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_6, if x_6 goes running, then x_6 is making tea. For all x_6, if x_6 drives a car, then x_6 is running. For all x_6, if x_6 cooks, then x_6 is driving a car. There is at least one x_6 for which if x_6 makes tea, then x_6 is cooking.
For all x_6, if x_6 drives a car, then x_6 is making tea can be inferred via the universal transitivity rule. For all x_6, if x_6 cooks, then x_6 is running can be inferred via the universal transitivity rule. There is at least one x_6 for which if x_6 makes tea, then x_6 is driving a car can be inferred via the existential transitivity rule. There is at least one x_6 for which if x_6 goes running, then x_6 is cooking can be inferred via the existential transitivity rule.
