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: On 24 August, Charles X Gustav joined Wittenberg's forces. The Polish king John II Casimir left Warsaw the same month to confront the Swedish army in the west, but after some skirmishes with the Swedish vanguard retreated southwards to Kraków. On 8 September Charles X Gustav occupied Warsaw, then turned south to confront the retreating Polish king. The kings met at the Battle of Żarnów on 16 September, which like the next encounter at the Battle of Wojnicz on 3 October was decided for Sweden. John II Casimir was exiled to Silesia while Kraków surrendered to Charles X Gustav on 19 October. On 20 October, a second treaty was ratified at Kėdainiai in the north. The Union of Kėdainiai unified Lithuania with Sweden, with Radziwiłł recognizing Charles X Gustav as Grand Duke of Lithuania. Over the following days, most of the Polish army surrendered to Sweden: on 26 October Koniecpolski surrendered with 5,385 men near Kraków, on 28 October Field Crown Hetman Stanisław Lanckoroński and Great Crown Hetman Stanisław "Rewera" Potocki surrendered with 10,000 men, and on 31 October the levy of Mazovia surrendered after the Battle of Nowy Dwór.

Answer: About how many months do these events span?


Question: Passage: With Steigerwalds departure in 1999, Mike Lange shared the broadcast booth with former Penguins defenseman Peter Taglianetti. Taglianetti, a two-time Stanley Cup winner with the team in 1991 and 1992, remained in the position for one season before being replaced by Ed Olczyk. Lange and Olczyk were broadcast partners from 2000 until 2003, when Olczyk left the booth to become the 18th head coach in Penguins history that had become upon due to the firing of previous Head Coach Rick Kehoe after the 2002–03 season. With Olczyks vacancy, the Penguins hired Bob Errey as their new color commentator for the start of the 2003–04 season (a position that he continues to hold as of the start of the 2012–13 season. Lange and Errey remained in the booth until 2005–06. After 26 seasons in the television broadcast booth, Mike Lange was not retained by FSN Pittsburgh. Instead, he was replaced by former broadcast partner Paul Steigerwald, who remained the TV play-by-play broadcaster for the team until the 2016–17 season. Lange returned to the radio broadcast booth and currently holds the position of radio play-by-play announcer, the same position he had held with the team in the mid-1970s. Following the 2016–17 season, Steigerwald moved back to the Penguins front office and NHL Network (U.S. TV network) personality Steve Mears was hired as the new television play-by-play announcer starting with the 2017–18 season.

Answer: How many year was Lange and Olczyk broadcast partners?


Question: Passage: The US had a gold stock of 1.9 million ounces (59 t) in 1862. Stocks rose to 2.6 million ounces (81 t) in 1866, declined in 1875 to 1.6 million ounces (50 t) and rose to 2.5 million ounces (78 t) in 1878. Net exports did not mirror that pattern. In the decade before the Civil War net exports were roughly constant; postwar they varied erratically around pre-war levels, but fell significantly in 1877 and became negative in 1878 and 1879. The net import of gold meant that the foreign demand for American currency to purchase goods, services, and investments exceeded the corresponding American demands for foreign currencies. In the final years of the greenback period (1862-1879), gold production increased while gold exports decreased.  The decrease in gold exports was considered by some to be a result of changing monetary conditions. The demands for gold during this period were as a speculative vehicle, and for its primary use in the foreign exchange markets financing international trade. The major effect of the increase in gold demand by the public and Treasury was to reduce exports of gold and increase the Greenback price of gold relative to purchasing power.

Answer:
Was the gold stock of the United States higher in 1862 or 1866?
