Consider the following premises. For all x_13, if x_13 were curious, then x_13 is sleeping. There is at least one x_13 for which if x_13 sleeps, then x_13 is running. For all x_13, if x_13 were a soldier, then x_13 is not running. For all x_13, x_13 is curious or x_13 is a nurse. For all x_13, if x_13 were a nurse, then x_13 is sleeping. Can we infer the following from them? There is at least one x_13 for which x_13 is not a soldier.
 From the fact that for all x_13, if x_13 were curious, then x_13 is sleeping, that for all x_13, if x_13 were a nurse, then x_13 is sleeping, and that for all x_13, x_13 is curious or x_13 is a nurse we can infer that for all x_13, x_13 will sleep. From the fact that there is at least one x_13 for which if x_13 sleeps, then x_13 is running, and that for all x_13, x_13 will sleep we can infer that there is at least one x_13 for which x_13 will go running. Finally, from the fact that for all x_13, if x_13 were a soldier, then x_13 is not running, and that there is at least one x_13 for which x_13 will go running we can infer that there is at least one x_13 for which x_13 is not a soldier. Therefore, the answer is yes.
