Question
History

Which consequence emerged historically when the artificial island infrastructure of Mesoamerican chinampas became oversaturated?

A)Increased nutrient availability for maize
B)Elevated root disease susceptibility in maize
C)Improved aeration within the soil
D)Enhanced carbon sequestration in the soil

💡 Explanation

The oversaturation triggered anaerobic conditions restricting oxygen because it promoted proliferation of bacteria, causing root rot disease in maize due to inadequate root respiration; therefore disease increased, rather than the other effects, which need drained soils.
