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: After the war, the Paris Peace Conference imposed a series of peace treaties on the Central Powers officially ending the war. The 1919 Treaty of Versailles dealt with Germany and, building on Wilson's 14th point, brought into being the League of Nations on 28 June 1919. The Central Powers had to acknowledge responsibility for "all the loss and damage to which the Allied and Associated Governments and their nationals have been subjected as a consequence of the war imposed upon them by" their aggression. In the Treaty of Versailles, this statement was Article 231. This article became known as the War Guilt clause as the majority of Germans felt humiliated and resentful. Overall the Germans felt they had been unjustly dealt with by what they called the "diktat of Versailles". German historian Hagen Schulze said the Treaty placed Germany "under legal sanctions, deprived of military power, economically ruined, and politically humiliated." Belgian historian Laurence Van Ypersele emphasises the central role played by memory of the war and the Versailles Treaty in German politics in the 1920s and 1930s:.
[EX A]: About how many years was the central role played by memory of the war and the Versailles Treaty?

[EX Q]: Passage: In week 11, the Lions traveled to Arlington, Texas to play the Dallas Cowboys. The only score of the first quarter was a 1-yard TD catch by Dez Bryant of the Cowboys. In the second quarter the Lions got on the board with a 47-yard field goal, and took the lead with a 9-yard TD catch by Nate Burleson. After halftime, Leonard Davis of the Cowboys committed an offensive holding penalty in his own end zone, giving the Lions a safety. The Cowboys took the lead though with a 97-yard punt return by Bryan McCann, and added to it with a 3-yard catch by Miles Austin. The Lions responded with a 14-yard catch by Calvin Johnson. In the 4th quarter, Miles Austin caught another TD, this time from 4 yards out. Later, Jon Kitna sealed the Cowboys win with a 29-yard TD run. With the loss, not only did the Lions fall to 2-8, but they added to their already record setting 26 game road losing streak.
[EX A]: How many yards did Bryant catch?

[EX Q]: Passage: The last accurate census of the population of Cyprus with regard to its ethnic breakdown was carried out in 1960; it recorded 3,628 Armenians in Cyprus . In 1978 and 1987 the Armenian Prelature recorded the Armenian population of Cyprus, which was 1,787 and 2,742, respectively . Since then, their number has increased; currently, about 3,500 Armenians live in Cyprus: 65% live in the capital, Nicosia, 20% in Larnaca, 10% in Limassol and 5% in Paphos and some villages. Over 95% of the Armenian population of Cyprus speak Armenian and are Armenian Orthodox ; some 5% belong either to the Armenian Evangelical Church, the Armenian Catholic Church, the Latin Church, the Greek Orthodox Church, the Anglican Church, the Plymouth Brethren Church, the Seventh-day Adventist Church or they are Jehovah's Witnesses. About 1,000 out of the 3,500 Armenians who live in Cyprus hail from Armenia, Lebanon, Syria, Russia, Georgia, Persia, Greece, Iraq, Ethiopia, Turkey and Kuwait. Most of the first wave of Armenians from Armenia who arrived in Cyprus from 1988 onwards were in fact the Armenian-Cypriots and their descendants who emigrated to Armenia between 1962-1964, as part of the nerkaght  Panarmenian movement.
