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: Anaukpetlun then brought trans-Salween Shan states under his rule in the 1620s. In February 1622, his forces  took Kengtung, which had been held by an ally of Lan Xang, after a fierce battle. Reinforced Burmese armies led by the king's brothers Thalun and Minye Kyawswa II invaded the Chinese Shan states in present-day southern Yunnan in May 1622. For the next 20 months, Burmese forces chased Kenghung troops. Finally in January 1624, Kenghung and Kengyun both surrendered. Kengyun promptly rebelled the following year but it was put down in December 1626 by the king's brothers. By then, Nyaungyan and Anaukpetlun had restored much of Bayinnaung's empire. Only Siam and Lan Xang remained outside the Restored Toungoo Empire. But the Burmese would not overstretch again. They would not launch major invasions against these neighbours until the 1760s.

SOLUTION: Anaukpetlun's forces took Kengtung how many years before Kenghung and Kengyun both surrendered?

PROBLEM: Passage: A second expedition had to be conducted to bring Lan Na under control again. The Siamese army invaded Chiang Mai, catching the Burmese command completely off guard. The Siamese captured Chiang Mai on 10 February 1663, and drove back Burmese forces that arrived belatedly at Sai Yok. In November 1663, the Siamese then led an army of 60,000 in an invasion of Burma, capturing Martaban, Moulmein, Syriam, Rangoon, Pegu, and then laid siege to Pagan in 1664. Burmese defences withstood several Siamese onslaughts until May 1664 before the rainy season arrived, after "causing many casualties in dead and wounded and capturing many prisoners of war", the Siamese retreated.:220-239 Meanwhile, the Siamese garrison at Chiang Mai was holed up in a deserted city, and its troops were constantly ambushed by resistance forces whenever they ventured out of the city. In late November 1664, the Siamese evacuated Chiang Mai, and returned.

SOLUTION:
How many areas in Burma were captured by the Siamese in 1663?
