Q: Question: What was the population of Los Angeles the year that Spears did her interview with Seacrest? Passage 1:Garcia Bacca studied under the Claretians and became a priest in 1925. He continued his formative studies at the University of Munich, University of Zurich and the University of Paris. Yet he quit the Church during the 1930s and began to study philosophy at the University of Barcelona. In 1936 he went into exile because of his criticism of Francisco Franco, traveling first to Ecuador, where he taught at the Central University of Ecuador (1939–42) where he became a close friend with the writer Alfredo Pareja Diezcanseco, then to México, where he taught at the UNAM (1942–46) and finally establishing in Venezuela in 1946 and becoming a Venezuelan citizen in 1952. He started teaching upon his arrival at the Central University of Venezuela in 1946 until his retirement in 1971. He won the National Prize for Literature in 1978 for his life's work.
 Passage 2:On 26 March 2015, it was announced that Treweek was to become the next Bishop of Gloucester, the diocesan bishop of the Diocese of Gloucester. Though there had been two women appointed bishops previously in the Church of England, she was the first woman to be appointed a diocesan bishop, rather than as a suffragan bishop. She was the first woman to become a bishop in the Province of Canterbury, jointly with Sarah Mullally, Bishop of Crediton. On 15 June 2015, her election was confirmed during a sitting of the Arches Court of Canterbury at St Mary-le-Bow, City of London. At this point, she legally became the Bishop of Gloucester. On 22 July 2015, she was consecrated a bishop by Justin Welby, the Archbishop of Canterbury, during a ceremony at Canterbury Cathedral. She and Sarah Mullally (later Bishop of London) were the first women to be ordained as bishops at Canterbury Cathedral. On 19 September, she was installed at Gloucester Cathedral as the 41st Bishop of Gloucester.
 Passage 3:"Piece of Me" was co-written and produced by the Swedish duo Christian Karlsson and Pontus Winnberg, professionally known as Bloodshy & Avant, along with Klas Åhlund. While recording with Spears over the years, Karlsson and Winnberg often saw first-hand how her regular activities were interrupted by the paparazzi, including one experience in Hamburg which Winnberg deemed "really scary". For Blackout, Spears worked with them on "Radar", "Freakshow" and "Toy Soldier". When the album was considered to be finished, Bloodshy & Avant were persuaded by her A&R Teresa LaBarbera Whites to work on a new track. Winnberg commented that it had always been an unwritten rule not to write songs about Spears's personal life since the label rejected "Sweet Dreams My LA Ex", a response track to Justin Timberlake's "Cry Me a River". However, the duo wrote "Piece of Me" with Åhlund and sent it to Spears, who loved it. Bloodshy & Avant worked on the track at Bloodshy & Avant Studios in Stockholm, Sweden, and Spears recorded her vocals at Chalice Recording Studios in Los Angeles, California. Winnberg stated that Spears was extremely psyched when she came to the studio, where she recorded the song in about half an hour as she had learned the lyrics by heart in her car. "Piece of Me" was later mixed by Niklas Flyckt at Mandarine Studios in Stockholm. On October 31, 2007, during a radio interview with Ryan Seacrest, Spears talked about the song, saying,
