Explanation:
The Incas were known for their advanced farming and building techniques. In terms of farming, they developed a system known as terrace farming, in which they would cut flat areas out of steep hillside slopes. This allowed them to cultivate more food on less land, taking advantage of their mountainous environment. They also created a sophisticated irrigation system to water these terraces.
In terms of building, the Incas are known for their masonry skills. Their buildings were made of large stone blocks that fit together perfectly without any mortar. This technique is known as ashlar masonry. They also constructed large fortresses and temples, like Machu Picchu, which showcased their advanced use of materials and understanding of architectural principles.
