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.

the story goes that because of this belief, constantine was able to defeat his foes. constantine became an ardent1 christian. christianity and other religions were tolerated under constantine's rule. constantine also was responsible for the building of a great cathedral in rome.

should be the answer hope this

explanation: we can only guess at how our actions may be perceived in the future. doing something really big like killing lots of people, saving lots of people, affecting the lives of lots of people is a sure fire way of being remembered in historical records. we can also make a difference in the history records by being a small influence on something bigger, whether that is as a civil servant, scientist or artist.

of course you could argue that we all affect history just as tiny cogs in a   bigger machine.

if you mean how do people influence our opinions of things which have already happened, then simply by writing a book which looks at things form a different perspective and trying to convince people that this perspective is more accurate or truthful. people do it all the time i.e. richard the third was a terrible or was he? plenty would disagree, it's just that their views aren't the most widely known.n:
