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_4 -> r_1. s_4 and q_10. s_4 -> r_4.
s_4 -> r_1 can be inferred via the transitivity rule. s_4 can be inferred via the simplification rule. q_10 can be inferred via the simplification rule.
