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_6 -> q_6. s_3 or ~w. q_6 -> s_3. p_6 or w.
p_6 -> s_3 can be inferred via the transitivity rule. w -> s_3 can be inferred via the rewriting rule.
