Which benefit primarily resulted from Aztec civilization using chinampa construction for maize cultivation within Lake Texcoco?

💡 Explanation

When chinampas are constructed, sediments dredged from the lakebed, rich in organic matter, are added to the raised beds, providing continuous nutrient replenishment because decomposition processes release minerals. Therefore nutrient replenishment results, rather than salinization prevention, which requires drainage management or flood retention which needs physical barriers.
