What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all x_6, if x_6 were poor, then x_6 is an artist. For all x_6, x_6 will work or x_6 is not an artist. There is at least one x_6 for which x_6 is poor or x_6 will sleep. For all x_6, if x_6 sleeps, then x_6 is working.
