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: p_2 -> T(g). forall x_20: P_20(x_20) or Q_20(x_20). forall x_20: ~P_20(x_20). forall x_20: T(x_20) -> ~Q_20(x_20).
forall x_20: Q_20(x_20) can be inferred via the universal disjunctive syllogism rule.
