The most suitable answer to your question is: the Nazca Culture.
In the southern of Peru are located the Nazca Lines, created by the pre Inca civilization, the Nazcas. The Nazca lines are collection of geoglyphs made in the soil. These geoglyphs are of a great cultural relevance since you can see the design of animals, plants, and figurative designs. These designs can be seen from the air and it is believed that the Nazca people created them to be seen by their Gods in the sky.
Hope this helps.
The culture of Nazca was responsible for the geoglyphs. It is an archaeological culture that was developed in the current department of Ica in the first century. This civilization is responsible for the creation of the Nazca lines that represent gigantic figures of animals, people and geometric designs made on a large scale and with absolute precision. There are several theories on why these geoglyphs, the best known and accepted is that it would be a giant astronomical calendar. Another possibility is that it was a sacred place where the people performed religious ceremonies.
he Incas, an American Indian people, were originally a small tribe in the southern highlands of Peru. In less than a century, during the 1400s, they built one of the largest, most tightly controlled empires the world has ever known. ... Roads, walls, and irrigation works constructed by the Incas are still in use today.
Just took the test and I can confirm that D. Lower Classes was the correct answer ;)
Most likely Conquered people. They would be the ones doing the work.
