Consider the following premises. For all x_8, x_8 is not curious. For all x_8, x_8 will drink water or x_8 is a doctor. For all x_8, x_8 will drive a car. For all x_8, if x_8 drinks water, then x_8 is curious. Can we infer the following from them? John is not a doctor.
 From the fact that for all x_8, if x_8 drinks water, then x_8 is curious, and that for all x_8, x_8 is not curious we can infer that for all x_8, x_8 will not drink water. Finally, from the fact that for all x_8, x_8 will drink water or x_8 is a doctor, and that for all x_8, x_8 will not drink water we can infer that for all x_8, x_8 is a doctor, which contradicts that John is not a doctor. Therefore, the answer is no.
