Which cultivation constraint limited the size of raised chinampa plots in pre-Columbian Mesoamerica?

💡 Explanation

Digging without metal tools constrained chinampa size because manual digging effort increased exponentially with surface area due to soil saturation. Therefore, plots were limited to a manageable scale, rather than allowing unbounded enlargement leading to prohibitively difficult construction.
