Explanation: Gift exchange and redistribution had an important economic role in the Rig Vedic society. Such exchanges, known as ‘prestations’, were done not on an individual level but at the group level.

• Apart from economic goods, this also included the exchange of other things such as women, courtesies, hospitality, and military assistance.
• The priests received dana (gifts) and dakshina (sacrificial offering) for their ritualistic services.
• Shifting agriculture was practiced and fire was used to burn down forest cover and the patch of land thus cleared was then sown. Apart from yava or barley, no other grain is mentioned.
• They did not use iron technology but were familiar with copper. Also, there have been very few references to metallurgical activities.
