Consider the following premises. For all x_10, if x_10 were a janitor, then x_10 is a musician. There is at least one x_10 for which x_10 is an office clerk if and only if x_10 is a musician. For all x_10, if x_10 were an office clerk, then x_10 is listening to a song. Can we infer the following from them? For all x_10, the fact that x_10 were a janitor does not imply that x_10 is listening to a song.
That contradicts the premises. Therefore the answer is no.
