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 y_2: U(y_2). forall y_2: P_5(y_2).
forall y_2: U(y_2) and P_5(y_2) can be inferred via the universal conjunction rule. forall y_2: P_5(y_2) and U(y_2) can be inferred via the universal conjunction rule.
