Consider the following premises. For all x_10, x_10 will sleep. For all x_10, if x_10 drives a car, then x_10 is not sleeping. For all x_10, if x_10 were poor, then x_10 is curious. There is at least one x_10 for which if x_10 were curious, then x_10 is driving a car. Can we infer the following from them? There is at least one x_10 for which x_10 is not poor.
 From the fact that for all x_10, if x_10 drives a car, then x_10 is not sleeping, and that for all x_10, x_10 will sleep we can infer that for all x_10, x_10 will not drive a car. From the fact that there is at least one x_10 for which if x_10 were curious, then x_10 is driving a car, and that for all x_10, x_10 will not drive a car we can infer that there is at least one x_10 for which x_10 is not curious. Finally, from the fact that for all x_10, if x_10 were poor, then x_10 is curious, and that there is at least one x_10 for which x_10 is not curious we can infer that there is at least one x_10 for which x_10 is not poor. Therefore, the answer is yes.
