Consider the following premises. For all x_12, x_12 will not drive a car. There is at least one x_12 for which x_12 will drive a car or x_12 will read a book. For all x_12, x_12 is an astronaut. For all x_12, if x_12 were an astronaut, then x_12 is a writer. Can we infer the following from them? If we can, name the inference rule being used: For all x_12, x_12 is not a writer.
That contradicts the premises. Therefore the answer is no.
