To determine the answer, we need to analyze the characteristics of the Andes Mountains and the challenges they present to the Inca civilization. The Andes Mountains are commonly known for their rocky and steep terrain located in South America.
Considering this information, we can eliminate options A (heavy rain), C (hot climate), and D (dry conditions) since these factors do not specifically relate to the rocky and steep nature of the mountains.
Option B, which is thin air, is the most appropriate choice. The Andes Mountains consist of high altitudes, with some peaks reaching over 6,000 meters (20,000 feet). At such high elevations, the amount of oxygen in the air decreases, resulting in thinner air. This presents a significant challenge for human habitation and survival as it can cause altitude sickness, shortness of breath, and decreased physical performance.
Therefore, the Inca people had to adapt to the thin air of the Andes Mountains to ensure their survival and successful civilization.
