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_10: U_2(x_10). exists x_10: U_2(x_10) -> Q(x_10). forall x_10: P_3(x_10). forall x_10: P_3(x_10) -> R(x_10).
forall x_10: R(x_10) can be inferred via the universal modus ponens rule. exists x_10: Q(x_10) can be inferred via the existential modus ponens rule. forall x_10: U_2(x_10) and P_3(x_10) can be inferred via the universal conjunction rule. forall x_10: P_3(x_10) and U_2(x_10) can be inferred via the universal conjunction rule.
