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: T(z_3). forall z_3: Q(z_3) and R(z_3). forall z_3: Q_1(z_3).
forall z_3: Q(z_3) can be inferred via the universal simplification rule. forall z_3: R(z_3) can be inferred via the universal simplification rule. forall z_3: T(z_3) and Q_1(z_3) can be inferred via the universal conjunction rule. forall z_3: Q_1(z_3) and T(z_3) can be inferred via the universal conjunction rule.
