Consider the following premises. For all x_22, x_22 will go running or x_22 will read a book. For all x_22, if x_22 reads a book, then x_22 is working. There is at least one x_22 for which x_22 will not go running. For all x_22, if x_22 works, then x_22 is poor. For all x_22, x_22 is poor if and only if x_22 will play tennis. Can we infer the following from them? There is at least one x_22 for which x_22 will play tennis.
 From the fact that for all x_22, x_22 will go running or x_22 will read a book, and that there is at least one x_22 for which x_22 will not go running we can infer that there is at least one x_22 for which x_22 will read a book. From the fact that for all x_22, if x_22 reads a book, then x_22 is working, and that for all x_22, if x_22 works, then x_22 is poor we can infer that for all x_22, if x_22 reads a book, then x_22 is poor. From the fact that for all x_22, x_22 is poor if and only if x_22 will play tennis we can infer that for all x_22, if x_22 were poor, then x_22 is playing tennis. From the fact that for all x_22, if x_22 reads a book, then x_22 is poor, and that there is at least one x_22 for which x_22 will read a book we can infer that there is at least one x_22 for which x_22 is poor. Finally, from the fact that for all x_22, if x_22 were poor, then x_22 is playing tennis, and that there is at least one x_22 for which x_22 is poor we can infer that there is at least one x_22 for which x_22 will play tennis. Therefore, the answer is yes.
