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: 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.
Example Output: How many Austrians were captured in 1598?

Example Input: Passage: Coming off their Monday night road win over the Redskins, the Eagles went home for a Week 8 NFC East duel with the New York Giants with the division lead on the line. Philadelphia came out soaring in the first quarter as fullback Leonard Weaver got a 41-yard touchdown run, followed by quarterback Donovan McNabb hooking up with tight end Brent Celek on a 17-yard touchdown pass (with a blocked PAT).  In the second quarter, the Eagles increased their lead as kicker David Akers nailed a 30-yard field goal.  The Giants would get on the board as quarterback Eli Manning found tight end Kevin Boss on an 18-yard touchdown pass, yet Philadelphia kept their momentum going as McNabb completed a 54-yard touchdown pass to wide receiver DeSean Jackson and a 23-yard touchdown pass to rookie wide receiver Jeremy Maclin. The Eagles would increase their lead in the third quarter as Akers booted a 35-yard field goal, yet New York attempted to rally as kicker Lawrence Tynes made a 42-yard field goal and running back Ahmad Bradshaw got a 1-yard touchdown run.  In the fourth quarter, Philadelphia pulled away with a 66-yard touchdown run by rookie running back LeSean McCoy. With the win, not only did the Eagles improve to 5-2, but they would take over as the leader of the NFC East.
Example Output: How many field goals did David Akers kick in the second half?
