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 y_3: P_1(y_3) -> S(y_3). forall y_3: S(y_3) -> Q(y_3). exists y_3: P_1(y_3) or ~Q(y_3).
forall y_3: P_1(y_3) -> Q(y_3) can be inferred via the universal transitivity rule. exists y_3: Q(y_3) -> P_1(y_3) can be inferred via the existential rewriting rule.
