Consider the following premises. There is at least one y for which y will not listen to a song or y will take a plane. For all y, if y takes a plane, then y is a politician. For all y, y will listen to a song or y is a police officer. For all y, if y were a police officer, then y is a politician. For all y, y will drive a car. Can we infer the following from them? There is at least one y for which y will drive a car and y is a politician.
 From the fact that for all y, y will listen to a song or y is a police officer, and that there is at least one y for which y will not listen to a song or y will take a plane we can infer that there is at least one y for which y is a police officer or y will take a plane. From the fact that for all y, if y were a police officer, then y is a politician, that for all y, if y takes a plane, then y is a politician, and that there is at least one y for which y is a police officer or y will take a plane we can infer that there is at least one y for which y is a politician. Finally, from the fact that for all y, y will drive a car, and that there is at least one y for which y is a politician we can infer that there is at least one y for which y will drive a car and y is a politician. Therefore, the answer is yes.
