Step-by-step explanation:
The Guarani Indians of Paraguay primarily relied on a subsistence strategy that included a combination of agriculture, hunting, and gathering. They cultivated crops such as manioc and maize, which formed the bulk of their diet. In addition, they hunted wild animals and gathered fruits, nuts, and honey from their environment to supplement their agricultural yields.
