Consider the following premises. For all x_12, if x_12 were a soldier, then x_12 is sad. There is at least one x_12 for which x_12 is a soldier. For all x_12, if x_12 were sad, then x_12 is sleeping. Can we infer the following from them? For all x_12, neither x_12 will sleep nor x_12 will drink water.
 From the fact that for all x_12, if x_12 were a soldier, then x_12 is sad, and that there is at least one x_12 for which x_12 is a soldier we can infer that there is at least one x_12 for which x_12 is sad. From the fact that for all x_12, if x_12 were sad, then x_12 is sleeping, and that there is at least one x_12 for which x_12 is sad we can infer that there is at least one x_12 for which x_12 will sleep. Finally, from the fact that there is at least one x_12 for which x_12 will sleep we can infer that there is at least one x_12 for which x_12 will sleep or x_12 will drink water, which contradicts that For all x_12, neither x_12 will sleep nor x_12 will drink water. Therefore, the answer is no.
