What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: forall x_14: Q_14(x_14). forall x_14: W(x_14) -> ~Q_14(x_14). exists x_14: P_12(x_14) or Q_12(x_14). forall x_14: P_12(x_14) -> W(x_14). forall x_14: Q_12(x_14) -> W(x_14).
Since the premises are contradictory, we can infer anything from them.
