Q: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Passage: The local language Kannada was mostly used in Western (Kalyani) Chalukya inscriptions and epigraphs. Some historians assert that ninety percent of their inscriptions are in the Kannada language while the remaining are in Sanskrit language. More inscriptions in Kannada are attributed to Vikramaditya VI than any other king prior to the 12th century, many of which have been deciphered and translated by historians of the Archaeological Survey of India. Inscriptions were generally either on stone (Shilashasana) or copper plates (Tamarashasana). This period saw the growth of Kannada as a language of literature and poetry, impetus to which came from the devotional movement of the Virashaivas (called Lingayatism) who expressed their closeness to their deity in the form of simple lyrics called Vachanas. At an administrative level, the regional language was used to record locations and rights related to land grants. When bilingual inscriptions were written, the section stating the title, genealogy, origin myths of the king and benedictions were generally done in Sanskrit. Kannada was used to state terms of the grants, including information on the land, its boundaries, the participation of local authorities, rights and obligations of the grantee, taxes and dues, and witnesses. This ensured the content was clearly understood by the local people without any ambiguity.In addition to inscriptions, chronicles called Vamshavalis were written to provide historical details of dynasties. Writings in Sanskrit included poetry, grammar, lexicon, manuals, rhetoric, commentaries on older works, prose fiction and drama. In Kannada, writings on secular subjects became popular. Some well-known works are Chandombudhi, a prosody, and Karnataka Kadambari, a romance, both written by Nagavarma I, a lexicon called Rannakanda by Ranna (993), a book on medicine called Karnataka-Kalyanakaraka by Jagaddala Somanatha, the earliest writing on astrology called Jatakatilaka by Sridharacharya (1049), a writing on erotics called Madanakatilaka by Chandraraja, and an encyclopedia called Lokapakara by Chavundaraya II (1025).
