Example Input: Question: What city was Jet Ski Lady's last race in? Passage:Jet Ski Lady (foaled 20 February 1988) was an American-bred, Irish-trained thoroughbred racehorse, best known for winning The Oaks in 1991. In a racing career which lasted from June 1990 to October 1991 the filly ran ten times and won four races. After winning twice as a two-year-old, Jet Ski Lady competed against colts with mixed success in early 1991 before winning the Classic Oaks over one and a half miles at Epsom Downs Racecourse. Her winning margin of ten lengths was the second-widest in the race's history and her starting price of 50/1 made her the equal longest-priced winner of the Oaks on records. She subsequently finished second in both the Irish Oaks at the Curragh and the Yorkshire Oaks at York. She was retired to stud after finishing unplaced in the Prix de l'Arc de Triomphe.

Example Input: Question: What was the standard tuition for the Empress Alexandra Russian Muslim Boarding School for Girls in 1906? Passage:Maryam Bayramalibeyova was the daughter of Azerbaijani historian and journalist Teymur Bayramalibeyov and his wife Shirin (née Talyshinskaya), a Russian-educated Talysh-Azerbaijani who translated a number works by classical Russian writers into Azeri and was famous for promoting Western culture in Lankaran and the neighbouring regions. In 1906 Maryam Bayramalibeyova was accepted to the Empress Alexandra Russian Muslim Boarding School for Girls in Baku and 7 years later, to Saint Nina's Secondary Boarding School. In 1917, she graduated from Saint Nina's with honours and was admitted to study medicine at Moscow State University. However, after the October Revolution, being a daughter of an upper-middle class literatus Bayramalibeyova considered her life to be in danger and returned to Lankaran (eventually she did manage to get a post-secondary education receiving an Honours B.A. in law from Baku State University later in 1931). In her native city in 1917, she established the first all-girls secular school (named Uns) in the entire uyezd (administrative unit in Czarist Russia) with the help of Teymur Bayramalibeyov, and became its first principal. The Bayramalibeyovs visited many families in Lankaran encouraging them to send their daughters to Uns. The courses were taught in the Russian language. In order to promote the arts, Maryam Bayramalibeyova organized drama, choir, and musical clubs in the school, which apparently was a success as two of her students later became prominent Azerbaijani actresses and one became a renowned mugham singer. In 1919, Bayramalibeyova founded the Lankaran Women's Charity Association.

Example Input: Question: How many years had the Cold War been going on at this point? Passage:During the presidential campaign of 1948, as Cold War fears of communist global expansion mounted, critics of the Truman administration heatedly raised the question "Who Lost China?." Criticism mounted after Truman's surprising victory in the election as the Communist Party of China led by Mao Zedong steadily defeated Chinese Nationalist armies of Chiang Kai-shek and was winning the Chinese Civil War. In November 1948 John Paton Davies proposed a collection of documents to explain and defend American policy in China to the American public, an idea that Secretary of State Dean Acheson ordered his staff to prepare. The group was headed by the Director of the Far Eastern Division, Walton Butterworth but much of the work was done by John F. Melby, who had served for the State Department in the Soviet Union and China during the war, and by Charles Yost. The 1054 page volume was published August 1949, as Mao and his retinue waited outside the city of Beiping, as Beijing was then called,
