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: Hoping to rebound from their divisional road loss to the Packers, the Vikings' Week 11 opponent was the Oakland Raiders, who had former Vikings quarterback Daunte Culpepper under center. After a 79-yard pass from wide receiver Sidney Rice to Visanthe Shiancoe on the first play from scrimmage, the Vikings scored on the very next play on a 10-yard run from Chester Taylor. This was followed by a safety when Culpepper was penalized for intentional grounding in his own endzone. Two plays after the ensuing free kick, the Vikings fumbled the ball just inside Oakland territory, allowing the Raiders to set up a 42-yard field goal for Sebastian Janikowski. On the next drive, the Vikings restored their nine-point lead as kicker Ryan Longwell hit a 30-yard field goal on the first play of the second quarter. A short Oakland drive culminating in 10-yard touchdown pass from Culpepper to tight end John Madsen, followed by another Janikowski field goal, saw the Raiders take the lead for the first time. Four plays later, Minnesota regained a six-point lead on a 38-yard touchdown run from Taylor, but field goals of 42 and 49 yards from Janikowski meant the first half ended with the scores level at 19-19. The Vikings recorded the only score of the third quarter on a 38-yard field goal from Longwell, though they did finish the period on the Raiders' 6-yard line, allowing Taylor to run in his third touchdown on the opening play of the fourth quarter, the first time in his career that he scored three touchdowns in one game. A 52-yard field goal from Janikowski narrowed the margin to 7 points with less than three-and-a-half minutes to play, and after forcing the Vikings to punt just inside the two-minute warning, they had one last chance to level the scores. On the first play of the drive, Culpepper threw the ball in the direction of Justin Fargas, who tipped it up, allowing Chad Greenway to come up with an interception; he went to ground with the ball, but inexplicably got up and attempted to advance it, which allowed left tackle Barry Sims to force a fumble, recovered by right guard Paul McQuistan. That enabled the Raiders to extend their drive, but although they managed to get into Vikings territory, a false start penalty meant Culpepper had to attempt a Hail Mary pass on the final play, but it came up short, giving the Vikings a 29-22 win.

SOLUTION: How many field goals did Janikowski kick during the first half?

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: Several 16th century writers estimated the 1492 population of Hispaniola at over 1 million people. 20th century estimates of the figure range from 60,000 to 8,000,000, but center around the 500,000 to 1,000,000 range. Harsh enslavement by Spanish colonists, as well as redirection of food supplies and labor towards the colonists, had a devastating impact on both mortality and fertility over the first quarter century. Colonial administrators and Dominican and Hyeronimite priests observed that the search for gold and agrarian enslavement through the encomienda system were depressing population. Demographic data from two provinces in 1514 shows a low birth rate consistent with a 3.5% annual population decline. Just 14,000 Taínos survived in 1517. In 1503 the colony began to import Ethnic groups of Africa slaves after a charter was passed in 1501 allowing the import of slaves by Ferdinand and Isabel. The Spanish believed Africans would be more capable of performing physical labor. From 1519 to 1533, the indigenous uprising known as Enriquillos Revolt ensued, resulting from escaped African slaves on the island possibly working with the Taino people.

SOLUTION:
How many years did the Enriquillos Revolt ensue?
