What is life like for the quechua peoples?

The Quechua people are several different indigenous tribes that live in Peru, Ecuador, Bolivia, Chile, Colombia and Argentina. Because of their location in the mountains, many Quechua people are farmers or use agriculture in their daily lives, growing specific arable foods, as not all produce can grow at such high altitudes. Because of the prominence of llamas and alpacas, weaving is used to make clothes. This is done with cotton or wool and natural dyes, which are then hand-woven by women. Houses are built by men with clay bricks. Quechua people are now moving into cities to find jobs, however this has caused for people to lose their culture and language.

The answer would be plant growth.

The answer is c, i, iii, and iv. this is because farming and mining deal with harvesting raw materials, construction work falls under manufacturing, and piloting a plane is a service. ii is wrong because making bread is using  raw materials to produce goods, which would fall under the secondary sector, not primary.
