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: p -> r_10. p_10 -> p. p_10 and s_2.
p_10 -> r_10 can be inferred via the transitivity rule. p_10 can be inferred via the simplification rule. s_2 can be inferred via the simplification rule.
