Input: Question: What was the attendance at the University of Lyons the year that Minyi became the Vice President of the Institut Franco-Chinois? Passage 1:Linda was introduced as the wife of Mick Carter, played by Danny Dyer, the brother of established character Shirley Carter (Linda Henry), who has appeared in EastEnders since 2006. Luisa Bradshaw-White joined the cast as Shirley's sister Tina Carter in early November, and Linda was the second new Carter to appear after her. Kellie Bright's casting was announced alongside Danny Dyer's on 1 October 2013, a week after Bradshaw-White's casting was revealed. Linda was described as having been with Mick since they were teenagers, and despite not being 'blessed with brains', is a 'tough woman who will always fight tooth and nail for her family - especially her children'. Bright previously appeared as a bridesmaid in 1986 at the wedding of Michelle Fowler (Susan Tully) and Lofty Holloway (Tom Watt), and starred in scenes opposite her current co-star Letitia Dean, who continues to appear as Sharon Watts. Bright estimated herself to be aged 10 at the time. She also auditioned for the role of Tanya Branning in 2006, a role that was eventually given to Jo Joyner.
 Passage 2:In November 1911, after the start of the Xinhai Revolution, he returned to Shanghai, where he became local leader of the Tongmenghui movement in the city. However, he disagreed with Song Jiaoren over the establishment of the Kuomintang, and left China for Belgium, where he earned degrees in medicine and pharmacology at the Free University of Brussels, but he never went into medical practice. He returned briefly to China in 1915 to oppose Yuan Shikai’s attempt to establish a new Chinese Empire, but soon returned to Europe. In 1921, he became the Vice President of the Institut Franco-Chinois which Li Shizeng had founded at the University of Lyons and held the post for a year. In 1922 he moved to Strasbourg, and received his doctorate from the University of Strasbourg in 1925.
 Passage 3:Of the population of 176,125 (2002), 45% live in the capital, Palencia which is located on the Canal de Castilla. There are 191 municipalities in the province, of which more than half are villages with fewer than 200 people. The major towns in this province are: Guardo, an industrial-mining town; Aguilar de Campoo, a biscuit and tourist village in northern Palencia; Herrera de Pisuerga, a village that is the gateway to the Palencine mountain, is also known for its summer activities and Crab Festival; Venta de Baños, an important railway and industrial junction south of the province; Villamuriel de Cerrato, a village to the south of Palencia that owes its development to the Renault factory and its proximity to Palencia; Cervera de Pisuerga, in the heart of the Palencine mountains; Barruelo, a mining town that was the most populated town until the 1960s. During the Middle Ages, the Visigoths ruled Palencia. Basílica de San Juan, the oldest Visigothic church in Spain, was built in 661 in the province's Baños de Cerrato. During the thirteenth century a university was founded in the province. It was the first university in Spain and one of the first in the world. It was later shifted to Valladolid.
