Consider the following premises. There is at least one x_4 for which x_4 is a politician. For all x_4, if x_4 were excited, then x_4 is a server. For all x_4, x_4 will play tennis or x_4 is excited. For all x_4, if x_4 plays tennis, then x_4 is a server. Can we infer the following from them? Some politicians are servers.
 From the fact that for all x_4, if x_4 plays tennis, then x_4 is a server, that for all x_4, if x_4 were excited, then x_4 is a server, and that for all x_4, x_4 will play tennis or x_4 is excited we can infer that for all x_4, x_4 is a server. Finally, from the fact that there is at least one x_4 for which x_4 is a politician, and that for all x_4, x_4 is a server we can infer that some politicians are servers. Therefore, the answer is yes.
