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.

Example Input: Passage: Before 1906, when the Senussi became involved in resistance against the French, they had been a "relatively peaceful religious sect of the Sahara Desert, opposed to fanaticism". In the Italo-Turkish War  Italian forces occupied enclaves along the Libyan coast and the Senussi resisted from the interior, maintaining generally friendly relations with the British in Egypt. In 1913, the Italians had been defeated at the Action of Etangi but in 1914 Italian reinforcements led to a revival and by January the Senussi were in south-eastern Cyrenaica. The Senussi had about 10,000 men armed with modern rifles, with ammunition from a factory which produced 1,000 rounds a day. Intermittent fighting continued between the Italians in fortified towns and the Senussi ranging through the desert. The British declared war on the Ottoman Empire on 5 November and the leadership of the Ottoman Empire encouraged the Senussi to attack Egypt from the west. The Ottomans wanted the Senussi to conduct operations against the rear of the defenders of the Suez Canal; the Ottomans had failed in previous attacks against British forces from Sinai in the east and wanted them to be distracted by attacks from the opposite direction.
Example Output: How many more men did the Senussi have than ammunition that was produced per day?

Example Input: Passage: Regent Moray and his secretary John Wood tried to gain English support by producing the Casket letters in England, which were intended to incriminate Mary in the death of Lord Darnley. Moray also raised money in London by selling items from the Scottish crown jewels, including what was claimed to be a unicorn horn. Queen Elizabeth and her advisors were at first reluctant to intervene but their actions, and support of Moray, served to prevent reconciliation in Scotland. The Regent Moray was assassinated in January 1570 by a member of the Hamilton family. Elizabeth sent an army into Scotland in May 1570, which reached Glasgow, where the Queen's party were besieging Glasgow Castle. The army was commanded by the Earl of Sussex from Berwick, its leader in Scotland was William Drury, styled "Captain General." The Earl of Lennox was in their company, arriving at Edinburgh on 14 May 1570. The Marian lords abandoned their siege of Glasgow Castle before the English arrived on 18 May, and returned to their homelands, the Hamiltons to Arran and Craignethan Castle, and Drury attempted a siege of Dumbarton Castle. For Elizabeth's foreign policy this intervention had the effect of making France and Spain less likely to offer tangible pro-Marian support. After the Rising of the North and the discovery of the Ridolfi plot which further damaged Mary's reputation, Regent Mar and James Douglas, Earl of Morton were able to broker the deployment of an English army against Mary's supporters at Edinburgh Castle. The English diplomat Henry Killigrew worked on the reconciliation of the Scottish nobility at Perth in February 1572, where many promised not to support Mary as Queen. The fall of Edinburgh Castle concluded the civil war.
Example Output: How did Moray die?

Example Input: Passage: The Mongols' greatest triumph was when Kublai Khan established the Yuan dynasty in China in 1271. The Yuan dynasty created a "Han Army"  out of defected Jin troops and an army of defected Song troops called the "Newly Submitted Army" . The Mongol force which invaded southern China was far greater than the force they sent to invade the Middle East in 1256. The Yuan dynasty established the top-level government agency Bureau of Buddhist and Tibetan Affairs to govern Tibet, which was conquered by the Mongols and put under Yuan rule. The Mongols also invaded Sakhalin Island between 1264 and 1308. Likewise, Korea  became a semi-autonomous vassal state and compulsory ally of the Yuan dynasty for about 80 years. The Yuan dynasty was eventually overthrown during the Red Turban Rebellion in 1368 by the Han Chinese who gained independence and established the Ming dynasty.
Example Output:
For how many years did the Mongols invade Sakhalin Island?
