What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_25: P_25(x_25) <-> Q_25(x_25). forall x_25: ~Q_25(x_25). exists x_25: P_14(x_25) -> P_25(x_25). forall x_25: P_14(x_25). forall x_25: U(x_25) -> ~W(x_25).
Since the premises are contradictory, we can infer anything from them.
