Match the chain of command in the european feudal system with its equivalent in japan. 1. monarch emperor 2. lords shogun 3. lesser lords samurai 4. knights daimyo

Monarch=Emperor: this is the political leader of the government.
Lords=Shogun: This is the only match left to make sense of this but the Shoguns were very powerful and were the military leaders. They are more like a general and would reign over large regions of Japan. 
Lesser Lords=Daimyo: this group were feudal leaders and often owned vast amounts of land in addition to having some political power
Knight=Samuari: this group are the warriors responsible for protecting the land and government. Typically they were assigned to a lord or daimyo.
