Which of the following was NOT a result of the agricultural methods used by the Inca?

The choice indicating soil erosion is not a result of the agricultural methods used by the Inca because, although soil erosion can occur in agricultural practices, the Incas were notably skilled in developing techniques to prevent it. They implemented advanced terrace farming, which not only maximized arable land on their mountainous terrain but also included innovative drainage systems that helped maintain soil integrity. This careful management of their environment fostered sustainable agricultural practices that mitigated erosion rather than exacerbated it.

In contrast, the agricultural methods of the Inca led to increased food production, which was crucial as it supported population growth. Thriving food supplies allowed for larger communities and eventually urban development, especially in regions like Cusco. These outcomes resulted from the Incas' ability to cultivate diverse crops and create a highly organized agricultural system across their expansive empire.
