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: Q_4(x). forall x: R_1(x).
forall x: Q_4(x) and R_1(x) can be inferred via the universal conjunction rule. forall x: R_1(x) and Q_4(x) can be inferred via the universal conjunction rule.
