The treaty of kanagawa
a. gave japan control over korea
c. opened two trading ports in japan to the americans
b. established peace between russia and japan
d. opened trading ports in china for the japanese

The answer is that it opened treaties with the Americans or letter c.  It is also called Perry Convention and it is the first treaty that Japan had with Westerners.  This happened when Commodore Mathew Perry sailed into Tokyo Bay and made demands for supplies for his war fleet by opening their ports.  He gave them time to think over.  After realizing they were no match for his warships, they signed a treaty with the United States which marked the end of their seclusion.

- "the past is made of multitudinous items ranging from anything that can be collected, recollected or assessed to originate in the past. as such, the past is a gallimaufry of particulars that may not have been related in any way. however, the human mind seeks organization to understand concepts and other things. the human mind therefore seeks relationships in explaining and studying the past. history being a humanity, dictates that historians have to serve this human trait by bringing structure to details of the past. historians do this by creating interpretive frameworks that capture as many details as possible."
