Example Input: Question: How long had the Algerian war been going on when Kopanski was 14? Passage:In 1962, when only 14, he was fascinated by the success of the Arab national and anti-colonial forces that defeated the French colonial armies in the Algerian War, gaining independence for their country. When attending a military college in Kętrzyn (Ger. Rastenburg) in 1966-1969, he actively opposed the Polish communist regime during the 1968 Polish political crisis, and as a result was expelled from the Officer School, and became a political prisoner for the first time. He continued his studies at the University of Silesia in Katowice, and after graduation was employed there as a lecturer,adiunct and researcher. In 1980-81, when Poland was swept by a wave of anti-communist strikes, and around ten million joined the anti-communist Solidarity trade union, Kopański co-founded a branch of this broad grassroots social movement at the University of Silesia.

Example Input: Question: Did Ivan's brother die in battle? Passage:A member of the Aspietes family, of noble Armenian origin, Constantine was probably a close relative of his contemporary Michael Aspietes, a distinguished general killed in 1176. Like his relative, Constantine too had earned distinction during Manuel I Komnenos' campaign against the Hungarians in 1167. The historian John Kinnamos records that he held the rank of sebastos. He is next recorded as being active in 1190/1, during the Byzantine efforts to suppress the Bulgarian–Vlach rebellion of the brothers Peter and Ivan Asen. The historian Niketas Choniates records that, in an effort to sustain the troops and bolster their morale, Aspietes decided to distribute to them their delayed annual salaries. This act, however, enraged Emperor Isaac II Angelos, who saw in it almost an attempt to bribe the army to support Aspietes in overthrowing him. The emperor had Aspietes arrested and blinded, after which nothing further is known of him. He possibly died in the early years of the 13th century.

Example Input: Question: How many years after its creation did the Far East Air Forces move to Hawaii? Passage:After World War II, the Air Force in Hawaii consisted primarily of the Air Transport Command and its successor, the Military Air Transport Service (MATS), until 1 July 1957 when Headquarters Far East Air Forces completed its move from Japan to Hawai‘i and was redesignated the Pacific Air Forces (PACAF). The 15th Air Base Wing, host unit at Hickam AFB, supported the Apollo astronauts in the 1960s and 1970s; Operation Homecoming (return of prisoners of war from Vietnam) in 1973; Operation Babylift / New Life (movement of nearly 94,000 orphans, refugees, and evacuees from Southeast Asia) in 1975; and NASA's space shuttle flights in the 1980s and 1990s. Hickam is home to the 65th Airlift Squadron which transports theater senior military leaders throughout the world in the C-37B and C-40 Clipper aircraft. In mid-2003, the 15th Air Base Wing (15 ABW) was converted to the 15th Airlift Wing (15 AW) as it prepared to beddown and fly the Air Force's newest transport aircraft, the C-17 Globemaster III. The first Hickam-based C-17 arrived in February 2006, with seven more to follow during the year. The C-17s will be flown by the 535th Airlift Squadron.
