Passage: The Bison football team was the winningest program in NCAA Football history with thirty-three conference championships and eight national championships (1965, 1968, 1969, 1983, 1985, 1986, 1988, 1990) before moving to Division I Championship Subdivision in 2004. In January 2012, NDSU defeated Sam Houston State University in the NCAA Division I Football Championship game becoming the 2011 season National Champions. NDSU football is a major event in the city of Fargo and the region, averaging over 18,000 fans per home game.  The Bison play their home games at the Fargodome (cap. 19,287). In January 2013, NDSU football won the NCAA Division I championship title for a second year in a row, defeating Sam Houston again. They also defeated Kansas State and hosted College GameDay (football). In January 2014, NDSU defeated Towson to win its 3rd consecutive national championship in FCS football.  It is only the 2nd team in NCAA history to achieve this feat. NDSU also defeated FBS Iowa State for their 6th consecutive win over an FBS opponent and hosted ESPN College Gameday for the 2nd straight season. January 2015, for the 2014 season, NDSU defeated Illinois State to win its 4th consecutive national championship in FCS football. The feat had never been accomplished in Division I football.  In the 2015 season, NDSU defeated Jacksonville State for a record 5th consecutive NCAA Division I FCS national championship. No football team in the modern history of the NCAA has accomplished this feat. In the 2016 season, NDSU was defeated by James Madison, 27-17, who eventually went on to win the championship. Thus ending the Bisons reign of 5 consecutive championships. The following season the Bison went on to win the FCS National Championship again for the sixth time in seven years, by beating James Madison 17-13. 
Question: How many times before 1990 did exactly two years pass between the national championships won by the Bison?

Passage: In the Governorate of Estonia, Estonians called for freedom of the press and assembly, for universal suffrage, and for national autonomy. On 29 October , the Russian army opened fire in a meeting on a street market in Tallinn in which about 8 000-10 000 people participated, killing 94 and injuring over 200. The October Manifesto was supported in Estonia and the Estonian flag was displayed publicly for the first time. Jaan Tõnisson used the new political freedoms to widen the rights of Estonians by establishing the first Estonian political party - National Progress Party. Another, more radical political organisation, the Estonian Social Democratic Workers' Union was founded as well. The moderate supporters of Tõnisson and the more radical supporters of Jaan Teemant could not agree about how to continue with the revolution, and only agreed that both wanted to limit the rights of Baltic Germans and to end Russification. The radical views were publicly welcomed and in December 1905, martial law was declared in Tallinn. A total of 160 manors were looted, resulting in ca. 400 workers and peasants being killed by the army. Estonian gains from the revolution were minimal, but the tense stability that prevailed between 1905 and 1917 allowed Estonians to advance the aspiration of national statehood. 
Question: How many years did the tense stability last? 
Answer type: Number 

Ex Output:
12.

Passage: The rebellion was led by Charles Neville, 6th Earl of Westmorland, and Thomas Percy, 7th Earl of Northumberland, who in November 1569 occupied Durham. Thomas Plumtree celebrated Mass in Durham Cathedral. From Durham, the rebels marched south to Bramham Moor, while Elizabeth struggled to raise forces sufficient to confront them. But, hearing of a large force being raised by the Earl of Sussex, the rebels abandoned plans to besiege York, and captured Barnard Castle instead. They proceeded to Clifford Moor, but found little popular support. Sussex marched out from York on 13 December 1569 with 7,000 men against the rebels' 4,500, and was followed by 12,000 men under Baron Clinton. The rebel earls retreated northward and finally dispersed their forces, fleeing into Scotland. 
Question: How many more men did the Earl have than the rebels? 
Answer type: Number
