instruction:
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.
question:
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.
answer:
How many groups conquered the Centrocaspian Dictatorship?


question:
Passage: Forecasting airline interest in larger-capacity models, Boeing announced the stretched 767-300 in 1983 and the extended-range 767-300ER in 1984. Both models offered a 20 percent passenger capacity increase, while the extended-range version was capable of operating flights up to . Japan Airlines placed the first order for the 767-300 in September 1983. Following its first flight on January 30, 1986, the type entered service with Japan Airlines on October 20, 1986. The 767-300ER completed its first flight on December 9, 1986, but it was not until March 1987 that the first firm order, from American Airlines, was placed. The type entered service with American Airlines on March 3, 1988. The 767-300 and 767-300ER gained popularity after entering service, and came to account for approximately two-thirds of all 767s sold.
answer:
How many months after the first flight of the 767-300 was the first flight of the 767-300ER?


question:
Passage: The Chiefs returned home to host the Steelers in an attempt to create the biggest upset of the week and get their first back-to-back wins since 2007.  Optimism grew quickly as Jamaal Charles ran the opening kick 97 yards for a touchdown, starting the game with a 7-0 Chiefs lead. The Steelers dominated the rest of the first half with 20:45 time of possession, going into halftime with a 17-7 lead.  The Chiefs' defense began to pressure Ben Roethlisberger in the third quarter, forcing two interceptions (both by Andy Studebaker in his first NFL start).  By the fourth quarter, the Chiefs tied the game up at 17-17.  The fourth quarter resulted in a touchdown each, sending the game into overtime. The Steelers won the toss in overtime, but failed to get within field goal range.  Of note, Roethlisberger suffered a knee to the head concussion and was replaced by Charlie Batch.  The Chiefs took over at the 20 and, after a 61-yard catch and run by Chris Chambers, Ryan Succop kicked the winning 22-yard field goal.  With the win, the Chiefs improved to 3-7 and snapped a 10-game home losing streak, the longest in team history.
