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 were rich, then x_10 is drinking water. If Michael were fast, then it is raining. If it rains, then Charles is rich.
If Michael were fast, then Charles is rich can be inferred via the transitivity rule.
