← HistoryWhich mechanism enabled sufficient maize production despite Lake Texcoco's salinity for the Aztec Triple Alliance?
A)Chinampa raised-bed filtration✓
B)Crop rotation saline reduction
C)Terrace irrigation drainage
D)Open-field selective breeding
💡 Explanation
Chinampa agriculture leveraged 'raised-bed filtration', where sediments naturally filtered out salts, therefore enabling maize cultivation because fresh water accessed by the roots leached the toxic salts; this is rather than attempting broad field treatment.
