Q3561. Consider the following statements regarding the specialized committees (Variyams) of the Chola Sabha: I. The Totta-variyam was responsible for managing village gardens and orchards. II. The Pon-variyam managed matters related to gold and local currency. III. The Nyaya-variyam was specifically tasked with overseeing foreign maritime trade. Which of the above combinations of statements is correct?
Explanation
The Chola administrative system utilized specialized committees for efficient local management. The Totta-variyam oversaw gardens and orchards, while the Pon-variyam handled matters related to gold and local currency. These descriptions are accurate. However, the Nyaya-variyam was actually responsible for judicial matters and the administration of justice at the village level, rather than overseeing foreign maritime trade, which was typically the domain of powerful merchant guilds or the central government.

Q3565. What was a major consequence of the increasing use of the ‘Ijara’ (revenue farming) system in the later medieval period in Rajasthan?
Explanation
The expansion of the Ijara, or revenue farming system, had a detrimental impact on rural society. Because Ijaradars were motivated by personal profit, they often extracted as much as possible from the peasantry beyond the official demands. This practice led to severe exploitation and financial distress, as the middlemen lacked long-term interest in the welfare of the land or cultivators.

Q3566. What was the specific name of the lottery-based election system used to select committee members for the village assemblies during the Chola period?
Explanation
The Cholas employed a unique and democratic lottery system called Kudavolai to select members for their village committees. Under this method, the names of eligible candidates were written on palm-leaf slips and placed into a pot (kuda). A young boy was then asked to draw the slips one by one to determine the winners. This system was designed to ensure fairness and prevent any single individual or family from monopolizing local political power.
