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: For all x_11, if x_11 cooks, then x_11 is a taxi driver. There is at least one x_11 for which if x_11 goes running, then x_11 is cooking. For all x_11, if x_11 were a taxi driver, then x_11 is running. For all x_11, x_11 will go running or x_11 is a server. For all x_11, x_11 will not cook.
There is at least one x_11 for which x_11 will not go running can be inferred via the existential modus tollens rule. For all x_11, if x_11 cooks, then x_11 is running can be inferred via the universal transitivity rule. There is at least one x_11 for which if x_11 goes running, then x_11 is a taxi driver can be inferred via the existential transitivity rule. There is at least one x_11 for which if x_11 were a taxi driver, then x_11 is cooking can be inferred via the existential transitivity rule.
