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_16: W_3(x_16) -> Q_1(x_16). forall x_16: ~Q_1(x_16). forall x_16: Q_16(x_16) -> W_3(x_16). forall x_16: P_16(x_16) -> W_3(x_16). exists x_16: P_16(x_16) or Q_16(x_16).
Since the premises are contradictory, we can infer anything from them.
