Example Input: 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 
Example Output: 6.

Example Input: Passage: The 8-1 Bengals traveled to Arizona to face the 7-2 Cardinals and former Bengals #1 overall draft pick Carson Palmer. In the first quarter, the Bengals would strike first as Dalton found Tyler Eifert on a 3-yard touchdown pass to give them a 7-0 lead for the only score of the period. In the second quarter, the Cardinals would tie the game when Palmer found Darren Fells from 18 yards out to tie things up at 7. The Bengals would retake the lead as Jeremy Hill ran into the endzone from 2 yards out to give them a 14-7 lead at halftime. In the 3rd quarter, it was all Cardinals, as Carson Palmer found J.J Nelson for a 64-yard touchdown to tie the game at 14. Arizona would take their first lead of the game as Palmer found John Brown from 18 yards out to give them a 21-14 lead. The Cardinals would extend the lead as Palmer found David Johnson from 16 yards out to extend the lead to 28-14.  In the fourth quarter, the Bengals would cut into the lead as Hill ran in his second touchdown of the night, this one from 1 yard out, to cut the deficit to 28-21. After a Dalton fumble, Chandler Catanzaro would extend the Arizona lead to 31-21. However, the Bengals would make the game close once again, as Eifert caught his second touchdown of the night, cutting the lead to 31-28. Cincinnati would tie the game 31-31 on a Mike Nugent field goal. However, Palmer and the Cardinals offense went right down the field to get into the field goal range. The most notable part of this drive, and, perhaps, the game, was an unsportsmanlike conduct penalty by Bengals defensive tackle Domata Peko. The penalty was for mimicking the count during the huddle. The penalty made the field goal easier, and Catanzaro nailed the game winner from 32 yards out as time expired to end the game. With the loss, the Bengals fell to 8-2. The loss also dropped them to 0-4 all time against the Cardinals on the road, and 0-3 all time against them in Arizona. 
Question: How many points were the Bengals leading by at halftime? 
Answer type: Number 
Example Output: 7.

Example Input: Passage: After the Treaty of Versailles, treaties with Austria, Hungary, Bulgaria, and the Ottoman Empire were signed. However, the negotiation of the treaty with the Ottoman Empire was followed by strife, and a final peace treaty between the Allied Powers and the country that would shortly become the Republic of Turkey was not signed until 24 July 1923, at Lausanne. Some war memorials date the end of the war as being when the Versailles Treaty was signed in 1919, which was when many of the troops serving abroad finally returned home; by contrast, most commemorations of the war's end concentrate on the armistice of 11 November 1918. Legally, the formal peace treaties were not complete until the last, the Treaty of Lausanne, was signed. Under its terms, the Allied forces left Constantinople on 23 August 1923. 
Question: How many years after the Treaty of Versaille was signed was the treaty with Turkey at Lausanne signed?
