Consider the following premises. For all x_15, x_15 is a sailor or x_15 will go running. There is at least one x_15 for which x_15 will listen to a song or x_15 is a police officer. For all x_15, x_15 is not a sailor or x_15 is bored. For all x_15, x_15 will not listen to a song. For all x_15, x_15 will not go running. Can we infer the following from them? There is at least one x_15 for which x_15 is bored and x_15 is a police officer.
 From the fact that for all x_15, x_15 is a sailor or x_15 will go running, and that for all x_15, x_15 is not a sailor or x_15 is bored we can infer that for all x_15, x_15 will go running or x_15 is bored. From the fact that there is at least one x_15 for which x_15 will listen to a song or x_15 is a police officer, and that for all x_15, x_15 will not listen to a song we can infer that there is at least one x_15 for which x_15 is a police officer. From the fact that for all x_15, x_15 will go running or x_15 is bored, and that for all x_15, x_15 will not go running we can infer that for all x_15, x_15 is bored. Finally, from the fact that for all x_15, x_15 is bored, and that there is at least one x_15 for which x_15 is a police officer we can infer that there is at least one x_15 for which x_15 is bored and x_15 is a police officer. Therefore, the answer is yes.
