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 1918, the castle became the seat of the president of the new Czechoslovak Republic, T.G. Masaryk. The New Royal Palace and the gardens were renovated by Slovenian architect Joze Plecnik. In this period the St Vitus Cathedral was finished . Renovations continued in 1936 under Plecnik's successor Pavel Janak. On March 15, 1939, shortly after the Nazi Germany forced Czech President Emil Hacha to hand his nation over to the Germans, Adolf Hitler spent a night in the Prague Castle, "proudly surveying his new possession." During the Nazi occupation of Czechoslovakia in World War II, Prague Castle became the headquarters of Reinhard Heydrich, the Reich Protector of Bohemia and Moravia. According to a popular rumor, he is said to have placed the Bohemian crown on his head; old legends say a usurper who places the crown on his head is doomed to die within a year. Less than a year after assuming power, on May 27, 1942, Heydrich was attacked during Operation Anthropoid, by British-trained Slovak and Czech soldiers while on his way to the Castle, and died of his wounds - which became infected - a week later. Klaus, his firstborn son, died the next year in a traffic accident, also in line with the legend. After the liberation of Czechoslovakia and the coup in 1948, the Castle housed the offices of the communist Czechoslovak government. After Czechoslovakia split into the Czech Republic and Slovakia, the castle became the seat of the Head of State of the new Czech Republic. Similar to what Masaryk did with Plecnik, president Vaclav Havel commissioned Borek Sipek to be the architect of post-communism Prague Castle's necessary improvements, in particular of the facelift of the castle's gallery of paintings.
[EX A]: How long after being attacked did Heydrich die?

[EX Q]: Passage: On the morning of 29 June, Skanderbeg arranged his army for battle. Apart from the 3,000 warriors hidden behind the Ottoman army, Skanderbeg left another reserve force of 3,000 under the command of Vrana Konti. The Albanian army was positioned in a crescent shape curving inwards. They were divided into three groups, each composed of 3,000 men.They were all placed at the bottom of a hill, with the intention of luring the Ottoman cavalry-based army into a downhill charge. The Albanian left wing was commanded by Tanush Thopia with 1,500 horsemen and an equal number of infantrymen. On the right wing, Skanderbeg placed Moisi Golemi in the same manner as Thopia. In front of the wings, foot archers were placed to lure the Ottomans in. In the center, there were 3,000 men under the command of Skanderbeg and Ajdin Muzaka. One-thousand horsemen were placed in front of the main division with orders to blunt the initial Turkish cavalry charge. An equal number of archers, trained to accompany the horses, was placed next to these horsemen. The main body of infantry, commanded by Ajdin Muzaka, was placed behind the archers.
[EX A]: How many archers were next to the one-thousand horsemen?

[EX Q]: Passage: The share of value added by the cotton textile industry in Britain was 2.6% in 1760, 17% in 1801 and 22.4% in 1831. Value added by the British woollen industry was 14.1% in 1801. Cotton factories in Britain numbered approximately 900 in 1797. In 1760 approximately one-third of cotton cloth manufactured in Britain was exported, rising to two-thirds by 1800. In 1781 cotton spun amounted to 5.1 million pounds, which increased to 56 million pounds by 1800. In 1800 less than 0.1% of world cotton cloth was produced on machinery invented in Britain. In 1788 there were 50,000 spindles in Britain, rising to 7 million over the next 30 years.
[EX A]:
How many million pounds did the cottun spun increase between 1781 and 1800?
