Buying new clothes so that your friends will stop making fun of your old clothes a positive reinforcement or negative reinforcement?

Yeah u should that's the right thing

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. 

D, because civic virtue is basically doing what’s morally good.
