Consider the following premises. For all y_3, if y_3 were a server, then y_3 is bored. For all y_3, y_3 is sad. For all y_3, y_3 will work or y_3 will go running. For all y_3, if y_3 goes running, then y_3 is bored. For all y_3, y_3 will not work or y_3 is a server. Can we infer the following from them? For all y_3, y_3 is bored and y_3 is sad.
 From the fact that for all y_3, y_3 will work or y_3 will go running, and that for all y_3, y_3 will not work or y_3 is a server we can infer that for all y_3, y_3 will go running or y_3 is a server. From the fact that for all y_3, if y_3 goes running, then y_3 is bored, that for all y_3, if y_3 were a server, then y_3 is bored, and that for all y_3, y_3 will go running or y_3 is a server we can infer that for all y_3, y_3 is bored. Finally, from the fact that for all y_3, y_3 is bored, and that for all y_3, y_3 is sad we can infer that for all y_3, y_3 is bored and y_3 is sad. Therefore, the answer is yes.
