Q: 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?

Q: Passage: Pittsburgh entered week eleven with starters having missed 31&#160;games due to injuries. The San Diego Chargers scored first, and led 7-0 after the first quarter of play. On the second play of the second quarter, the Steelers' James Harrison forced a fumble in the endzone, then forced a safety by tackling Marcus McNeill after he had recovered the fumble. Jeff Reed converted on a field goal as time expired on the first half, pulling the Steelers within two points. Reed kicked his second field goal of the game from 41-yards to give the Steelers the lead going into the final quarter. The Chargers drove 74&#160;yards on 17&#160;plays, converting on a field goal to give them the lead again, with 6:45 remaining. On the Steelers' ensuing drive, the offense drove 73&#160;yards and Reed converted on his third field goal of the day, giving the Steelers an 11-10 lead with 15&#160;seconds remaining in regulation. The Chargers attempted to score on their final play, but Troy Polamalu forced and recovered a fumble, returning it for a touchdown. The call was reversed when the officials ruled that San Diego had made an illegal forward pass. After the game, head referee Scott Green admitted that the touchdown should have been counted. With the touchdown not counted the final score kept Pittsburgh under the 5&#160;point spread by which they were favored, and resulted in over $32&#160;million being lost in bets. The game was the first regular season game in NFL history to end with a final score of 11-10.
