Consider the following premises. For all x_7, if x_7 sleeps, then x_7 is not playing tennis. There is at least one x_7 for which if x_7 plays squash, then x_7 is sleeping. For all x_7, x_7 will play tennis and x_7 will read a book. Can we infer the following from them? For all x_7, x_7 will play squash.
 From the fact that for all x_7, x_7 will play tennis and x_7 will read a book we can infer that for all x_7, x_7 will play tennis. From the fact that for all x_7, if x_7 sleeps, then x_7 is not playing tennis, and that for all x_7, x_7 will play tennis we can infer that for all x_7, x_7 will not sleep. Finally, from the fact that there is at least one x_7 for which if x_7 plays squash, then x_7 is sleeping, and that for all x_7, x_7 will not sleep we can infer that there is at least one x_7 for which x_7 will not play squash, which contradicts that For all x_7, x_7 will play squash. Therefore, the answer is no.
