Consider the following premises. For all z, if z were excited, then z is a soldier. There is at least one z for which if z were a soldier, then z is excited. For all z, if z were excited, then z is an astronaut. For all z, z is not an astronaut. Can we infer the following from them? For all z, z is a soldier.
 From the fact that for all z, if z were excited, then z is an astronaut, and that for all z, z is not an astronaut we can infer that for all z, z is not excited. From the fact that there is at least one z for which if z were a soldier, then z is excited, and that for all z, if z were excited, then z is a soldier we can infer that there is at least one z for which z is a soldier if and only if z is excited. Finally, from the fact that there is at least one z for which z is a soldier if and only if z is excited, and that for all z, z is not excited we can infer that there is at least one z for which z is not a soldier, which contradicts that For all z, z is a soldier. Therefore, the answer is no.
