Consider the following premises. For all x_13, if x_13 were an electrician, then x_13 is working. For all x_13, if x_13 sleeps, then x_13 is working. There is at least one x_13 for which x_13 is fast and x_13 is a poet. For all x_13, x_13 will sleep or x_13 is an electrician. Can we infer the following from them? If we can, name the inference rule being used: For all x_13, x_13 will sleep or x_13 is an electrician.
That is one of the premises. Therefore, the answer is yes.
