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.

Q: Passage: The Dano-Hanseatic War from 1426-1435  was an armed trade conflict between the Danish dominated Kalmar Union  and the German Hanseatic League  led by the Free City of Lübeck. When Danish king Eric opened the Baltic trade routes for Dutch ships and introduced a new toll for all foreign ships passing the Øresund , six Hanseatic cities  declared war, put a naval blockade on Scandinavian harbours and allied with Eric's enemy Henry IV, count of Holstein. Therefore the war was intensively linked with the Dutch-Hanseatic War , the Kalmar War with Holstein  and the Swedish revolt . After years of changing fortune in warfare Rostock and Stralsund signed a separate peace agreement in 1430. Lübeck, Hamburg, Wismar and Lüneburg, however, continued the war and assisted Holstein to conquer Flensburg in 1431. Thereafter they agreed an armistice in 1432 and started peace negotiations. Meanwhile an anti-Danish revolt broke out in Sweden . In 1434 Eric had to agree an armistice with the Swedes, too. In April 1435 he signed the peace of Vordingborg with the Hanseatic League and Holstein, followed by the peace of Stockholm with Sweden a few months later the same year. The Hanseatic cities were excepted from the Sound Dues but they had to accept Dutch competition in the Baltic trade. The Danish Duchy of Schleswig was ceded to the count of Holstein. Sweden's autonomous rights and privileges were extended. These peace agreements weakened Eric's position dramatically, and in 1439 he got dethroned by Danish, Swedish and Norwegian Privy Councils.

A: Around how many months do these events span?

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 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.

A: How long after being attacked did Heydrich die?
