Consider the following premises. For all x_12, if x_12 makes tea, then x_12 is a musician. For all x_12, x_12 is a nurse and x_12 will work. There is at least one x_12 for which x_12 will make tea. Can we infer the following from them? Some musicians are nurses.
 From the fact that for all x_12, x_12 is a nurse and x_12 will work we can infer that for all x_12, x_12 is a nurse. From the fact that for all x_12, if x_12 makes tea, then x_12 is a musician, and that there is at least one x_12 for which x_12 will make tea we can infer that there is at least one x_12 for which x_12 is a musician. Finally, from the fact that there is at least one x_12 for which x_12 is a musician, and that for all x_12, x_12 is a nurse we can infer that some musicians are nurses. Therefore, the answer is yes.
