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: 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.
[EX A]: Around how many months do these events span?

[EX Q]: Passage: He married Marie Armstrong (1892-1956), a gentile, in 1915, when he was twenty-one years of age, and they had a daughter, Edwina, who became actress Edwina Armstrong (1916-1991). He later met Rose Caylor, a writer, and together they left Chicago (and his family) in 1924, moving to New York. He was divorced from Armstrong in 1925. He married Caylor that same year, and they remained married until Hechts death in 1964. On July 30th, 1943 Ben and Rose had a daughter, Jenny Hecht, who became an actress at the age of 8, and first appeared on The Ed Sullivan Show playing the role of Helen Hayes in "The Helen Hayes Story," 1951. Jennys next appearance was in the movie "Actors and Sin," 1952. Jenny also appeared in the movie "Apres la Passion selon Sade," 1968. Jenny appeared on Broadway at the age of 9 in "MID-SUMMER," 1953-1954, "SIMONE," 1959, and in "THE PLOUGH AND THE STARS," 1960. Jenny performed with The Living Theater, 1963-1970. Jenny also had several television appearances, including "Three Empty Rooms," 1953, "Climax," 1958, "Wagon Train," 1958, and "The FBI," 1971. Jennys last appearance was in the movie "The Jesus Trip," 1971. It is not known if it was accidental or intentional, but shortly after filming of "The Jesus Trip" was completed Jenny died of a drug overdose on March 25, 1971 at the age of 27. A play about Jennys brief life, The Screenwriters Daughter, was staged in London in October 2015.
[EX A]: Did Jenny appear on The Ed Sullivan Show or on broadway first?

[EX Q]: Passage: Documentation of deaths was poor during the Great Frost. Cemeteries provide fragmentary information, e.g., during February and March 1740, 47 children were buried in St. Catherine's parish. The normal death rate tripled in January and February 1740, and burials averaged out about 50% higher during the twenty-one-month crisis than for the years 1737-1739, according to Dickson. Summing up all his sources, Dickson suggests two estimates:1) that 38% of the Irish population died during the crisis, and2) that between 13-20% excess mortality occurred for 1740-1741. Based on contemporary accounts and burial parish records, famine-related deaths may have totaled 300,000-480,000 in Ireland, with rates highest in the south and east of the country. This was a proportionately greater toll than during the most severe years of the Great Famine .  That famine, however, was unique in "cause, scale and timing," persisting over several years. The majority of the deaths occurred amongst the lower classes, with the poorest third of the population gaining all their nutrition from potatoes alone, the crop which the blight affected. Therefore, when the potatoes blight occurred these people were left with practically no means of sustenance.
[EX A]:
Approximately how many years did the crisis of the Great Frost last?
