Answer: b) People of the Southwest developed systems of canals to divert water from nearby rivers to irrigate their crops.
Explanation:
The Hopi were part of the western Pueblo tribes, while the Hohokam were the ancestors of the Pima and Tohono O’odham, and were located in the western and southern limits.
Their developments in agriculture required access to rivers, smaller streams, and seasonal waterways, so they built stone canals to irrigate their fields.
