Answer:
Wow! I just answered this question.
Step-by-step explanation:
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.
I hope this helps!
