Question: Is the university of Paris in France? Passage:Following his completion of secondary school, Demiéville spent time studying in Munich, London, and Edinburgh, where he was able to attend lectures by George Saintsbury at the University of Edinburgh. He then attended the University of Paris, where he wrote an essay on the musical suite of the 17th and 18th centuries and was awarded a licentiate degree in 1914. Demiéville then spent the year 1915 studying at King's College London where he was introduced to Chinese, which quickly became his focus. After returning to France, Demiéville studied at the École des Langues Orientales Vivantes (School of Living Oriental Languages), after which he moved to the Collège de France, where he further studied Chinese under the tutelage of Édouard Chavannes and began learning Sanskrit from Sylvain Lévi. He earned his Diplômé from the École des Langues Orientales Vivantes in 1919.

Question: How many years did the war last where the castle was strengthened in the middle of it? Passage:In 1575, in the middle of the Wars of Religion, the castle was strengthened. It was nevertheless besieged and taken by the Geuzen, locally known as the Hurlus in 1579, before being taken back three months later. In 1627, Philip IV of Spain promoted the seigneury to the rank of county. The Franco-Dutch War under Louis XIV devastated this mostly agricultural region. Mouscron and the surrounding area became French after the Treaty of Aix-la-Chapelle (1668). Part of it rejoined the Southern Netherlands after the Treaty of Nijmegen (1678), which drew the frontier right through its territory. It was finally completely ceded to the Southern Netherlands under the terms of the Treaty of Utrecht in 1713. The textile industry started in Mouscron in the 1760s thanks to the imposition by Lille of a ban on the fabrication of molletons, a mixture of flax and wool, in Roubaix and Tourcoing. With the Battle of Fleurus (1794), Mouscron went back to France.

Question: What was the population of Muirhouse in 1955? Passage:Irvine Welsh was born in Leith, the port area of the Scottish capital Edinburgh. He states that he was born in 1958, though, according to the Glasgow police, his birth record is dated around 1951. When he was four, his family moved to Muirhouse, in Edinburgh, where they stayed in local housing schemes. His mother worked as a waitress. His father was a dock worker in Leith until bad health forced him to quit, after which he became a carpet salesman; he died when Welsh was 25. Welsh left Ainslie Park High School when he was 16 and then completed a City and Guilds course in electrical engineering. He became an apprentice TV repairman until an electric shock persuaded him to move on to a series of other jobs. He left Edinburgh for the London punk scene in 1978, where he played guitar and sang in The Pubic Lice and Stairway 13, the latter a reference to the Ibrox disaster. A series of arrests for petty crimes and finally a suspended sentence for trashing a North London community centre inspired Welsh to correct his ways. He worked for Hackney London Borough Council in London and studied computing with the support of the Manpower Services Commission.
