Problem: About 2,600-2,800 Soviet prisoners of war were handed over to the Germans in exchange for roughly 2,200 Finnic prisoners of war held by the Germans. In November 2003, the Simon Wiesenthal Center submitted an official request to Finnish President Tarja Halonen for a full-scale investigation by the Finnish authorities of the prisoner exchange. In the subsequent study by Professor Heikki Ylikangas it turned out that about 2,000 of the exchanged prisoners joined the Russian Liberation Army. The rest, mostly army and political officers, , most likely perished in Nazi concentration camps.

How many Finnic soldiers did not join the Russian Liberation Army?
Answer: 200

Problem: The Oakland Raiders traveled to INVESCO Field at Mile High for Sunday Night Football on October 15. The Raiders arrived in Denver 0-4 while the Broncos began the game tied for first place in their division at 3-1. This game was again primarily a defensive struggle. Oakland had two turnovers deep in Broncos territory, one an interception thrown by Andrew Walter that was picked off by Champ Bailey, and another a fumble by LaMont Jordan. Neither team was able to do much on offense, with just 1 touchdown scored in the entire game (a run by Tatum Bell) and a total of 274 yards produced by the Raiders and 246 yards by Denver. The only turnover of the game by Denver came on a Darrent Williams fumble on a punt return early in the second half. Jason Elam succeeded on kicks from 51 and 22 yards, while Sebastian Janikowski scored the only points for Oakland on a 47-yard field goal in the third quarter. Randy Moss had 86 yards receiving, while Javon Walker had 75 yards. Both had 1 50+ yard catch to put their teams in scoring position. Tatum Bell was the leading rusher with 83 yards. With the win, the Broncos improved to 4-1. The Broncos by this point had only allowed 1 touchdown in 52 opponent possessions. In this game they became the first team since the 1934 Detroit Lions to go five games while allowing only one touchdown to be scored against them.

How many more yards did the Raiders produce than Denver?
Answer: 28

Problem: 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.

How many seasons did NDSU score the same amount of points against James Madison?
Answer: 2

Problem: Before order was finally restored, angry mobs had destroyed or damaged more than 350 buildings, including the residence of the Home Minister and 70 percent of the police boxes in the city. Casualties included 17 people killed, over 450 policemen, 48 firemen and civilians injured, and hundreds arrested. News of the Tokyo violence touched off similar disturbances in Kobe and Yokohama and further stimulated hundreds of nonviolent rallies, speeches, and meetings throughout Japan for the next several months. This unrest directly contributed to the collapse of Prime Minister Katsura Taro's cabinet on 7 January 1906. The Hibiya Incendiary Incident marks the beginning of a period in Japanese history that historians call the Era of Popular Violence . Over the next 13 years Japan would be rocked by a series of violent protests , culminating in the Rice riots of 1918.

How many years did these events start for?
Answer:
12
