TASK DEFINITION: This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning). 
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.
PROBLEM: Passage: During the early months of World War I, Kars was a key military objective for the Ottoman army. Ismail Enver who pushed the Ottoman Empire into World War I, needed a victory against the Russians to defend his position. He collected an army on the eastern border. The army was badly defeated under Enver's command at the Battle of Sarikamish January 2, 1915 against Nikolai Nikolaevich Yudenich. This defeat was more due to the winter weather and bad planning, given the fact that Russians were actually preparing to evacuate Kars. With the loss of the eastern army, Ottoman defenses crumbled with further small battles and the Russian army succeeded in advancing as far west as Erzincan. The collapse of the Russian army after the 1917 revolution left only thinly spread Armenian units to resist the inevitable Ottoman counter-attack. Before the end of World War I in 1918, the Ottoman army reformed with what was left from the middle-east branch and tried to build a line between whatever seemed to be left on their east border. The newly declared First Republic of Armenia captured Kars in April 1918, which was eventually handed back by the future Soviet administration. That same year in March, the Baku Commune was established in the Azerbaijan Democratic Republic. The commune later became the Centrocaspian Dictatorship, in turn conquered by the Islamic Army of the Caucasus, then shortly by the Triple Entente and finally the Bolsheviks. Defeat on other fronts caused the Ottoman Empire to surrender and withdraw forces. Both the Armenian and Azerbaijani Republics ended up being part of the Soviet Union in 1920.

SOLUTION: How many groups conquered the Centrocaspian Dictatorship?

PROBLEM: Passage: The disintegration of Russia offered Finns an historic opportunity to gain national independence. After the October Revolution, the conservatives were eager for secession from Russia in order to control the left and minimise the influence of the Bolsheviks. The socialists were skeptical about sovereignty under conservative rule, but they feared a loss of support among nationalistic workers, particularly after having promised increased national liberty through the "Law of Supreme Power". Eventually, both political factions supported an independent Finland, despite strong disagreement over the composition of the nation's leadership. Nationalism had become a "civic religion" in Finland by the end of nineteenth century, but the goal during the general strike of 1905 was a return to the autonomy of 1809-1898, not full independence. In comparison to the unitary Swedish regime, the domestic power of Finns had increased under the less uniform Russian rule. Economically, the Grand Duchy of Finland benefited from having an independent domestic state budget, a central bank with national currency, the markka , and customs organisation and the industrial progress of 1860-1916. The economy was dependent on the huge Russian market and separation would disrupt the profitable Finnish financial zone. The economic collapse of Russia and the power struggle of the Finnish state in 1917 were among the key factors that brought sovereignty to the fore in Finland.

SOLUTION: Finland was supported by whom?

PROBLEM: Passage: Coming off their divisional road win over the Lions, the Vikings played their Week 3 home opener against the San Francisco 49ers. Minnesota opened in the first quarter with quarterback Brett Favre's 30-yard touchdown pass to wide receiver Sidney Rice. The Vikings added onto their lead in the second quarter with kicker Ryan Longwell's 40-yard field goal, but the 49ers answered with quarterback Shaun Hill's 5-yard touchdown pass to tight end Vernon Davis. Minnesota came back with Longwell's 52-yard field goal, but San Francisco took the lead prior to halftime as cornerback Nate Clements returned a blocked field goal 59 yards for a touchdown. The 49ers increased their lead in the second half with kicker Joe Nedney's 37-yard field goal, but the Vikings immediately responded with rookie wide receiver Percy Harvin returning a kickoff 101 yards for a touchdown. In the fourth quarter, San Francisco got the lead again with Hill hooking up with Davis on a 20-yard touchdown pass. Afterwards, Minnesota came up with a dramatic win as Favre completed a game-winning 32-yard touchdown pass to wide receiver Greg Lewis with 2 seconds remaining in the game. The pass was later awarded an ESPY for "Best Play". The game was also voted as the best game of the regular season by voters on NFL.com.

SOLUTION:
How long was the longest field goal of the game?
