Not exactly sure what the question is..
I'll try to help if you can give a more detailed question below!
Thanks! :)
I know for sure that it is the first and second one but i think the last answer will be your number 3.
I sure don't have time to write an essay! But the first one sounds alright.
One of the early Chinese civilizations was located between the two main rivers, (google them for more details) Anyways, unlike most of China, the plain between the two rivers is fertile, allowing the people to grow rice and other foods. Along with that, I am certain that they had mountains and deserts to the west. If they could be used against natural disasters (I doubt they'd come in west) it'd be helpful! Good day
