Passage: On September 30, 1581, Nobunaga launched his own invasion of Iga on a much larger scale. The immediate trigger for this second invasion was a visit by two residents of Iga the month before to Nobunaga's stronghold in Azuchi during which the men offered to serve as guides for an invasion of the province. Nobunaga agreed and rewarded the men. By this time Oda was at the height of his power. He controlled most of central Japan, including all of the territories that bordered Iga. He was therefore able to assemble a large army which attacked the province from all directions: 1. 10,000 men under the command of Nobukatsu and Tsuda Nobusumi entering from Ise  to the southeast.2. 12,000 men under Niwa Nagahide and Takigawa Kazumasu entering from Tsuge to the northeast.3. 7,000 men under Gamō Ujisato and Wakisaka Yasuharu entering from Tamataki to the north.4. 3,700 men under Tsutsui Junkei entering from Kasama to the southwest.5. 7,000 men under Asano Nagamasa entering from Hase to the southwest.6. 2,300 men under Hori Hidemasa entering from Tarao to the northwest. Against this large army of 42,000 men, the Iga defenders only totaled 10,000 at most, and these were spread throughout the province. The Oda forces advanced, torching castles, shrines, and temples, and meeting relatively little resistance. The most significant military actions were the siege of Hijiyama Castle, which had become the rallying point for the northern Iga forces, and the siege of Kashiwara Castle in the south. With the surrender of the forces in Kashiwara Castle on October 8, organized Iga resistance came to an end. Nobunaga himself toured the conquered province in early November, and then withdrew his troops, placing control in Nobukatsu's hands. 
Question: How many different forces were involved on the attacking end of the second invasion? 
Answer type: Number 
6.

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?
