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: u_4 -> t. t -> q_10. u_4. q_10 -> p.
t can be inferred via the modus ponens rule. u_4 -> q_10 can be inferred via the transitivity rule. t -> p can be inferred via the transitivity rule.
