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_10, if x_10 climbs a mountain, then x_10 is making tea. For all x_10, if x_10 makes tea, then x_10 is sleeping. There is at least one x_10 for which if x_10 sleeps, then x_10 is excited. For all x_10, x_10 will climb a mountain or x_10 will not go running.
For all x_10, if x_10 climbs a mountain, then x_10 is sleeping can be inferred via the universal transitivity rule. There is at least one x_10 for which if x_10 makes tea, then x_10 is excited can be inferred via the existential transitivity rule. For all x_10, if x_10 goes running, then x_10 is climbing a mountain can be inferred via the universal rewriting rule.
