Consider the following premises. There is at least one x_15 for which x_15 will listen to a song if and only if x_15 is an office clerk. For all x_15, if x_15 listens to a song, then x_15 is poor. For all x_15, x_15 is an office clerk if and only if x_15 is poor. Can we infer the following from them? For all x_15, the fact that x_15 listens to a song does not imply that x_15 is an office clerk.
That contradicts the premises. Therefore the answer is no.
