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_7: U_4(x_7) -> Q_7(x_7). forall x_7: U_4(x_7) and Q_5(x_7). forall x_7: ~Q_7(x_7).
Since the premises are contradictory, we can infer anything from them.
