Answer: C. Working animals made farming and transportation easier.
Explanation: Working animals made farming easier as indigenous peoples could use working animals to plow fields, pull heavy loads, and carry agricultural produce. This increased their efficiency and productivity in farming, leading to better food production and improved livelihoods.
In addition, working animals improved transportation. Horses and llamas were used as pack animals, allowing indigenous peoples to transport goods over long distances more easily. This facilitated trade and communication between different communities and regions, expanding their access to resources and opportunities.
