Statement II: These agreements significantly boosted the state revenues and brought prosperity to the local Banjara traders.

British Political Agents used their leverage to secure salt agreements that gave the British control over local salt resources.

Instead, the salt monopoly caused economic hardship for the traditional Banjara communities who relied on the salt trade.Statement I: The Lomas Rishi cave in the Barabar hills features a finely polished interior and a decorated entrance facade.
