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_1(z_1). forall z_1: T(z_1) or ~W(z_1). forall z_1: T(z_1) or ~T_1(z_1).
forall z_1: W(z_1) -> T(z_1) can be inferred via the universal rewriting rule. forall z_1: T_1(z_1) -> T(z_1) can be inferred via the universal rewriting rule.
