Which benefit did chinampa construction provide for agricultural production in the Valley of Mexico?

💡 Explanation

Construction of chinampas involved dredging nutrient-rich mud from the lake bottom, creating fertile platforms because this continually provided a supply of essential elements for plant growth. Therefore, improved nutrient availability results, rather than frost protection, water retention, or disease reduction, which require different environmental or structural properties.
