Explain what the quipu was and how it was used. what was its drawback?

answer: the quipu was a system of knotted strings used by the inca people for keeping records. while the quipu can remember time and dates, it cannot substitute writing. a kings time period may be written, but his name is not. a general may give a mnemonic to a messenger, but the messenger has to remember the message himself. the quipu, in order to be fully effective, must have a witness from the past to show who and what was apart of each specific time period.
