Task: Question Answering
Input (English): Passage: Most information on the social life in Vijayanagara empire comes from the writings of foreign visitors and evidence that research teams in the Vijayanagara area have uncovered. The Hindu caste system was prevalent and rigidly followed, with each caste represented by a local body of elders who represented the community. These elders set the rules and regulations that were implemented with the help of royal decrees. Untouchability was part of the caste system and these communities were represented by leaders (Kaivadadavaru). The Muslim communities were represented by their own group in coastal Karnataka. The caste system did not, however, prevent distinguished persons from all castes from being promoted to high-ranking cadre in the army and administration. In civil life, by virtue of the caste system, Brahmins enjoyed a high level of respect. With the exception of a few who took to military careers, most Brahmins concentrated on religious and literary matters. Their separation from material wealth and power made them ideal arbiters in local judicial matters, and their presence in every town and village was a calculated investment made by the nobility and aristocracy to maintain order. However, the popularity of low-caste scholars (such as Molla and Kanakadasa) and their works (including those of Vemana and Sarvajna) is an indication of the degree of social fluidity in the society.
Well-to-do men wore the Petha or Kulavi, a tall turban made of silk and decorated with gold. As in most Indian societies, jewellery was used by men and women and records describe the use of anklets, bracelets, finger-rings, necklaces and ear rings of various types. During celebrations, men and women adorned themselves with flower garlands and used perfumes made of rose water, civet musk, musk or sandalwood. In stark contrast to the commoners whose lives were modest, the lives of the empire's kings and queens were full of ceremonial pomp in the court. Queens and princesses had numerous attendants who were lavishly dressed and adorned with fine jewellery, their daily duties being light.Physical exercises were popular with men and wrestling was an important male preoccupation for sport and entertainment. Even women wrestlers are mentioned in records. Gymnasiums have been discovered inside royal quarters and records speak of regular physical training for commanders and their armies during peacetime. Royal palaces and market places had special arenas where royalty and common people alike amused themselves by watching matches such as cock fights, ram fights and wrestling between women. Excavations within the Vijayanagara city limits have revealed the existence of various types of community-based activities in the form of engravings on boulders, rock platforms and temple floors, implying these were places of casual social interaction. Some of these games are in use today and others are yet to be identified.
