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: t or ~q_12. w_4 or q_2. t or ~q_2. w_4 -> q_12.
q_12 -> t can be inferred via the rewriting rule. q_2 -> t can be inferred via the rewriting rule.
