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: It is not late. If Jennifer were a police officer, then it is overcast. It is late if and only if it is not cloudy. Jennifer is a police officer if and only if it is cloudy. It is not overcast.
Since the premises are contradictory, we can infer anything from them.
