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.

[EX Q]: Passage: In 2007-2008, Sun posted revenue of $13.8 billion and had $2 billion in cash. First-quarter 2008 losses were $1.68 billion; revenue fell 7% to $12.99 billion. Suns stock lost 80% of its value November 2007 to November 2008, reducing the companys market value to $3 billion. With falling sales to large corporate clients, Sun announced plans to lay off 5,000 to 6,000 workers, or 15-18% of its work force. It expected to save $700 million to $800 million a year as a result of the moves, while also taking up to $600 million in charges.
[EX A]: How many billion did Sun's revenue fall by in the first quarter of 2008?

[EX Q]: Passage: He was however forced to fall back across the Danube, and the Ottomans in turn led a massive counter-offensive  which aimed to not only take back their recently captured possessions but also conquer Wallachia once and for all. The push was initially successful, managing to capture not only Giurgiu but also Bucharest and Târgovişte, in spite of meeting fierce opposition at Călugăreni . At this point the Ottoman command grew complacent and stopped pursuing the retreating Wallachian army, focusing instead on fortifying Târgovişte and Bucharest and considering their task all but done. Michael had to wait almost two months for aid from his allies to arrive, but when it did his counter-offensive took the Ottomans by surprise, managing to sweep through the Ottoman defences on three successive battlefields, at Târgovişte , Bucharest , and Giurgiu . The Battle of Giurgiu in particular was devastating for the Ottoman forces, which had to retreat across the Danube in disarray. The war between Wallachia and the Ottomans continued until late 1599, when Michael was unable to continue the war due to poor support from his allies. The turning point of the war was the Battle of Mezőkeresztes, which took place in the territory of Hungary on October 24-26, 1596. The combined Habsburg-Transylvanian force of 45-50,000 troops was defeated by the Ottoman army. The battle turned when Christian soldiers, thinking they had won the battle, stopped fighting in order to plunder the Ottoman camp. Despite this victory, the Ottomans realized for the first time the superiority of Western military equipment over Ottoman weapons. This battle was the first significant military encounter in Central-Europe between a large Christian army and the Ottoman Turkish Army after the Battle of Mohács. Nevertheless, Austrians recaptured Győr and Komarom in 1598.
[EX A]: How many Austrians were captured in 1598?

[EX Q]: Passage: A single soldier arriving in Mexico in 1520 was carrying smallpox and thus initiated the devastating plagues that swept through the native populations of the Americas. The European diseases that ravaged the indigenous inhabitants of the Americas also severely affected the various Maya groups of Petén. It is estimated that there were approximately 30,000 Ch'ol and Ch'olti' Maya in western Petén at the start of the 16th century. Between 1559 and 1721 they were devastated by a combination of disease, war and enforced relocations. When Nojpetén fell in 1696 there were approximately 60,000 Maya living around Lake Petén Itzá, including a considerable number of refugees from other areas. It is estimated that 88% of the inhabitants died during the first decade of colonial rule because of disease and war. Although disease was responsible for the majority of deaths, internecine warfare between rival Maya groups and Spanish expeditions also took their toll.
[EX A]:
How many different types of people did the plagues affect counting the indigenous inhabitants in the Americas?
