Consider the following premises. For all x_12, x_12 is not happy. For all x_12, x_12 will listen to a song. For all x_12, if x_12 goes running, then x_12 is playing tennis. For all x_12, x_12 will read a book if and only if x_12 is happy. For all x_12, x_12 will read a book or x_12 will go running. Can we infer the following from them? For all x_12, x_12 will play tennis and x_12 will listen to a song.
 From the fact that for all x_12, x_12 will read a book if and only if x_12 is happy, and that for all x_12, x_12 is not happy we can infer that for all x_12, x_12 will not read a book. From the fact that for all x_12, x_12 will read a book or x_12 will go running, and that for all x_12, x_12 will not read a book we can infer that for all x_12, x_12 will go running. From the fact that for all x_12, if x_12 goes running, then x_12 is playing tennis, and that for all x_12, x_12 will go running we can infer that for all x_12, x_12 will play tennis. Finally, from the fact that for all x_12, x_12 will play tennis, and that for all x_12, x_12 will listen to a song we can infer that for all x_12, x_12 will play tennis and x_12 will listen to a song. Therefore, the answer is yes.
