What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all x_14, if x_14 were fast, then x_14 is a mechanic. For all x_14, x_14 is rich. For all x_14, if x_14 were a musician, then x_14 is a mechanic. There is at least one x_14 for which x_14 is a musician or x_14 is fast. For all x_14, if x_14 were a mechanic, then x_14 is not rich.
Since the premises are contradictory, we can infer anything from them.
