Which benefit primarily drove the adoption of chinampa construction by the Mexica civilization around Lake Texcoco?

💡 Explanation

Chinampas, or 'floating gardens,' were constructed to drain marshland and create fertile raised beds. The increased agricultural intensification in limited space resulted because of constant access to water and nutrient recruitment from the lake's bottom. Therefore agricultural yield was maximized, rather than erosion control etc., which involved other techniques.
