Consider the following premises. For all x_11, x_11 is a musician or x_11 is an office clerk. There is at least one x_11 for which if x_11 were an office clerk, then x_11 is making tea. For all x_11, if x_11 were a musician, then x_11 is making tea. For all x_11, x_11 will not make tea or x_11 will play a game. Can we infer the following from them? If we can, name the inference rule being used: For all x_11, neither x_11 is a lawyer nor x_11 will play a game.
That contradicts the premises. Therefore the answer is no.
