Consider the following premises. For all x_6, x_6 will drink water or x_6 will play squash. For all x_6, if x_6 plays squash, then x_6 is working. For all x_6, x_6 will not drink water or x_6 is a police officer. For all x_6, if x_6 were a police officer, then x_6 is working. For all x_6, if x_6 works, then x_6 is driving a car. Can we infer the following from them? For all x_6, x_6 will drive a car.
 From the fact that for all x_6, x_6 will drink water or x_6 will play squash, and that for all x_6, x_6 will not drink water or x_6 is a police officer we can infer that for all x_6, x_6 will play squash or x_6 is a police officer. From the fact that for all x_6, if x_6 plays squash, then x_6 is working, that for all x_6, if x_6 were a police officer, then x_6 is working, and that for all x_6, x_6 will play squash or x_6 is a police officer we can infer that for all x_6, x_6 will work. Finally, from the fact that for all x_6, if x_6 works, then x_6 is driving a car, and that for all x_6, x_6 will work we can infer that for all x_6, x_6 will drive a car. Therefore, the answer is yes.
