Answer: The correct answer is knowing the ways that humans use Earth's natural resources.
Explanation:
The ancient settlers of the Andean region, at the foot of the Andes Mountains developed extraordinary irrigation and cultivation systems on the hillsides. The crops were deployed in the form of steps on the hillside making productive all the resources provided by nature and adding technology for its efficient and effective use.
The current farmers use some of the techniques and customs inherited from the original peoples and add the most modern technologies to further increase the productivity of the lands and contribute positively to the economy of their regions.
It is a common feature in the diverse cultures of humanity to adapt to the geographical characteristics of the region where they live solving the difficulties through ingenuity and hard work.
According to one theory by British archaeologist Mortimer Wheeler, a nomadic, Indo-European tribe, called the Aryans, suddenly overwhelmed and conquered the Indus River Valley.
