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_10 -> u. p_10. u -> q_1. q_1 -> q.
u can be inferred via the modus ponens rule. p_10 -> q_1 can be inferred via the transitivity rule. u -> q can be inferred via the transitivity rule.
