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.

[Q]: Passage: Crimean Khan Haji Giray, learning of the defeat of the Budjak Tatars gathered 10,000-12,000 men and went against Kunitsky. At the end of December Kunitsky with 10,000-12,000 Cossacks and Moldavians left Budjak and began to cross the Prut River near the village of Tobak, not far from the town of Reni, Ukraine. Here on 30 December they were suddenly attacked by Tatar cavalry under Khan Haji Giray. Kunitsky built a fortified camp and successfully repelled the Tatar attacks. On the night of 3 to 4 January 1684 the Moldavian allies betrayed the Cossacks and left the Cossack camp. In this situation Kunitsky with the Cossack cavalry  broke through the enemy ring and crossed the Prut. The Cossack infantry  under Andrey Mogila also broke out and crossed the Prut near Boyanova, but suffered heavy losses. By 10 January only five thousand Cossacks reached Jassy.
[A]: How many days after the Cossacks and Moldavians were attacked by Tatar calalry under Khan Haji Giray did the Moldavian allies betray the Cossacks?


[Q]: Passage: Three star systems appear to have exoplanet. HD 9446 is a sun-like star around 171 light-years distant that has two planets of masses 0.7 and 1.8 times that of Jupiter, with orbital periods of 30 and 193 days respectively. WASP-56 is a sun-like star of spectral type G6 and apparent magnitude 11.48 with a planet 0.6 the mass of Jupiter that has a period of 4.6 days. HD 13189 is an orange giant of spectral type K2II about 2-7 times as massive as the sun with a planetary or brown dwarf companion between 8 and 20 times as massive as Jupiter, which takes 472 days to complete an orbit. It is one of the largest stars discovered to have a planetary companion.
[A]: How many of HD 9446's planetary companions are larger than Jupiter?


[Q]: Passage: When the Qing defeated Dzungar Mongols in 1759, they proclaimed that the Oirats territorial lands were absorbed into "China"  realm in a Manchu language memorial. They expounded the ideology that they were bringing together the "outer" non-Han Chinese like the Khalkha Mongols, Inner Mongols, Oirats  together with the "inner" Han Chinese, into "one family" united under the Qing state. To show that the diverse subjects of the Qing were all part of one family, the Qing used the phrase "Zhongwai yijia"  or "neiwei yijia" , to convey this idea of "unification" of the different peoples. A Manchu language version of a treaty with the Russian Empire concerning criminal jurisdiction over bandits called Qing subjects "people of the Central Kingdom ". In the Manchu official Tulisen's Manchu language account of his meeting with the Torghut leader Ayuka Khan, it was mentioned that while the Torghuts were unlike the Russians,  the  "people of the Central Kingdom"  were like the Torghuts, and the "people of the Central Kingdom" referred to the Manchus. The initial conquest of China by the Manchus was one of the most devastating wars in Chinese history. Examples of the devastation include the Yangzhou massacre; in which some 800,000 people, including women and children, were massacred. Whole provinces, such as Sichuan and Jiangnan, were thoroughly devastated and depopulated  by the Manchu conquest, which killed an estimated 25 million people. Some scholars estimate that the Chinese economy did not the regain the level reached in the late Ming until 1750, a century after the foundation of the Qing dynasty. According to economic historian Robert Allen, family income in the Yangtze delta, China's richest province, was actually below Ming levels in 1820 .
[A]:
How many more people were killed as a result of the devastation of Sichuan and Jiangnan than the Yangzhou massacre?
