Consider the following premises. For all x_5, if x_5 were a janitor, then x_5 is an artist. For all x_5, if x_5 were a police officer, then x_5 is a janitor. For all x_5, x_5 is a police officer or x_5 will not play a game. Can we infer the following from them? If we can, name the inference rule being used: For all x_5, if x_5 were a janitor, then x_5 is an artist.
That is one of the premises. Therefore, the answer is yes.
