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: If Sarah were an electrician, then Karen is cooking. If Michael were a police officer, then Sarah is an electrician. For all x_15, if x_15 cooks, then x_15 is a nurse. If it is overcast, then Michael is a police officer. If Karen were a nurse, then it is windy.
If Michael were a police officer, then Karen is cooking can be inferred via the transitivity rule. If it is overcast, then Sarah is an electrician can be inferred via the transitivity rule.
