Question: How large was the endowment at Durham University the year that Mitchell started attending the school? Passage:Mitchell was born in London, and educated at Brightlands Preparatory School and Dulwich College, London. In 1943 he registered as a conscientious objector and his war-time service was spent in the Non-Combatant Corps. After the war, he taught at Oakfield Preparatory School, London and in 1947 founded and edited the journal Music Survey; several issues appeared before he was joined in 1949 by Hans Keller and the journal was re-launched in the Music Survey's so-called 'New Series' (194952), whose uncompromising critical standards and pugnaciously pro-Britten and pro-Schoenberg stance brought it renown and notoriety in equal measure. Mitchell studied at Durham University 1949-50. In the 1950s he was a regular contributor to the journals Musical Times and Musical Opinion. In 1958 he became editor of Music Books at Faber and Faber and in the same year was appointed Editor of Boosey & Hawkes's music journal Tempo, until 1962. From 1963 to 1964 he was a special music adviser at Boosey & Hawkes with particular responsibility for contemporary music and the acquisition of contemporary composers. He was responsible for Peter Maxwell Davies and Nicholas Maw joining the publisher's list. In 1965, with the encouragement of Benjamin Britten he founded the music-publishing firm of Faber Music, and was its first Managing Director (vice-chairman, 1976, chairman, 1977, president, 198895). In 1972 he became the first Professor of Music at Sussex University (until 1976). Following the death of Benjamin Britten, Mitchell became a senior trustee of the Britten-Pears Foundation; in 1986 he became the Foundation's director and chairman of the Britten Estate Ltd. From 1989 to 1992 he was chairman of the Performing Right Society. He was appointed a CBE in the 2000 New Year Honours, and died on 28 September 2017.

Question: How old was the conqueror of Thanjavur in 1764? Passage:Thanjavur was successfully conquered in 1674 by Ekoji I (167584), 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 (178793) 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 (183255), 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.

Question: When was the political party represented by governor Pedro Rossello founded? Passage:In 1993, the chairman of the Puerto Rico Electric Power Authority (AEE), Miguel Cordero, proposed a natural gas pipeline as part of the Government of Puerto Rico's plan to diversify Puerto Rico's energy sources. However, the proposal did not proceed during the administration of the Partido Nuevo Progresista (PNP) governor Pedro Rossello (19932000). In 2001, the Popular Democratic Party of Puerto Rico (PPD) won the gubernatorial elections, put Sila Calderon in La Fortaleza from 2001 to 2004, and appointed Hector Rosario as executive director of the AEE. The pipeline plan proposed by Cordero was shelved. In 2005, a natural gas pipeline project named Gasoducto del Sur (English: Southern Gas Pipeline) started construction under the PPD administration of Anibal Acevedo Vila. The Gasoducto del Sur pipeline would have transported natural gas from the EcoElectrica facilities in Penuelas to the power plant at Aguirre in Salinas. Acevedo Vila managed to complete about 25% of the Gasoducto del Sur project before being defeated by the opposing party, the PNP, in the 2008 elections. When the PNP took back La Fortaleza in 2009 via Luis Fortuno as governor, Miguel Cordero was reappointed executive director of the AEE, and the Gasoducto del Sur project, though a quarter of its way completed, was abruptly cancelled. The cancellation left the Government of Puerto Rico with a US$59million debt to the contractor, Skanska, and opened the way for the PNP's alternative project, Gasoducto del Norte. However, after strong environmental and popular opposition to the Gasoducto del Norte project, on 11 October 2012, the Puerto Rico Electric Power Authority (AEE) withdrew the entire Gasoducto del Norte Gsoducto del Norte permit application from the U.S. Army Corps of Engineers evaluation process, thereby stalling approval of the proposed pipeline indefinitely.
