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 x_7: P_7(x_7) -> S(x_7). forall x_7: P_7(x_7) and Q_7(x_7).
forall x_7: P_7(x_7) can be inferred via the universal simplification rule. forall x_7: Q_7(x_7) can be inferred via the universal simplification rule.
