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: Hoping to beat the defending Super Bowl champs, the Ravens returned home. New Orleans struck first with an 18-yard pass from Drew Brees to Jimmy Graham, but Baltimore quickly answered with Flacco throwing a 34-yard pass to Ed Dickson. The Ravens then followed with two touchdowns, both by Ray Rice, one rushing (10yards) and one passing (17yards), to bring the score up 21-7. At the close of the half, the Saints scored on a 1-yard pass to Graham to bring the halftime score to 21-14. The Saints kicked a field goal to enter the third quarter to make it 21-17, but the Ravens quickly answered that with a field goal to make it 24-17. The Saints tied it in the fourth quarter on a 15-yard touchdown pass to Lance Moore in the corner of the end zone, a play that was challenged by Baltimore but not overturned. The Ravens managed to get ahead with a Billy Cundiff field goal with 10:03 remaining 27-24.The Saints had the ball in the final minutes backed up near their own end zone when Drew Brees threw an interception to Cory Redding to give Baltimore a chance to run off the clock. Though there was not enough time to run off the entire clock, Baltimore managed to leave just 9seconds as they kicked a field goal to make it 30-24. The Saints had one last chance on their kickoff return in which they pitched it around in hopes of a touchdown, but they were stopped. They were also called for a moot penalty for a forward pass that would have rendered any drive at this point null. Overall, the game was highlighted by Ray Rice's 153yards rushing and two touchdowns, Billy Cundiff's two field goals, and the Redding interception that virtually ended the game. With the win, the Ravens went to 10-4, nearly clinching a playoff berth.

Answer: How many first half touchdowns were scored?

Question: Passage: Anaukpetlun then brought trans-Salween Shan states under his rule in the 1620s. In February 1622, his forces took Kengtung, which had been held by an ally of Lan Xang, after a fierce battle. Reinforced Burmese armies led by the king's brothers Thalun and Minye Kyawswa II invaded the Chinese Shan states in present-day southern Yunnan in May 1622. For the next 20 months, Burmese forces chased Kenghung troops. Finally in January 1624, Kenghung and Kengyun both surrendered. Kengyun promptly rebelled the following year but it was put down in December 1626 by the king's brothers. By then, Nyaungyan and Anaukpetlun had restored much of Bayinnaung's empire. Only Siam and Lan Xang remained outside the Restored Toungoo Empire. But the Burmese would not overstretch again. They would not launch major invasions against these neighbours until the 1760s.

Answer: Anaukpetlun's forces took Kengtung how many years before Kenghung and Kengyun both surrendered?

Question: Passage: Like Sweden, John II Casimir was also looking for allies to break the deadlock of the war. On 1 December 1656, he signed an alliance with Ferdinand III of Habsburg in Vienna, essentially a declaration of Ferdinand III's intend to mediate a peace rather than provide military aid, which did not come into effect until Ferdinand's death on 2 April 1657. The treaty was however renewed and amended on 27 May by Ferdinand's successor Leopold I of Habsburg, who agreed in Vienna to provide John II Casimir with 12,000 troops maintained at Polish expense; in return, Leopold received Krakow and Posen in pawn. Receiving the news, Frederick III of Denmark promptly declared war on Sweden, and by June the Austrian army entered the Polish-Lithuanian Commonwealth from the south, immediately stabilizing the situation in southern Poland, while Denmark attacked Swedish Bremen-Verden and turned to Jamtland and Vastergotland in July. When Charles X Gustav left the Commonwealth and headed westwards for an anti-Danish counterstrike, the Swedish-Brandenburgian-Transylvanian alliance broke apart. Rakoczi of Transylvania was unable to withstand the combined Austrian and Polish-Lithuanian forces without Swedish support, and after a pursuit into Ukraine he was encircled and forced to capitulate, with the rest of the Transylvanian army defeated by the Tartars. Brandenburg changed sides in return for Polish withdrawal of claims to Ducal Prussia, declaring Frederick William the sole sovereign in the Duchy with the treaties of Wehlau on 19 September and Bromberg on 6 November. In addition, the aforementioned treaties secured Brandenburg the Lands of Lauenburg and Butow at the border of Brandenburgian Pomerania, while the Bishopric of Ermeland was returned to Poland.

Answer:
About how many months do these events span for?
