The correct answers are A) a source of food, C) a source of milk, hides, and wool, and D) a source of money.
Domesticated animals provided these three things to pastoral people: a source of food, C) a source of milk, hides, and wool, and D) a source of money.
Pastoral people were humble people and in some cases poor people that only had their domesticated animals for surviving. They had cattle, cows, pigs, chicken and a few portions of land in the best cases, for farming. So with these resources, they had to make a living. So that is why domesticated animals represented a patrimony on those years. They were a source of food, a source of milk, hides, and wool, and a source of money.
