Consider the following premises. For all x_9, x_9 is a soldier if and only if x_9 will take a plane. For all x_9, if x_9 takes a plane, then x_9 is not a police officer. Michael is a police officer. Can we infer the following from them? There is at least one x_9 for which x_9 is not a soldier.
 From the fact that Michael is a police officer we can infer that there is at least one x_9 for which x_9 is a police officer. From the fact that for all x_9, if x_9 takes a plane, then x_9 is not a police officer, and that there is at least one x_9 for which x_9 is a police officer we can infer that there is at least one x_9 for which x_9 will not take a plane. Finally, from the fact that for all x_9, x_9 is a soldier if and only if x_9 will take a plane, and that there is at least one x_9 for which x_9 will not take a plane we can infer that there is at least one x_9 for which x_9 is not a soldier. Therefore, the answer is yes.
