exists z_3: Q(z_3) -> T_4(z_3) can be inferred via the existential transitivity rule. forall z_3: T_4(z_3) -> Q_4(z_3) can be inferred via the universal rewriting rule.
