Consider the following premises. For all x_15, x_15 is a cashier if and only if x_15 will cook. There is at least one x_15 for which x_15 will drive a car or x_15 is a cashier. For all x_15, x_15 will not cook. For all x_15, x_15 will not drive a car or x_15 will go running. For all x_15, if x_15 were a soldier, then x_15 is not running. Can we infer the following from them? There is at least one x_15 for which x_15 is not a soldier.
 From the fact that there is at least one x_15 for which x_15 will drive a car or x_15 is a cashier, and that for all x_15, x_15 will not drive a car or x_15 will go running we can infer that there is at least one x_15 for which x_15 is a cashier or x_15 will go running. From the fact that for all x_15, x_15 is a cashier if and only if x_15 will cook, and that for all x_15, x_15 will not cook we can infer that for all x_15, x_15 is not a cashier. From the fact that there is at least one x_15 for which x_15 is a cashier or x_15 will go running, and that for all x_15, x_15 is not a cashier we can infer that there is at least one x_15 for which x_15 will go running. Finally, from the fact that for all x_15, if x_15 were a soldier, then x_15 is not running, and that there is at least one x_15 for which x_15 will go running we can infer that there is at least one x_15 for which x_15 is not a soldier. Therefore, the answer is yes.
