What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_14: Q_4(x_14) <-> Q_14(x_14). forall x_14: Q_4(x_14) -> S(x_14). forall x_14: S(x_14) -> Q_4(x_14). p -> S(a_5). forall x_14: ~Q_14(x_14).
forall x_14: Q_4(x_14) <-> S(x_14). forall x_14: S(x_14) <-> Q_4(x_14). forall x_14: Q_4(x_14) -> Q_14(x_14). forall x_14: Q_14(x_14) -> Q_4(x_14). forall x_14: ~Q_4(x_14).
