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_16: U_4(x_16). P_3(a_3). forall x_16: Q_16(x_16).
exists x: P_3(x) can be inferred via the existential generalization rule. forall x_16: U_4(x_16) and Q_16(x_16) can be inferred via the universal conjunction rule. forall x_16: Q_16(x_16) and U_4(x_16) can be inferred via the universal conjunction rule.
