Consider the following premises. For all x, if x takes a plane, then x is a police officer. James is taking a plane. Can we infer the following from them? James is not a police officer.
 From the fact that for all x, if x takes a plane, then x is a police officer we can infer that if James takes a plane, then James is a police officer. Finally, from the fact that if James takes a plane, then James is a police officer, and that James is taking a plane we can infer that James is a police officer, which contradicts that James is not a police officer. Therefore, the answer is no.
