Consider the following premises. For all x_14, x_14 is an astronaut. For all x_14, if x_14 were an astronaut, then x_14 is a musician. For all x_14, if x_14 makes tea, then x_14 is a server. For all x_14, x_14 is not a server. There is at least one x_14 for which x_14 will make tea or x_14 is happy. Can we infer the following from them? There is at least one x_14 for which x_14 is happy and x_14 is a musician.
 From the fact that for all x_14, if x_14 makes tea, then x_14 is a server, and that for all x_14, x_14 is not a server we can infer that for all x_14, x_14 will not make tea. From the fact that for all x_14, if x_14 were an astronaut, then x_14 is a musician, and that for all x_14, x_14 is an astronaut we can infer that for all x_14, x_14 is a musician. From the fact that there is at least one x_14 for which x_14 will make tea or x_14 is happy, and that for all x_14, x_14 will not make tea we can infer that there is at least one x_14 for which x_14 is happy. Finally, from the fact that there is at least one x_14 for which x_14 is happy, and that for all x_14, x_14 is a musician we can infer that there is at least one x_14 for which x_14 is happy and x_14 is a musician. Therefore, the answer is yes.
