Consider the following premises. Richard is not happy. For all x_22, x_22 will drive a car if and only if x_22 will cook. Barbara is not cooking. For all x, x is a server if and only if x is happy. Can we infer the following from them? If we can, name the inference rule being used: If Richard were not a server, then Barbara is not driving a car.
We cannot infer that from the premises. Therefore the answer is no.
