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_9: P_9(x_9) or ~Q_9(x_9). P_9(j) -> Q_9(j).
forall x_9: Q_9(x_9) -> P_9(x_9) can be inferred via the universal rewriting rule.
