What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: There is at least one x_10 for which if x_10 drinks water, then x_10 is not working. For all x_10, x_10 will drink water. For all x_10, x_10 will go running. For all x_10, x_10 will work.
Since the premises are contradictory, we can infer anything from them.
