Consider the following premises. If Charles reads a book, then Thomas is fast. For all x_10, if x_10 were a cashier, then x_10 is reading a book. For all x_10, if x_10 reads a book, then x_10 is a cashier. Can we infer the following from them? The fact that Charles were a cashier does not imply that Thomas is fast.
That contradicts the premises. Therefore the answer is no.
