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: s_3 -> p_1. p_1 -> p. p -> s_3.
s_3 -> p can be inferred via the transitivity rule. p_1 -> s_3 can be inferred via the transitivity rule. p -> p_1 can be inferred via the transitivity rule.
