Consider the following premises. There is at least one y_3 for which if y_3 reads a book, then y_3 is a police officer. For all y_3, if y_3 takes a plane, then y_3 is reading a book. Can we infer the following from them? If we can, name the inference rule being used: For all y_3, the fact that y_3 takes a plane does not imply that y_3 is a police officer.
That contradicts the premises. Therefore the answer is no.
