Glad to help. Without that rule, recursivity doesn't end. Prolog will successively shorten the list and will arrive at an empty list and no rule will tell it how to get the minimum out of that list, so it will fail. We have to provide the answer manually when the list gets to be 1-element long, because it's easy for us to know the answer at that point, without relying on recursivity.
