Consider the following premises. There is at least one z for which z is not a cashier or z will read a book. For all z, z will not listen to a song or z is poor. For all z, z is a cashier or z will listen to a song. Can we infer the following from them? If we can, name the inference rule being used: For all z, neither z will read a book nor z is poor.
That contradicts the premises. Therefore the answer is no.
