What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_5: Q_5(x_5) -> P_5(x_5). forall x_5: ~Q_5(x_5). exists x_5: S_4(x_5) <-> P_5(x_5). forall x_5: P_5(x_5) -> Q_5(x_5).
forall x_5: ~P_5(x_5). forall x_5: Q_5(x_5) <-> P_5(x_5). forall x_5: P_5(x_5) <-> Q_5(x_5). exists x_5: S_4(x_5) -> P_5(x_5). exists x_5: P_5(x_5) -> S_4(x_5).
