Consider the following premises. For all x_6, x_6 is excited. For all x_6, x_6 will play squash or x_6 is a server. For all x_6, if x_6 plays squash, then x_6 is not excited. For all x_6, if x_6 were a server, then x_6 is cooking. Can we infer the following from them? For all x_6, x_6 will cook.
 From the fact that for all x_6, if x_6 plays squash, then x_6 is not excited, and that for all x_6, x_6 is excited we can infer that for all x_6, x_6 will not play squash. From the fact that for all x_6, x_6 will play squash or x_6 is a server, and that for all x_6, x_6 will not play squash we can infer that for all x_6, x_6 is a server. Finally, from the fact that for all x_6, if x_6 were a server, then x_6 is cooking, and that for all x_6, x_6 is a server we can infer that for all x_6, x_6 will cook. Therefore, the answer is yes.
