Which outcome primarily resulted from the adoption of terrace farming in the ancient Andes?

💡 Explanation

When slopes were transformed to terraces, leveled surfaces retained water and topsoil, impeding runoff because the stepped topography slowed water flow. Therefore agricultural productivity increased, rather, than drought vulnerability, increased salinity, or frost damage which are not due to this mechanism of water retention enhancement via terrace design.
