Which outcome was LEAST likely to result from poorly-maintained terrace systems in pre-Columbian Andean agriculture?

💡 Explanation

When terraces are poorly maintained, erosion and soil destabilization occurs because the supporting structures are weakened, leading to more soil movement, decreased soil quality, and more landslides. Therefore the only option physically implausible is water table contamination, rather than the other options that involve failure to contain and retain material.
