What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all x_8, x_8 is rich if and only if x_8 will work. There is at least one x_8 for which x_8 will work or x_8 is a bartender. For all x_8, x_8 is not rich.
For all x_8, if x_8 were rich, then x_8 is working. For all x_8, if x_8 works, then x_8 is rich. For all x_8, x_8 will not work.
