Why is it necessary to study animal products and pastures together to understand pastoral economy?

Correct answer: Animal products depended on animal health and pastures

Animal products cannot be understood separately from pastures because the quality and availability of grazing affect animal health. Well-fed and healthy animals generally produce more milk, wool and other useful outputs. Pastures also provide the food needed to maintain herds, so seasonal changes, drought or restrictions on grazing can reduce production and income. This shows a chain: access to pasture supports healthy animals, and healthy animals support the pastoral economy.

Option A is correct because it explains this connection between natural resources, animal condition and production. Option B is false because pastures directly feed animals. Option C is impossible because milk and wool come from animals, and option D incorrectly limits common resources to kings. The question encourages an integrated view: to understand products and earnings, one must also study grazing land, water, movement and herd care.
