Look back at the previous rules. The new rule with lead and silver seems to break one! This brings up an important part of the solubility rules: their order. The rules form a list so when they seem to contradict, the higher one takes precedent.

Americans often speak of their country as one of several large regions.  these regions are cultural units rather than governmental units --  formed by history and geography and shaped by the economics, literature and folkways that all the parts of a region share. what makes one region different from another? a region's multicultural heritage as well as distinct demographic characteristics like age and occupation make regions different and special. within several regions, language is used differently and there are strong dialects. there are also differences in outlook and attitude based on geography.
