Context: Elaine Chan Yu Ning (; born March 15, 1988) is a two-time Olympic swimmer from Hong Kong, specialized in freestyle events.  At age sixteen, Chan first competed at the 2004 Summer Olympics in Athens, where she finished forty-seventh in the women's 50 m freestyle, with a time of 27.48 seconds.  Following her remarkable performance at the Olympics, Chan granted a full scholarship to the Ohio State University in Columbus, Ohio, where she trained with the college swimming team for 18 months.  In 2007, Chan returned to Hong Kong to pursue her education with a bachelor's degree in economics and finance at the University of Hong Kong, while she trained with the national team in preparation for the Olympics.  She qualified for the 2008 Summer Olympics in Beijing, and competed for the second time in women's 50 m freestyle.  She swam in the seventh heat of the competition, with a time of 26.54 seconds, bettering her personal best from the previous Olympics, but finishing only in forty-fourth place. Russia has competed at the modern Olympic Games on many occasions, but as different nations in its history.  As the Russian Empire, the nation first competed at the 1900 Games, and returned again in 1908 and 1912.  After the Russian revolution in 1917, and the subsequent establishment of the Soviet Union in 1922, it would be thirty years until Russian athletes once again competed at the Olympics, as the Soviet Union at the 1952 Summer Olympics.  After the dissolution of the Soviet Union in 1991, Russia competed as part of the Unified Team in 1992, and finally returned once again as "Russia" at the 1994 Winter Olympics. The Netherlands Antilles competed at the 2004 Summer Olympics in Athens, Greece, from 13 to 29 August 2004, sending track athletes Churandy Martina and Geronimo Goeloe and equestrian athlete Eddy Stibbe.  The 2004 Games were the Netherlands Antilles' twelfth appearance in the Summer Olympics; they first competed at the 1952 Summer Olympics in Helsinki, Finland.  Before the 2004 games, the Netherlands Antilles had won one medal, a silver in sailing at the 1988 Summer Olympics, by Jan Boersma.  There were no Dutch Antillean medalists at the Athens Olympics, although Martina advanced to the quarterfinal round in his event.  The Dutch Antillean flagbearer at the ceremonies was Churandy Martina. Russia has competed at the modern Olympic Games on many occasions, but as different nations in its history.  As the Russian Empire, the nation first competed at the 1900 Games, and returned again in 1908 and 1912.  After the Russian revolution in 1917, and the subsequent establishment of the Soviet Union in 1922, it would be thirty years until Russian athletes again competed at the Olympics, as the Soviet Union at the 1952 Summer Olympics.  After the dissolution of the Soviet Union in 1991, Russia competed as part of the Unified Team in 1992, and finally returned again as Russia for the 1994 Winter Olympics. Raymond L. Ocampo, Jr. (born February 10, 1953) is a retired Filipino-American luger.  He represented the Philippines at the 1988 Winter Olympics.  He participated at the Winter Olympics' men's singles event where he ranked 35 out of 38 overall.  His Winter Olympic stint was almost put in jeopardy due to some issues with the kind of passport he should be holding to represent the Philippines at the Olympics.  The Philippine Olympic Committee eventually allowed him to compete under the Philippine flag without a Philippine passport despite previously requiring Ocampo the said type of passport.  Ocampo previously insisted that under the rules by the IOC that he as a Filipino-American dual citizen is eligible to represent the Philippines as he did not competed for another country as a luger prior to the Olympics.  Ocampo first competed at the 1986 Empire State Games.  Ocampo is also a lawyer. El Salvador first competed in the Olympic Games at the 1968 Summer Olympics in Mexico City, Mexico.  No athletes were sent to the 1976 Summer Olympics, and the nation took part in the boycott of the 1980 Summer Olympics.  Excluding these two Games, El Salvador has participated in every Summer Olympic Games since 1968.  It has never competed in the Olympic Winter Games.  As of the completion of the 2012 Summer Olympics, 118 Salvadorians (93 male and 25 female) have represented their nation at the Olympics.  No Salvadorian has ever won an Olympic medal. The Germany Olympic football team represents Germany in international football competitions in Olympic Games.  It has been active since 1908, and first competed in 1912.  Olympic football was originally an amateur sport, and as the pre-World War II German national team was also amateur, it was able to send a full national team to the games.  After the war, Germany was divided, but until 1964 East and West competed under the name of "United Team of Germany", although without a combined squad.  From 1968 West Germany began to compete on its own, but were still forced to send an amateur team, who were not able to match the success of their professional counterparts in the World Cup and European Championship.  The rules on amateurism were relaxed in the 1980s, which allowed West Germany some success, notably a bronze medal finish in 1988.  Since 1992 the tournament has been competed by under-23 teams, making Germany's Olympic qualification dependent on the results of the under-21 team.  Only in 2016 the Germans returned to the Olympic stage, with a silver medal after losing on a penalty shoot-out to hosts Brazil.  Reunified Germany is now the only World Cup champion without the Olympic gold. Manfred Eglin (10 October 1935 – 10 August 2001) was a German footballer who played as a goalkeeper.  Born in Karlsruhe, Eglin played for Karlsruher FV and Stuttgarter Kickers, and represented Germany in the 1956 Summer Olympics. Palestine first competed at the Summer Olympics in 1996.  The Palestinian National Authority is represented on the International Olympic Committee by the Palestine Olympic Committee, which has sent teams to compete at each Summer Olympics since 1996 under the IOC country code PLE.  Palestine has been recognized as a member of the Olympic Council of Asia (OCA) since 1986, and the International Olympic Committee (IOC) since 1995.  The Palestinian Olympic committee did not work with the Israeli Olympic committee to train for the 2012 Olympic games, and participation in the 2013 Mediterranean Games. After declaring independence from Russia in 1918, Estonia first competed as a nation at the 1920 Summer Olympics, although the National Olympic Committee was established in 1923.  The first Winter Olympics were the 1924 Winter Olympics.  Estonian athletes took part in the Olympic Games until the country was invaded and occupied by the Soviet Union in 1940.  The 1980 Summer Olympics Sailing regatta was held in the capital city Tallinn.  After the end of the Soviet occupation in 1991, Estonia has participated in all Olympics.  Estonia has won most of its medals in wrestling (11), weightlifting (7), cross-country skiing (7) and athletics (6).
