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