Question: Passage: In the late 16th and early 17th centuries, Russia was in a state of political and economic crisis. After the death of the Tsar Ivan IV  in 1584, and the death of his son Dimitri in 1591, several factions competed for the tsar's throne. In 1598, Boris Godunov was crowned to the Russian throne, marking the end of the centuries long rule of the Rurik dynasty. While his policies were rather moderate and well-intentioned, his rule was marred by the general perception of its questionable legitimacy and allegations of his involvement in orchestrating the assassination of Dimitri. While Godunov managed to put the opposition to his rule under control, he did not manage to crush it completely. To add to his troubles, the first years of the 17th century were exceptionally cold. The drop in temperature was felt all over the world, and was most likely caused by a severe eruption of a volcano in South America. In Russia, it resulted in a great famine that swept through the country from 1601 to 1603. 
Question: How many years did the great famine last that swept through Russia? 
Answer type: Number 

Answer: 2.


Question: 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? 
Answer type: Number 

Answer: 3.
