Consider the following premises. For all x_11, x_11 is not a taxi driver or x_11 will read a book. For all x_11, x_11 is a taxi driver or x_11 is a musician. There is at least one x_11 for which x_11 is not a musician. Can we infer the following from them? If we can, name the inference rule being used: For all x_11, neither x_11 will read a book nor x_11 is a police officer.
That contradicts the premises. Therefore the answer is no.
