Consider the following premises. There is at least one z for which if z were fast, then z is driving a car. For all z, z is fast if and only if z will drink water. For all z, if z drives a car, then z is poor. Can we infer the following from them? If we can, name the inference rule being used: For all z, the fact that z drinks water does not imply that z is poor.
That contradicts the premises. Therefore the answer is no.
