Consider the following premises. For all x_3, if x_3 were a server, then x_3 is playing squash. There is at least one x_3 for which if x_3 reads a book, then x_3 is a server. For all x_3, if x_3 plays squash, then x_3 is reading a book. Can we infer the following from them? If we can, name the inference rule being used: For all x_3, the fact that x_3 reads a book does not imply that x_3 is playing squash.
That contradicts the premises. Therefore the answer is no.
