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: U_1(z_3) and Q(z_3). forall z_3: R(z_3) or Q_3(z_3). exists z_3: ~R(z_3).
exists z_3: Q_3(z_3) can be inferred via the existential disjunctive syllogism rule. forall z_3: U_1(z_3) can be inferred via the universal simplification rule. forall z_3: Q(z_3) can be inferred via the universal simplification rule.
