Consider the following premises. For all x_12, x_12 is a server and x_12 is an electrician. For all x_12, if x_12 were an artist, then x_12 is playing squash. There is at least one x_12 for which x_12 is an artist. Can we infer the following from them? There is at least one x_12 for which x_12 will play squash and x_12 is a server.
 From the fact that for all x_12, x_12 is a server and x_12 is an electrician we can infer that for all x_12, x_12 is a server. From the fact that for all x_12, if x_12 were an artist, then x_12 is playing squash, and that there is at least one x_12 for which x_12 is an artist we can infer that there is at least one x_12 for which x_12 will play squash. Finally, from the fact that there is at least one x_12 for which x_12 will play squash, and that for all x_12, x_12 is a server we can infer that there is at least one x_12 for which x_12 will play squash and x_12 is a server. Therefore, the answer is yes.
