Why do you think that records do not exist before 1500 B. C.E.? * THIS IS FOR ANCIENT CHINA*
( NEED HELP ASAP! )

yo this is just a geuss, i have not even learned about that subject yet, but maybe it is because they did not know How to keep records. Maybe they were not smart enough to keep them. Or maybe it is because they had no access to the technology to keep records. don't fail the class because of my advise though.

Explanation:

Again don't be completly reliant on this answer, i'm literally a  middle school student that has no education on this topic.  i hope it helps!

demand is the need and oportunity to buy a given good or service.

the outcome of 1970 oil crisis in united states was that, they began to search ways on how to reduce oil.

in 1970 was a period when there were energy and oil crisis. those who were major centers for industrialization were forced to keep way from supplying of petroleum.

some of the result of this crisis was economic growth became stagnant because prices of oil surged.

due to the increased prices some countries like mexico and norway benefited.
