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_1: T(z_1) -> R(z_1). forall z_1: W_2(z_1) -> R(z_1). W_4(h) or w. forall z_1: W_2(z_1) or T(z_1). forall z_1: W_4(z_1) -> ~R(z_1).
forall z_1: R(z_1) can be inferred via the universal disjunction elimination rule.
