Input: Consider Input: Question: How many total albums have the Swedish pop group ABBA released? Passage:The Definitive Collection is a 2001 compilation album of all the singles released by Swedish pop group ABBA. It consisted of two discs: the first featuring the singles from 197279 ("People Need Love" to "Does Your Mother Know"), and the second including the singles from 197982 ("Voulez-Vous" to "Under Attack"), with the tracks being listed in chronological order. The main exception is the track "Thank You for the Music", which, despite being written and recorded in 1977, was in fact released as a single (primarily in the UK) in 1983 after the band had split up. It appears on disc two, along with two bonus tracks, "Ring Ring" (1974 UK single remix), and "Voulez-Vous" (1979 US promo extended remix). The Australian version of The Definitive Collection adds a further two bonus tracks: "Rock Me" and "Hasta Manana". The 1974 remix of "Ring Ring" is the first appearance on CD of this version mastered from the original master tape, after the UK single master tapes had been returned to Polar Music by the former UK licensees, Epic Records. The track's previous appearance on CD, in a 1999 singles boxed set, was mastered from a vinyl single.

Input: Consider Input: Question: How long did the empire that modified the fort during the 13th century last? Passage:Originally the site of a small fort built by the Chola dynasty during the 9th century AD, Gingee Fort was modified by Kurumbar while fighting the Cholas and again by the Vijayanagar empire during the 13th century. As per one account, the fort was built during the 1516th century by the Gingee Nayaks, the lietunants of the Vijayanagara Empire and who later became independent kings. The fort was built at a strategic place to fend off any invading armies. It was further strengthened by the Marathas under the leadership of Shivaji in 1677 AD. He recaptured it from the Bijapur sultans who had originally taken control of the fort from the Marathas. In 1691, it was besieged by Mghal generals Zul Fikar Khan, Asad Khan & Kam Baksha but was successfully defended by Santaji Ghorpade. During Aurangzeb's campaign in the Deccan, Shivaji's second son who had assumed the throne, Chhatrapati Rajaram, escaped to Ginjee and continued the fight with Moghuls from Ginjee. The fort was the seat of the Maratha Empire for a few months. The Moghuls could not capture the fort for seven years in spite of laying siege. The fort was finally captured in 1698, but not before Chhatrapati Rajaram escaped. It was later passed on to the Carnatic Nawabs who lost it to the French in 1750 before the British finally took control in 1761 despite losing it to Hyder Ali for a brief period. Raja Desingh ruled Gingee during the 18th century.
