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: Mount Vesuvius has erupted many times. The famous eruption in AD 79 was preceded by numerous others in prehistory, including at least three significantly larger ones, the best known being the Avellino eruption around 1800 BC which engulfed several Bronze Age settlements. Since AD 79, the volcano has also erupted repeatedly, in 172, 203, 222, possibly in 303, 379, 472, 512, 536, 685, 787, around 860, around 900, 968, 991, 999, 1006, 1037, 1049, around 1073, 1139, 1150, and there may have been eruptions in 1270, 1347, and 1500. The volcano erupted again in 1631, six times in the 18th century (including 1779 and 1794), eight times in the 19th century (notably in 1872), and in 1906, 1929 and 1944. There have been no eruptions since 1944, and none of the eruptions after AD 79 were as large or destructive as the Pompeian one. Vesuvius entered a new phase in December 1631, when a major eruption buried many villages under lava flows, killing around 3,000 people. Torrents of lahar were also created, adding to the devastation. Activity thereafter became almost continuous, with relatively severe eruptions occurring in 1660, 1682, 1694, 1698, 1707, 1737, 1760, 1767, 1779, 1794, 1822, 1834, 1839, 1850, 1855, 1861, 1868, 1872, 1906, 1926, 1929, and 1944.

SOLUTION: Did Mount Vesuvius erupt more times in the 18th or 19th centuries?

PROBLEM: Passage: Following a preliminary bombardment, the battle for Cebu City began on March 26, 1945, when the Allies launched Operation Victor II. Staging out of Leyte, where they had conducted rehearsal landings two days earlier, a large flotilla of cruisers and destroyers from the United States Seventh Fleet's Task Force 74 escorted the Cebu Attack Group to the island. Under the leadership of Major General William H. Arnold, the forces assigned to the operation consisted of the Americal Division's 132nd and 182nd Infantry Regiments, totaling about 5,000 men, were landed on Cebu island at Talisay Beach, 4 miles  southwest of Cebu City. The 182nd came ashore southwest of the city, while the 132nd landed at a wide gravel beach to the northeast opposite a palm grove. Meeting no Japanese opposition, the U.S. forces nevertheless suffered heavily from mines and booby traps as they crossed the beach.

SOLUTION: How many infantry regiments did Major General William H. Arnold lead?

PROBLEM: Passage: In December 1340, the payment of the pledge was due. Since this did not happen, the pledged lands fell to Mecklenburg. However, no investiture of the Prince of Mecklenburg was made by the Danish king Valdemar IV Atterdag. In autumn 1342, the Pomeranian Marshal, Wedego Bugenhagen, gained control of Grimmen. In September 1343, the Mecklenburg army under Albert II succeeded in storming the town. Thanks to mediation by the towns of Stralsund and Greifswald, a ceasefire was agreed in October 1343. But the agreed arbitration never took place. Valdemar IV Atterdag, as the former feudal lord avoided making a decision, as he feared that the losing party would desert him. Because the sons of Vartislav IV of Pomerania-Wolgast could not redeem the pledged estates, but continued to claim them back, there was renewed fighting with Mecklenburg in 1351. With the support of Barnim III of Pomerania-Stettin, an army led by Baron Klaus Hahn inflicted a devastating defeat on Mecklenburg on 25 October 1351 at the Schopendamm near Loitz. Amongst the fallen on the Pomeranian side, was Count John IV the Younger of Gützkow. As the Gützkow count had no male offspring, the county of Gützkow was later seized by Barnim III.

SOLUTION:
How many months after the Mecklenburg army under Albert II stormed Grimmen was a ceasefire agreed?
