Consider the following premises. For all x_7, x_7 will play tennis. For all x_7, x_7 is a bartender or x_7 will not play tennis. There is at least one x_7 for which if x_7 were a bartender, then x_7 is a soldier. Can we infer the following from them? For all x_7, x_7 is not a soldier.
 From the fact that for all x_7, x_7 is a bartender or x_7 will not play tennis we can infer that for all x_7, if x_7 plays tennis, then x_7 is a bartender. From the fact that for all x_7, if x_7 plays tennis, then x_7 is a bartender, and that there is at least one x_7 for which if x_7 were a bartender, then x_7 is a soldier we can infer that there is at least one x_7 for which if x_7 plays tennis, then x_7 is a soldier. Finally, from the fact that there is at least one x_7 for which if x_7 plays tennis, then x_7 is a soldier, and that for all x_7, x_7 will play tennis we can infer that there is at least one x_7 for which x_7 is a soldier, which contradicts that For all x_7, x_7 is not a soldier. Therefore, the answer is no.
