[Q]: Passage: The February Revolution had toppled Tsar Nicolas II of Russia, and replaced his government with the Russian Provisional Government. However, the provisional government was weak and riven by internal dissension. It continued to wage World War I, which became increasingly unpopular. A nationwide crisis developed in Russia, affecting social, economic, and political relations. Disorder in industry and transport had intensified, and difficulties in obtaining provisions had increased. Gross industrial production in 1917 had decreased by over 36% from what it had been in 1914. In the autumn, as much as 50% of all enterprises were closed down in the Urals, the Donbas, and other industrial centers, leading to mass unemployment. At the same time, the cost of living increased sharply. Real wages fell about 50% from what they had been in 1913. Russia's national debt in October 1917 had risen to 50 billion rubles. Of this, debts to foreign governments constituted more than 11 billion rubles. The country faced the threat of financial bankruptcy.
Question: When did the February Revolution occur?
[A]: date

[Q]: Passage: Trying to make it 5 straight wins and stay in contention for the No.3 seed in the AFC playoffs, the Chargers continued their domination over the Denver Broncos on Christmas Eve. Not only did they stop them from scoring a touchdown for the second time this season they also made it 4 straight victories over Denver. The game started off inauspiciously for the Broncos when Denver QB Jay Cutler fumbled the ball leading to a 40-yard K Nate Kaeding field goal for San Diego, and after a 3 and out, the Chargers gave the ball to RB LaDainian Tomlinson for a 17-yard TD run. The second quarter was relatively quiet as 2 Kaeding Field goals (23-yards & 29-yards) gave the Bolts a 16-point lead going into halftime. In the third quarter San Diego QB Philip Rivers and WR Chris Chambers hooked up on a 14-yard pass and catch to make the score 23-0. Denver finally began to move offensively until a tipped pass was intercepted by San Diego SS Clinton Hart, but some defensive miscues including a San Diego QB Billy Volek fumble led to a 23-yard field goal by Denver K Jason Elam. In the fourth quarter the defense stepped up for the Bolts on 2 fourth down plays and a San Diego CB Quentin Jammer interception sealed the victory for San Diego. The result guaranteed that a San Diego win at Oakland would secure the No.3 seed in the AFC playoffs. The win in Denver at home made San Diego only the second team in NFL history to shut out every opponent at home in the first quarter, outscoring opponents 81-0.
Question: How many field goals did Nate Kaeding have?
[A]: number

[Q]: Passage: The disintegration of the Pagan Empire was now complete. But the Mongols refused to fill in the power vacuum they had created. They would send no more expeditions to restore order. The emperor apparently had no interest in committing troops that would be required to pacify the fragmented country. Indeed, his real aim all along may have been "to keep the entire region of Southeast Asia broken and fragmented." It would be another two years until one of Narathihapate's sons, Kyawswa, emerged as king of Pagan in May 1289. But the new "king" controlled just a small area around the capital, and had no real army. The real power in central Burma now rested with the three commander brothers. The uneasy arrangement would persist until 1297. The Mongols continued to occupy northern Burma to Tagaung as the province of Zhengmian but ended the fictional central Burma province of Mianzhong on 18 August 1290. Meanwhile, the power struggle in central Burma continued with the three brothers blatantly consolidating support. To check their rising power, Kyawswa submitted to the Mongols in January 1297, and was recognized by the Yuan emperor Temur Khan as King of Pagan on 20 March 1297. The emperor also gave Chinese titles to the brothers as subordinates of Kyawswa. The brothers resented the new arrangement as it directly reduced their power. On 17 December 1297, the three brothers overthrew Kyawswa, and founded the Myinsaing Kingdom. The dethronement forced the Mongol government to intervene again, leading to the second Mongol invasion of Burma . The invasion failed. Two years later, on 4 April 1303, the Mongols abolished the province of Zhengmian , evacuated Tagaung, and returned to Yunnan.
