Why did the mayans create a detailed writing system?
a. to keep track of trade
b. to keep track of the seasons
c. to keep track of political rulers - i think it's c
d. to keep track of families

I believe the correct answer from the choices listed above is option C. The Mayans create a detailed writing system because to keep track of political rulers. It is now thought that the codices and other Classic texts were written by scribes, usually members of the Maya priesthood, in a literary form of the Ch’olti’ language. Hope this helps.
