TASK DEFINITION: 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.
PROBLEM: 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 Jože Plečnik. In this period the St Vitus Cathedral was finished .  Renovations continued in 1936 under Plečnik's successor Pavel Janák. 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 Plečnik, president Václav Havel commissioned Bořek Šípek to be the architect of post-communism Prague Castle's necessary improvements, in particular of the facelift of the castle's gallery of paintings.

SOLUTION: How long after being attacked did Heydrich die?

PROBLEM: Passage: The Turkish-Armenian war, known in Turkey as the Eastern Operation or Eastern Front  of the Turkish War of Independence, refers to a conflict in the autumn of 1920 between the First Republic of Armenia and the Turkish nationalists, following the signing of the Treaty of Sèvres. After an initial Armenian occupation of what is now eastern Turkey, the army of the Turkish National Movement under Kâzım Karabekir reversed the Armenian gains and further invaded and defeated Armenia, also recapturing territory which the Ottoman Empire had lost to the Russian Empire in 1855 and 1878. The Turkish military victory was followed by Soviet Russia's occupation and sovietization of Armenia. The Treaty of Moscow  between Soviet Russia and the Grand National Assembly of Turkey and the related Treaty of Kars  confirmed the territorial gains made by Karabekir and established the modern Turkish-Armenian border. Armenia had territorial disputes with the Ottoman Empire. The Ottomans had tried to move the Armenians during the Armenian Genocide and occupied the South Caucasus during Summer 1918. Armenia resisted until the Allied forces won WWI. The Ottomans maintained their troops along their territorial gains until Spring 1919.

SOLUTION: For what time span was the Ottoman Empire able to maintain the territorial gains they won from Armenia?

PROBLEM: Passage: Historically, the first official plan for the creation of Cossack formations as a border service was brought to the State Council of the Grand Duchy of Lithuania in 1524 by Semen Polozovic and Kristof Kmitic. However, due to the lack of funds, the idea was not realized. The starosta of Cherkasy, Ostap Dashkevych, revived the idea at the 1533 council in Piotrków Trybunalski. Dashkevych tried to show that in order to protect the borders beyond the Dnieper it would be necessary to maintain an army of 2,000 soldiers and several hundred cavalrymen. He pointed out the importance of establishing forts on the river's islands to keep Tatar raids in check. On July 21, 1541 the King of Poland, Sigismund I the Old, issued an edict to the starosta of Cherkasy, Andrei Glebovich Pronsky , in which he strictly warned Pronsky to control the Cossack raids against Tatar uluses. With the start of the Livonian War in the 16th century, the voivode of Kiev, Konstanty Wasyl Ostrogski, and the starosta of Cherkasy, Alexander Wisnowecki, recruited Cossacks to their armies, while in 1568 King Sigismund II Augustus sent a proposition to the Zaporizhian Sich to join his foreign campaign and sign up for royal service. Sigismund II Augustus decreed the formation of registered Cossacks on June 5, 1572 when the King confirmed the orders of Great Crown Hetman Jerzy Jazłowiecki, the voivode of Podole and Ruthenia, for state service. The first Hetman of the Registered Cossacks and court marshal was Jan Badowski. The registered Cossacks were the only military Cossack formation recognized by the Polish-Lithuanian Commonwealth.

SOLUTION:
How many people brought the idea of the creation of Cossack formations as a border service was brought to the State Council ?
