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: q_13. p_17. p_17 -> p. s or ~q_13.
p can be inferred via the modus ponens rule. q_13 and p_17 can be inferred via the conjunction rule. p_17 and q_13 can be inferred via the conjunction rule. q_13 -> s can be inferred via the rewriting rule.
