Q: Passage: A large portion of the Vilnius area was controlled by the Second Polish Republic during the interwar period, particularly the area of the Republic of Central Lithuania, which had a significant Polish speaking population. For example, the Wilno Voivodeship (25% of it is a part of modern Lithuania and 75% - modern Belarus) in 1931 contained 59.7% Polish speakers and only 5.2% Lithuanian speakers; see Ethnic history of the region of Vilnius for details. From 1918 to 1921 there were several conflicts, such as the activity of the Polish Military Organization, Sejny uprising (that was met with massive outrage in Lithuania) and a discovered attempt at a Polish coup on the Lithuanian government. From the documents stolen from Polish Military Organization headquarters safe in Vilnius and given to Prime Minister of Lithuania Augustinas Voldemaras, it is clear that this plot was directed by Józef Piłsudski himself. The Polish-Lithuanian War and Żeligowski's Mutiny contributed to a worsening of Polish-Lithuanian relations; increasingly Polish people were viewed with suspicion in Lithuania. The loss of Vilnius was a stunning blow to Lithuanian aspirations and identity, and the unrelenting irredentist demand for its return became one of the most important elements of Lithuanian political and social life in the interwar period. The irredentist campaign resulted in the emergence of feelings of hatred and revenge directed against the Poles in the Lithuanian society. In fact, the largest social organization in interwar Lithuania was the League for the Liberation of Vilnius, which propagated irredentist views in its magazine Mūsų Vilnius (Our Vilnius).

Q: Passage: Columbia (; ) is the female personification of the United States. It was also a historical name used to describe the Americas and the New World. It has given rise to the names of many persons, places, objects, institutions and companies; for example: Columbia University, the District of Columbia (the national capital of the United States), and the ship Columbia Rediviva, which would give its name to the Columbia River. Images of the Statue of Liberty largely displaced personified Columbia as the female symbol of the United States by around 1920, although Lady Liberty was seen as an aspect of Columbia. The District of Columbia is named after the personification, as is the traditional patriotic hymn "Hail Columbia", which is the official vice presidential anthem of the United States Vice President.
 Link Information: Established in 1754 Question: In what year was Columbia University founded?

A: Answer: 1754

Q: Passage: As an amateur, Doherty won the Irish Amateur Championship twice, the World Under-21 Amateur Championship and the World Amateur Championship. Having turned professional in 1990, Doherty has won a total of six ranking tournaments, including the 1997 World Snooker Championship in which he defeated Stephen Hendry, inflicting Hendry's first loss in a world final. This made him the first player, and so far one of only two (the other being Stuart Bingham) to have been world amateur and professional champion. The following year, he came very close to breaking the Crucible curse, reaching the 1998 final where he lost out to John Higgins. He reached a third final in 2003, in which he was defeated by Mark Williams. In other triple crown events, he is a three-time UK Championship runner-up and a two-time Masters runner-up.
