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_12: Q_12(x_12). p -> ~P_12(a_11). forall x_12: P_12(x_12).
forall x_12: Q_12(x_12) and P_12(x_12) can be inferred via the universal conjunction rule. forall x_12: P_12(x_12) and Q_12(x_12) can be inferred via the universal conjunction rule.
