(c) both created both religious and economic benefits in their respective societies. (d) both led to a significant increase in food production by allowing farming in previously impossible locations.

Explanation:

A chinampa is an ancient method of agriculture and territorial expansion. It is a raft made with logs that then was covered with very good quality soil since it contained biodegradable materials such as grass, leaf litter, fruit and vegetable peels. A willow tree was planted in the chinampa so that its roots would grow from the water to the mainland on the banks of lagoons and streams. After the willow tree grew, they planted different crops that they later harvested. Flowers and vegetables were grown in the chinampas. Thanks to this technique, it is said that the Aztec culture built real floating cities.

The cultivation terraces in East Asia  were made in order to take advantage of agricultural land. It is an ancient agricultural practice through which true architectural and complex engineering works were built to produce food and self-supply. Transverse and flat edges (terraces) were built on the ground to allow cultivation on the steep slopes of the mountains and hills.   The terraces incorporate a channel above the edge to control the runoff waters. Water is captured on the terrace and extends through the cultivation field. Most terraces have a slight downward angle to allow excess water to drain to the next level.
