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: After a humiliating defeat a week before against the Dolphins, the Texans' defense looked much better holding the Titans to just a field goal in the 1st quarter. Houston's offense scored a touchdown early in the 2nd quarter to take a 7-3 lead. On the ensuing kickoff, Tennessee's Bishop Sankey fumbled the ball with Kurtis Drummond recovering it for Houston. The Texans settled for 3 off the turnover with a 38-yard field goal from Nick Novak. Late in the 3rd quarter Brian Hoyer connected with former Titan Nate Washington for a 42-yard touchdown pass, extending the Texans' lead to 17-6 with Novak making the PAT. To start out the 4th quarter, Kevin Johnson got his first career interception by picking off a Zach Mettenberger pass. Houston failed to capitalized on the turnover, however Tennessee turned the ball over after a J. J. Watt sack, giving the Texans the ball at the Titans' 10-yard line. The Texans scored another 3 points off of the turnover, with Novak making a 24-yard field goal. Houston defeated Tennessee 20-6 and improved to 3-5. Watt, Whitney Mercilus and Jared Crick combined for a total of 6 sacks for the Texans' defense.
answer:
How many TD were scored in the first quarter?


question:
Passage: Still searching for their first win of the year, the Chiefs went home to play a Week 3 interconference duel with the Minnesota Vikings.  Very much a tale of two halves, Minnesota dominated through most of the first half.  Larry Johnson of the Chiefs was ineffective against the Minnesota defense while Adrian Peterson rushed for 102&#160;yards and a touchdown (mostly in the first half).  After making changes during halftime, the Chiefs returned with a passing game and an amped up defense.  The Chiefs' Jared Allen, back from suspension, led the defense with eight tackles, two sacks, and a forced fumble, shutting down the Vikings' offense.  Chiefs' rookie Dwayne Bowe, with one reception coming into the game, benefited from the second half passing game with five receptions, including a touchdown.
answer:

What was the Chiefs second half game plan?
