Consider the following premises. For all x_5, if x_5 cooks, then x_5 is reading a book. For all x_5, if x_5 reads a book, then x_5 is driving a car. For all x_5, x_5 will cook or x_5 will play squash. For all x_5, x_5 will drive a car if and only if x_5 will play squash. Can we infer the following from them? There is at least one x_5 for which x_5 will not drive a car.
 From the fact that for all x_5, if x_5 cooks, then x_5 is reading a book, and that for all x_5, if x_5 reads a book, then x_5 is driving a car we can infer that for all x_5, if x_5 cooks, then x_5 is driving a car. From the fact that for all x_5, x_5 will drive a car if and only if x_5 will play squash we can infer that for all x_5, if x_5 plays squash, then x_5 is driving a car. Finally, from the fact that for all x_5, if x_5 cooks, then x_5 is driving a car, that for all x_5, if x_5 plays squash, then x_5 is driving a car, and that for all x_5, x_5 will cook or x_5 will play squash we can infer that for all x_5, x_5 will drive a car, which contradicts that There is at least one x_5 for which x_5 will not drive a car. Therefore, the answer is no.
