Consider the following premises. There is at least one x_10 for which x_10 is a soldier. For all x_10, x_10 will take a plane. For all x_10, if x_10 were a soldier, then x_10 is a server. Can we infer the following from them? For all x_10, x_10 is not a server.
 From the fact that there is at least one x_10 for which x_10 is a soldier, and that for all x_10, x_10 will take a plane we can infer that some soldiers will take a plane. From the fact that some soldiers will take a plane we can infer that there is at least one x_10 for which x_10 is a soldier. Finally, from the fact that for all x_10, if x_10 were a soldier, then x_10 is a server, and that there is at least one x_10 for which x_10 is a soldier we can infer that there is at least one x_10 for which x_10 is a server, which contradicts that For all x_10, x_10 is not a server. Therefore, the answer is no.
