What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_7: P(x_7) <-> S_7(x_7). s <-> q. ~q. s <-> S_7(a_7).
s -> q. s -> S_7(a_7). q -> s. S_7(a_7) -> s. ~s. forall x_7: P(x_7) -> S_7(x_7). forall x_7: S_7(x_7) -> P(x_7).
