Consider the following premises. Susan is rich or Karen is playing a game. For all x_13, if x_13 were an electrician, then x_13 is playing a game. Susan is not rich or Thomas is sad. For all x_13, x_13 is not an electrician. For all x_13, if x_13 plays a game, then x_13 is an electrician. Can we infer the following from them? If we can, name the inference rule being used: Susan is sleeping.
We cannot infer that from the premises. Therefore the answer is no.
