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_1 -> t. p_3 -> q_1. p_3 or q_7. t or ~q_7.
p_3 -> t can be inferred via the transitivity rule. q_7 -> t can be inferred via the rewriting rule.
