Consider the following premises. For all x_3, if x_3 sleeps, then x_3 is driving a car. For all x_3, if x_3 were a politician, then x_3 is sleeping. There is at least one x_3 for which if x_3 drives a car, then x_3 is a politician. Can we infer the following from them? For all x_3, the fact that x_3 sleeps does not imply that x_3 is driving a car.
That contradicts the premises. Therefore the answer is no.
