Question: What did Lerdorf contribute to the Apache HTTP Server? Passage 1:Golay was born in Windsor, Missouri, on July 2, 1915, and served in the United States Navy during World War II. After his military service, Golay obtained a doctorate in economics from the University of Chicago in 1951, and worked for the Federal Reserve Board until 1953, when he joined the Cornell University as an assistant professor of economics and Asian studies. In 1960, Golay received a Guggenheim fellowship. He was named chair of the Cornell Department of Economics in 1963, and left the position in 1967. He taught at SOAS, University of London as a visiting professor on a Fulbright grant from 1965 to 1966. Between 1970 and 1976, Golay led the Cornell Southeast Asia Program. Golay was a visiting professor at the University of the Philippines from 1973 to 1974 as a recipient of a Rockefeller Foundation grant. He retired from Cornell in 1981, and served as president of the Association for Asian Studies in 1985. Golay died on August 31, 1990, at the veterans' hospital in Oxford, New York.
 Passage 2:Brazil faced Chile in the round of 16, taking an 18th-minute lead through David Luiz's first goal for the Seleção. With no further scoring after Alexis Sánchez's equaliser, the match went to a penalty shootout. Brazil prevailed 3–2, with Neymar, David Luiz and Marcelo converting their kicks, and goalkeeper Júlio César saving from Chileans Sánchez and Mauricio Pinilla. The team again faced South American opposition in the quarter-final, defeating Colombia 2–1 with goals from central defenders David Luiz and team captain Thiago Silva. Late in the match, Neymar was substituted on a stretcher after Camilo Zúñiga's knee had made contact with the forward's back. Neymar was taken to hospital and later diagnosed with a fractured vertebra, which ruled him out for the remainder of the tournament. Prior to this, Neymar had scored four goals, provided one assist and been named man of the match twice. Brazil faced further problems ahead of their semi-final against Germany, as Thiago Silva was to serve a one-match suspension for receiving his second yellow card of the tournament in the quarter-final. The Seleção went on to lose 1–7 to the Germans, their biggest ever defeat at the World Cup and first home loss in a competitive match since 1975. Towards the end of the match, the home crowd began to "olé" each pass from the German team, and booed their own players off the pitch after the final whistle. The match has been nicknamed the Mineirazo, making reference to the nation's previous World Cup defeat on home soil, the Maracanazo against Uruguay in 1950, and the Estádio do Mineirão in Belo Horizonte where the match took place.
 Passage 3:Lerdorf was born on Disko Island in Greenland and moved to Denmark in his early years. Lerdorf's family moved to Canada from Denmark in 1980, and later moved to King City, Ontario in 1983. He graduated from King City Secondary School in 1988, and in 1993 he graduated from the University of Waterloo with a Bachelor of Applied Science in Systems Design Engineering. He contributed to the Apache HTTP Server and he added the LIMIT clause to the mSQL DBMS. A variant of this LIMIT clause had already been around for a decade in mainframe relational database management systems (like Oracle Rdb running on VAX/VMS, formerly from Digital Equipment Corporation), but apparently it had not yet been picked up by the emerging PC-based databases. It was later adapted by several other SQL-compatible DBMS. He released the first version of PHP in 1995.

Question: Is Liverpool the capital of a country? Passage 1:Louisiana French (, Louisiana Creole: françé la lwizyàn) refers to the complex of dialects and varieties of the French language spoken traditionally in colonial Lower Louisiana. As of today Louisiana French is primarily used in the U.S. state of Louisiana, specifically in the southern parishes, though substantial minorities exist in southeast Texas as well. Over the centuries, the language has incorporated some words of African, Spanish, Native American and English origin, sometimes giving it linguistic features found only in Louisiana, Louisiana French differs to varying extents from French dialects spoken in other regions, but Louisiana French is mutually intelligible with all other dialects and particularly with those of Missouri, New England, Canada and northwestern France. Many famous books, such as Les Cenelles, a poetry anthology compiled by a group of gens de couleur libres, and Pouponne et Balthazar, a novel written by French Creole Sidonie de la Houssaye, are in standard French. It is a misconception that no one in Louisiana spoke or wrote Standard French. Figures from the United States Census record that roughly 3.5% of Louisianans over the age of 5 report speaking French or a French-based creole at home. Distribution of these speakers is uneven, however, with the majority residing in the south-central region known as Acadiana. Some of the Acadiana parishes register francophone populations of 10% or more of the total, with a select few (such as Vermilion, Evangeline and St. Martin Parishes) exceeding 15%.
 Passage 2:Baptised in Liverpool 23 September 1833 in the heart of the city's slums he was the son of a brushmaker, also called William Hodgkins. His mother had been Jane Grocott or Groocock and his sister Jane was born in 1835. William Mathew went to school at Staveley, Derbyshire and his exercise book in penmanship survives, prefiguring his adult career as a law clerk and lawyer and his lifelong interest in graphics. By 1852 his father was in business in Birmingham but William Mathew was a law clerk in London. He lived in Holborn, worked for Waterlow and Sons, famous printers of stamps and bank notes, and for the Patent Office. By 1855 he was in Paris where he assisted in 'literary work' at Versailles, perhaps copying correspondence or graphic works. Back in London about 1857 he studied Turner's paintings and other artists, at Hampton Court and the National Gallery. In 1859 he worked at the National Portrait Gallery in London.
 Passage 3:The Bogd Khanate of Mongolia was the government of Mongolia (Outer Mongolia) between 1911 and 1919 and again from 1921 to 1924. By the spring of 1911, some prominent Mongolian nobles including Prince Tögs-Ochiryn Namnansüren persuaded the Jebstundamba Khutukhtu to convene a meeting of nobles and ecclesiastical officials to discuss independence from the Manchu-led Qing China. On November 30, 1911 the Mongols established the Temporary Government of Khalkha. On December 29, 1911 the Mongols declared their independence from the collapsing Qing Empire following the Xinhai Revolution. They installed as theocratic sovereign the 8th Bogd Gegeen, highest authority of Tibetan Buddhism in Mongolia, who took the title Bogd Khaan or "Holy Ruler". The Bogd Khaan was last khagan of Mongolia. This ushered in the period of "Theocratic Mongolia", also known as the Bogd Khanate.

 Passage 3:After spending many years training in the United Kingdom the 197th Brigade, together with the rest of the 59th Division, landed in France on 29 June 1944, D-Day + 23. The division, under command of XII Corps, became part of the British Second Army, which was engaged in the Battle for Caen. With the arrival of the 59th Division General Bernard Montgomery, commanding the Anglo-Canadian 21st Army Group, decided to renew the offensive to capture the city of Caen, which was originally a D-Day objective for the British 3rd Infantry Division which ultimately failed, due mainly to heavier resistance than expected. Operation Charnwood. The brigade's first action was Operation Charnwood with 2/6th South Staffords (of 177th Brigade), along with C Company of the 7th Battalion, Royal Northumberland Fusiliers (the divisional MG Battalion), together with numerous units of the Royal Artillery under command (and 510 Field Company, RE), and supported by the Churchill tanks of the 1st East Riding Yeomanry (of 27th Armoured Brigade). The brigade suffered comparatively light casualties in Charnwood. The 197th Brigade later fought in the Second Battle of the Odon, and the Battle of the Falaise Gap.
