Answer :
Final answer:
The most useful Inca advancement for a farmer on a steep mountain is the use of terraces for agriculture. This method allows for effective cultivation on slopes and reduces soil erosion. Other options, such as chaski, quipu, and trephination, do not relate to farming needs.
Explanation:
Inca Agricultural Advancements
A farmer living on the edge of a steep mountain would benefit most from the Inca advancement of terraces. Terracing is an ancient agricultural method where flat areas are created on hilly or mountainous terrain, allowing for the efficient cultivation of crops despite the slope. This technique not only maximizes arable land but also helps combat soil erosion, which is crucial in steep landscapes.
For example, the Inca civilization famously used terracing to grow a variety of crops, such as potatoes and corn, by constructing steps on the mountainsides. This innovation allows farmers to utilize otherwise challenging land for agriculture, making it easier to manage water drainage and microclimates that can support different plant growth. Therefore, the correct choice for the farmer would be:
- C. A terrace
Other Options Explained
- A chaski refers to a messenger in the Inca Empire, which does not directly assist in farming.
- A quipu is a method of record-keeping using knotted strings, also unrelated to agriculture.
- Trephination is a medical procedure and has no relevance to farming.
