What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? exists x_14: ~Q_14(x_14). forall x_14: Q_14(x_14) -> U(x_14). forall x_14: U(x_14) <-> Q_14(x_14). forall x_14: U(x_14).
Since the premises are contradictory, we can infer anything from them.
