Input: Consider Input: Passage: On 19 April 1918, Detachment Brandenstein took over the town of Lahti. The German troops advanced from the east-southeast via Nastola, through the Mustankallio graveyard in Salpausselkä and the Russian garrisons at Hennala. The battle was minor but strategically important as it cut the connection between the western and eastern Red Guards. Local engagements broke out in the town and the surrounding area between 22 April and 1 May 1918 as several thousand western Red Guards and Red civilian refugees tried to push through on their way to Russia. The German troops were able to hold major parts of the town and halt the Red advance. In total, 600 Reds and 80 German soldiers perished, and 30,000 Reds were captured in and around Lahti. 
Question: How many days was the time span where local engagements broke out in the town and surrounding area as several thousand western Red Guards and civilian refugees tried to push through on their way to Russia?

Input: Consider Input: Passage: Following two consecutive losses to Dallas and San Diego, Philadelphia went to Chicago to take on the Chicago Bears, who were 4-5, on Sunday Night Football. The Eagles dominated the first quarter as Philadelphia took a two score lead on a 25-yard field goal by David Akers and a 13-yard touchdown from Donovan McNabb to Jason Avant on a wide receiver screen pass. Down 10-0 at the start of the second quarter, Chicago drove within one point as Bears kicker Robbie Gould successfully made a 45-yard field goal, as well as a pair of 28-yard field goals, to make the score 10-9 at the half. In the second half, the Bears took the lead as Robbie Gould kicked his fourth field goal, a 49-yarder that put Chicago up 12-10. However, it took only 30 seconds for the Eagles to take the lead as Donovan McNabb passed to DeSean Jackson for a 48-yard touchdown to give the Eagles a 17-12 lead. Ironically, the 48-yard touchdown catch was the shortest touchdown scored by Jackson thus far in the season. Chicago again took the lead in the third quarter as struggling quarterback Jay Cutler, who had already missed several wide open targets in the game, passed to tight end Kellen Davis for a 15-yard score. The Bears converted the 2-point conversion attempt as running back Matt Forte scored on the pass from Cutler to put the Bears back on top 20-17. In the fourth quarter, both defenses fought back and forth but the only points of the final period were scored by Eagles running back LeSean McCoy on a 10-yard, game-winning touchdown run to put the Eagles up 24-20, the game's final score. With the win, the Eagles improved to 6-4. Ironically, the Eagles win came by the same score (24-20) in the same city (Chicago) at the same time and venue (Sunday Night Football on NBC) as when they had lost in week 4 of the 2008 season. 
Question: How many field goals did Akers kick in the first quarter? 
Answer type: Number 

Output: 1.


Input: Consider Input: Passage: The governor of Louisiana and founder of New Orleans, Jean-Baptiste Le Moyne de Bienville determined to stop Chickasaw trade with the British. In 1721 he was able to incite the Choctaw who began to raid Chickasaw villages, and to ambush pack trains along the Trader's Path leading to Charleston, South Carolina. In response, the Chickasaw regrouped their villages more tightly for defense, and cemented relations with their British source of guns by establishing a settlement at Savannah Town, South Carolina, in 1723. They blocked French traffic on the Mississippi River by occupying Chickasaw Bluff near present day Memphis, and bargained for peace with the Choctaw. Bienville himself was recalled to France in 1724 . On and off over the following years, the French successfully reignited the Indian conflict. The Choctaw pursued their familiar hit and run tactics: ambushing hunting parties, killing trader's horses, devastating croplands after using superior numbers to drive the Chickasaw into their forts, and killing peace emissaries. Illini and Iroquois occasionally pitched in from the north as well. This war of attrition effectively wore the Chickasaw down, reaching a crisis level in the late 1730s and especially the early 1740s. After a lapse due to strife within the Choctaw, the bloody harassment resumed in the 1750s. The Chickasaw remained obstinate, their situation forcing them to adhere even more closely to the British. In 1734, Bienville returned to Louisiana, and waged grand campaigns against the Chickasaw in the European style. 
Question: How many northern tribes helped the Choctaw? 
Answer type: Number 


Output: 2.
