Consider the following premises. There is at least one x_6 for which x_6 will not drive a car. For all x_6, if x_6 were a carpenter, then x_6 is playing squash. For all x_6, if x_6 drives a car, then x_6 is a carpenter. For all x_6, x_6 will drive a car or x_6 will not play squash. Can we infer the following from them? For all x_6, x_6 will play squash.
 From the fact that for all x_6, if x_6 drives a car, then x_6 is a carpenter, and that for all x_6, if x_6 were a carpenter, then x_6 is playing squash we can infer that for all x_6, if x_6 drives a car, then x_6 is playing squash. From the fact that for all x_6, x_6 will drive a car or x_6 will not play squash we can infer that for all x_6, if x_6 plays squash, then x_6 is driving a car. From the fact that for all x_6, if x_6 drives a car, then x_6 is playing squash, and that for all x_6, if x_6 plays squash, then x_6 is driving a car we can infer that for all x_6, x_6 will drive a car if and only if x_6 will play squash. Finally, from the fact that for all x_6, x_6 will drive a car if and only if x_6 will play squash, and that there is at least one x_6 for which x_6 will not drive a car we can infer that there is at least one x_6 for which x_6 will not play squash, which contradicts that For all x_6, x_6 will play squash. Therefore, the answer is no.
