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_1 -> q_16. w_4 -> p. ~t_1 -> w_4. ~q_16.
~t_1 can be inferred via the modus tollens rule. ~t_1 -> p can be inferred via the transitivity rule.
