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: Q_10(x_10) -> S_3(x_10). forall x_10: S_3(x_10) -> P(x_10). exists x_10: U_4(x_10). forall x_10: U_4(x_10) -> S_3(x_10).
exists x_10: S_3(x_10) can be inferred via the existential modus ponens rule. forall x_10: Q_10(x_10) -> P(x_10) can be inferred via the universal transitivity rule. forall x_10: U_4(x_10) -> P(x_10) can be inferred via the universal transitivity rule.
