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.

Question: 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:.

Answer: About how many years was the central role played by memory of the war and the Versailles Treaty?


Question: Passage: The 5 October 1910 revolution was the overthrow of the centuries-old Portuguese Monarchy and its replacement by the Portuguese Republic. It was the result of a coup d'état organized by the Portuguese Republican Party. By 1910, the Kingdom of Portugal was in deep crisis: British pressure on Portugal's colonies, the royal family's expenses, the assassination of the King and his heir in 1908, changing religious and social views, instability of the two political parties , the dictatorship of João Franco, and the regime's apparent inability to adapt to modern times all led to widespread resentment against the Monarchy. The proponents of the republic, particularly the Republican Party, found ways to take advantage of the situation. The Republican Party presented itself as the only one that had a programme that was capable of returning to the country its lost status and place Portugal on the way of progress. After a reluctance of the military to combat the nearly two thousand soldiers and sailors that rebelled between 3 and 4 October 1910, the Republic was proclaimed at 9 o'clock of the next day from the balcony of the Paços do Concelho in Lisbon. After the revolution, a provisional government led by Teófilo Braga directed the fate of the country until the approval of the Constitution in 1911 that marked the beginning of the First Republic. Among other things, with the establishment of the republic, national symbols were changed: the national anthem and the flag. The revolution produced some civil and religious liberties, although there was no advance in women's rights and in workers rights, unlike what happened in other European countries.

Answer: How many national symbols were changed with the beginning of the First Republic?


Question: Passage: In Week 11, the Lions hosted the Cleveland Browns in an interconference shootout. The Browns built a big lead in the first quarter, scoring first with a 44-yard field goal by Phil Dawson. After a 31-yard Jason Hanson field goal, Cleveland scored 21 points on Brady Quinn touchdowns to Mohamed Massaquoi (59 yards), Chansi Stuckey (40 yards), Joshua Cribbs (four yards). The Lions answered with three consecutive TD passes from Matthew Stafford to Aaron Brown (26 yards) and Kevin Smith (25 yards) and a 75-yard catch and run TD for Calvin Johnson. The Browns responded with a 29-yard field goal just before halftime. In the 3rd quarter Will Heller of the Lions caught a one-yard TD pass. The Browns received a safety when Stafford was tackled in his own end zone and called for intentional grounding. The Browns retook the lead on a two-yard TD catch by Michael Gaines and a Jamal Lewis two-point conversion. Stafford was intercepted on the next Lions possession, but the Lions stopped the Browns on 4th and 5. Then they drove 88 yards. With 2 seconds left, Stafford raced out of the pocket and threw a pass into the end zone which was intercepted by Brodney Pool, but the pick was nullified on a Hank Poteat pass interference penalty, giving the Lions one more play with no time left on the clock.  Stafford was brutally hit by two Browns defenders on the play, and suffered what turned out to be a major shoulder separation of his left (non-throwing) arm; he had to come out for the final play and backup Daunte Culpepper went in, but the Browns called time-out; under NFL rules injured players must come out for one play, and the Browns timeout thus made Stafford eligible to return to the field; he told the coaches he wanted to return for the final play (pleading to coaches "If you need me to throw the ball, I can throw the ball") and was allowed to go back in. He then threw a touchdown to Brandon Pettigrew, and Jason Hanson tacked on the extra point for the win. Stafford became the youngest QB to throw five touchdown passes in a game since the AFL-NFL merger in 1970. He also set a record for passing yards in a game by a rookie with 422. For his performance, Stafford won NFC Offensive Player of the Week and Pepsi Rookie of the Week. The game was made into an NFL Film, with Matthew Stafford mic'ed up. It was shown on NFL Network's NFL Replay and Wired for Sound and became a segment in the "Quarterback Duels" episode of NFL Top 10, as well as Showtime's Inside the NFL. The company's founder Steve Sabol said the Lions' game-winning drive was the most dramatic film he has seen in over 30 years.
