Consider the following premises. There is at least one x_12 for which x_12 will listen to a song if and only if x_12 is a janitor. For all x_12, x_12 will listen to a song or x_12 will not make tea. For all x_12, if x_12 were an office clerk, then x_12 is making tea. Can we infer the following from them? For all x_12, the fact that x_12 were an office clerk does not imply that x_12 is a janitor.
That contradicts the premises. Therefore the answer is no.
