How could the movement of pastoral communities become a service for local society?

They provided useful services like manure animal products and transport of goods

Pastoral communities could serve local society because their animals and skills supported many rural needs. Manure could help farmers improve soil, animal products could be exchanged or sold, and pack animals could carry goods between places. Such exchanges created links between mobile pastoralists and settled farmers. Their movement was therefore not necessarily separate from local life; it could contribute to production, trade and transport.

Option A is correct because it names useful economic services. The other options deny social contact or describe activities unrelated to the question. Pastoralists were not simply outsiders with no role in villages. Their contribution varied by region and group, but manure, animal products and transport are clear examples of how their work could benefit others. The answer follows from their connection with the wider rural economy.
