What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? exists x_14: W(x_14) <-> Q_14(x_14). forall x_14: Q_14(x_14) -> R_6(x_14). forall x_14: W(x_14) -> Q(x_14). forall x_14: Q(x_14) -> W(x_14).
forall x_14: W(x_14) <-> Q(x_14). forall x_14: Q(x_14) <-> W(x_14). exists x_14: W(x_14) -> Q_14(x_14). exists x_14: Q_14(x_14) -> W(x_14).
