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_10 -> s. p_10 -> r_2. p_10. r_2 -> r_10.
r_2 can be inferred via the modus ponens rule. p_10 -> r_10 can be inferred via the transitivity rule. r_2 -> s can be inferred via the transitivity rule.
