Consider the following premises. There is at least one z for which if z were rich, then z is a mechanic. For all z, z is a mechanic if and only if z will read a book. For all z, if z reads a book, then z is rich. Can we infer the following from them? If we can, name the inference rule being used: For all z, the fact that z reads a book does not imply that z is rich.
That contradicts the premises. Therefore the answer is no.
