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: R_11(a_10) <-> P_11(a_10). forall x_11: P_11(x_11) -> Q_11(x_11). forall x_11: Q_11(x_11) -> R_11(x_11).
R_11(a_10) -> P_11(a_10) can be inferred via the biconditional elimination rule. P_11(a_10) -> R_11(a_10) can be inferred via the biconditional elimination rule. forall x_11: P_11(x_11) -> R_11(x_11) can be inferred via the universal transitivity rule.
