Consider the following premises. For all x_10, if x_10 drives a car, then x_10 is curious. For all x_10, if x_10 were curious, then x_10 is a bartender. For all x_10, x_10 is an artist or x_10 will drive a car. For all x_10, if x_10 were an artist, then x_10 is curious. There is at least one x_10 for which x_10 is not a bartender or x_10 is a police officer. Can we infer the following from them? If we can, name the inference rule being used: For all x_10, neither x_10 is excited nor x_10 is a police officer.
That contradicts the premises. Therefore the answer is no.
