Input: Consider Input: Question: How old was the conqueror of Thanjavur in 1764? Passage:Thanjavur was successfully conquered in 1674 by Ekoji I (1675–84), the Maratha feudatory of the sultan of Bijapur and half-brother of Shivaji (1627/30-80) of the Bhonsle dynasty. Ekoji founded the Thanjavur Maratha kingdom which ruled Thanjavur till 1855. The Marathas exercised their sovereignty over Thanjavur throughout the last quarter of the 17th and the whole of the 18th century. The Maratha rulers patronized Carnatic music. In 1787, Amar Singh, the regent of Thanjavur, deposed the minor Raja, his nephew Serfoji II (1787–93) and captured the throne. Serfoji II was restored in 1799 with the assistance of the British, who induced him to relinquish the administration of the kingdom and left him in charge of Thanjavur fort and surrounding areas. The kingdom was eventually absorbed into British India in 1855 by the Doctrine of Lapse when Shivaji II (1832–55), the last Thanjavur Maratha ruler, died without a legitimate male heir. The British referred to the city as Tanjore in their records. Five years after its annexation, the British replaced Negapatam (modern-day Nagapattinam) with Thanjavur as the seat of the district administration. Under the British, Thanjavur emerged as an important regional centre. The 1871 India census recorded a population of 52,171, making Thanjavur the third largest city in the Madras Presidency. After India's independence, Thanjavur continued as the district headquarters.

Input: Consider Input: Question: How large was Israel's GDP the year Dayan emigrated to that country? Passage:Yosef Dayan emigrated to Israel in 1968, and became a member of the right-wing Kach movement. Dayan is the founder of "Malchut Israel", a right-wing religious-political group in Israel advocating a return of the monarchy. In 2004, he became a member of the newly reconstituted Sanhedrin, a duplicate of the religious tribunal which convened during the time of the Second Temple, a group that had traditionally had seventy-one members. He has also achieved certain notoriety for his alleged central participation in so-called "death curse" ceremonies or Pulsa diNura aimed at Yitzhak Rabin and Ariel Sharon. These curses were presumably to request divine retribution after those former Prime Ministers advocated Israeli withdrawal from certain areas considered by some as inalienable parts of the promised land. Incidentally, Yitzhak Rabin was murdered soon after the first curse, and Ariel Sharon left in a persistent vegetative state after a brain haemorrhage following the second. He is also known to have supported Baruch Goldstein's (a fellow Meir Kahane disciple) terrorist actions in the Cave of the Patriarch's Massacre.
