Consider the following premises. There is at least one x_5 for which x_5 is a nurse or x_5 is excited. For all x_5, x_5 will not take a plane. For all x_5, x_5 is not a nurse or x_5 will take a plane. For all x_5, x_5 is not excited or x_5 is a lawyer. Can we infer the following from them? There is at least one x_5 for which x_5 is a lawyer.
 From the fact that there is at least one x_5 for which x_5 is a nurse or x_5 is excited, and that for all x_5, x_5 is not a nurse or x_5 will take a plane we can infer that there is at least one x_5 for which x_5 is excited or x_5 will take a plane. From the fact that there is at least one x_5 for which x_5 is excited or x_5 will take a plane, and that for all x_5, x_5 is not excited or x_5 is a lawyer we can infer that there is at least one x_5 for which x_5 will take a plane or x_5 is a lawyer. Finally, from the fact that there is at least one x_5 for which x_5 will take a plane or x_5 is a lawyer, and that for all x_5, x_5 will not take a plane we can infer that there is at least one x_5 for which x_5 is a lawyer. Therefore, the answer is yes.
