In pre-Columbian chinampa agriculture, which outcome resulted from the need to elevate planting beds?

💡 Explanation

Higher elevation increases exposure to air, causing aerobic decomposition releasing minerals into topsoil. The mechanism of nutrient mineralization resulted in increased soil fertility for optimal agricultural output, rather than preventing flooding or generating dessication because of micro-organism activity. Therefore, the most reasonable outcome is A.
