Example Input: Question: How old was Gabriel Bethlen when his forces sacked Vienna? Passage:At the time, the Thirty Years' War was raging across Europe. Gabriel Bethlen, prince of Transylvania saw an opportunity to unite the two Hungarian principalities, Transylvania and Royal Hungary, and sacked Vienna in November 1619. He also asked Sultan Osman II for aid, but this was unsuccessful. The Commonwealth was relatively uninvolved in this war but the Polish king, Zygmunt III Waza, sent an elite and ruthless mercenary unit, the Lisowczycy, to aid his Habsburg allies. They defeated the Hungarian lord George Rákóczi at the Battle of Humenné in 1619, and thus, cut the supply lines of Transylvanian forces. Then Gaspar Graziani, ruler of Moldavia, switched sides and joined Poland.

Example Input: Question: Which of the two countries that the Soviets sent troops to in January 1991 had the larger army? Passage:On 12 May 1990 the leaders of the Baltic republics signed a joint declaration known as the Baltic Entente. By mid-June the Soviets started negotiations with the Baltic republics on condition they agreed to freeze their declarations of independence. The Soviets had a bigger challenge elsewhere, in the form of the Russian Federal Republic proclaiming sovereignty in June. Simultaneously the Baltic republics also started to negotiate directly with the Russian Federal Republic. In Autumn 1990, they set up a customs border between the Baltic states, the Russian Federation and Belarus. After the failed negotiations the Soviets made a dramatic attempt to break the deadlock and sent troops to Lithuania and Latvia in January 1991. The attempts failed, dozens of civilians were killed, and the Soviet troops decided to retreat. In August 1991, the hard-line members of the Soviet government attempted to take control of the Soviet Union. One day after the coup on 21 August, the Estonians proclaimed independence. Shortly afterwards Soviet paratroops seized the Tallinn television tower. The Latvian parliament made similar a declaration at the same day. The coup failed but the Collapse of the Soviet Union became unavoidable. On 28 August, the European Community welcomed the restoration of the sovereignty and independence of the Baltic states. The Soviet Union recognised the Baltic independence on 6 September 1991. The Russian troops stayed for an additional three years, as Boris Yeltsin linked the issue of Russian minorities with troop withdrawals. Lithuania was the first to have the Russian troops withdrawn from its territory in August 1993. On 26 July 1994 Russian troops withdrew from Estonia and on 31 August 1994, Russian troops withdrew from Latvia. The Russian Federation ended its military presence in Estonia after it relinquished control of the nuclear facilities in Paldiski on 26 September 1995 and in Latvia after Skrunda-1 suspended operations on 31 August 1998 and subsequently dismantled. The last Russian soldier left Skrunda-1 in October 1999, thus marking a symbolic end to the Russian military presence on the soil of the Baltic countries.

Example Input: Question: Who owns the team that Taylor began a 2 year apprenticeship with? Passage:Taylor was a pupil at Moorside High School in Swinton, Greater Manchester and was associated with Manchester United as a schoolboy until he was not offered a scholarship at Old Trafford at the age of 16. In July 2015 he began a two-year apprenticeship at Nottingham Forest's youth-team. On 30 August 2019, he joined EFL League Two side Port Vale on loan after impressing manager John Askey in training games during a trial spell. Taylro said that "Port Vale have strong links with Forest, as you have seen with Adam Crookes and also Toby Edser came in. Phil Sproson is good friends with the academy manager Gary Brazil so the link is there. They have shown an interest and I have jumped at it." He made his debut the following day, coming on as a 67th-minute substitute for Cristian Montaño in a 1–0 win over Cambridge United at Vale Park. He later said that "I knew it would be physical but I think I have dealt with that quite well. Probably the speed of the game has surprised me." On 24 September, he scored his first goal in senior football in a 3–2 victory at Macclesfield Town in the EFL Trophy. He scored his first league goal four days later, bending the ball into the top corner from the edge of the penalty area in a 3–3 draw at Leyton Orient. On 2 November, he scored the only goal of the game at local rivals Crewe Alexandra.
