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: After securing their first win of the season, the Browns went on the road to take on their archrival Pittsburgh Steelers. The Browns came into the game having lost their last 11 games against the Steelers. The Steelers struck first with two touchdown passes from Ben Roethlisberger in the 2nd quarter. Josh Cribbs ran a kickoff back 98 yards for a touchdown, and got the Browns within 7. However, the Browns could never close the gap, and fell to the Steelers, 27-14.

SOLUTION: How many games have the Browns won this season?

PROBLEM: Passage: The Eagles travelled to the west coast to take on the Los Angeles Chargers. Many Eagle fans invaded StubHub Center making it an unofficial home game for the Eagles (This would later be dubbed Lincoln Financial Field west by fans on Twitter). The Eagles jumped out to a 7-0 lead early, after Chris Long forced a fumble to set up an 8-yard touchdown pass from Carson Wentz to Alshon Jeffery. The Eagles would score on their first 5 drives of the game. Chargers quarterback Philip Rivers found Tyrell Williams for a 75-yard touchdown pass, trimming the lead to 13-7 midway through the 2nd quarter. The Eagles responded with a field goal to extend the lead. But, Chargers kicker Younghoe Koo kicked a field goal the change the scoreboard to 16-10 before halftime. The Eagles were up 19-17 when running back Wendell Smallwood ran for a three-yard touchdown, increasing the lead to 26-17. A touchdown drive capped off by Philip Rivers finding second year tight end Hunter Henry with 6:44 left in the game made the score 26-24. Riding LeGarrette Blount and his 136 yards, which included a 68-yard run, the Eagles were able to grind out the remaining time on the clock and hold on for their second close win in a row. The Eagles were overall efficient on offense. The defense played well despite giving up big plays and allowing Philip Rivers to throw 347 yards. With the win, the Eagles advanced to 3-1 maintaining a narrow 1 game lead in the NFC East.

SOLUTION: How many more yards was Philip Rivers first touchdown pass than Carson Wentz first touchdown pass?

PROBLEM: Passage: While the violence in the North was still raging, the South of Ireland was preoccupied with the split in the Dáil and in the IRA over the treaty. In April 1922, an executive of IRA officers repudiated the treaty and the authority of the Provisional Government which had been set up to administer it. These republicans held that the Dáil did not have the right to disestablish the Irish Republic. A hardline group of Anti-Treaty IRA men occupied several public buildings in Dublin in an effort to bring down the treaty and restart the war with the British. There were a number of armed confrontations between pro and anti-treaty troops before matters came to a head in late June 1922. Desperate to get the new Irish Free State off the ground and under British pressure, Michael Collins attacked the anti-treaty militants in Dublin, causing fighting to break out around the country. The subsequent Irish Civil War lasted until mid-1923 and cost the lives of many of the leaders of the independence movement, notably the head of the Provisional Government Michael Collins, ex-minister Cathal Brugha, and anti-treaty republicans Harry Boland, Rory O'Connor, Liam Mellows, Liam Lynch and many others: total casualties have never been determined but were perhaps higher than those in the earlier fighting against the British. President Arthur Griffith also died of a stroke during the conflict. Following the deaths of Griffith and Collins, W. T. Cosgrave became head of government. On 6 December 1922, following the coming into legal existence of the Irish Free State, W. T. Cosgrave became President of the Executive Council, the first internationally recognised head of an independent Irish government. The civil war ended in mid-1923 in defeat for the anti-treaty side.

SOLUTION:
Approximately how many years did the war last?
