Answer:
C. The Aztecs shifted from hunting to farming.
Step-by-step explanation:
The Aztecs were a group of people dependent mostly on nature and moving from one place to another in search of food. This hunting-gathering practice stopped when they had to escape to the swampy island of Tenochtitlan in Lake Texcoco.
The nomadic life of the Aztec people changed when they had to settle on that swampy island. Instead of the usual hunting, they learned how to cultivate and farm crops, building causeways to get to the mainland. Most specifically, the creation of the settlement helped the Aztec people to shift from hunting to farming.
Thus, the correct answer is option C.
