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_1. q -> p_2. p_10 -> r_1. p_2 -> p_10.
~p_10 can be inferred via the modus tollens rule. p_2 -> r_1 can be inferred via the transitivity rule.
