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: As of the census of 2000, there were 19,234 people, 7,473 households, and 4,954 families residing in the village. The population density was 10,337.3 people per square mile (3,992.6/km²). There were 7,650 housing units at an average density of 4,111.5/sq mi (1,588.0/km²). The racial makeup of the village was 82.39% White (U.S. Census), 1.03% African American (U.S. Census), 0.29% Native American (U.S. Census), 4.52% Asian (U.S. Census), 0.04% Pacific Islander (U.S. Census), 3.93% from Race (United States Census), and 3.79% from two or more races. 13.03% of the population is Hispanic (U.S. Census) or Latino (U.S. Census) of any race.

SOLUTION: As of the 2000 census, how many percent of the population did not identify as white?

PROBLEM: Passage: Hoping to rebound from their loss at Pittsburgh, the Patriots returned home for an interconference duel with the New York Giants, the first meeting since Super Bowl XLII where the Giants stopped their chances at going 19-0. After a scoreless first half, The Giants grabbed the lead in the third quarter, with a 22-yard field goal by placekicker Lawrence Tynes, followed by a 10-yard touchdown run by running back Brandon Jacobs. The Patriots got on the board, with a 32-yard field goal by placekicker Stephen Gostkowski. In the fourth quarter, the Patriots tied the game, with a 5-yard touchdown pass from quarterback Tom Brady to tight end Aaron Hernandez, then took the lead with a 45-yard field goal by Gostkowski. The Giants re-claimed the lead, with a 10-yard touchdown pass from quarterback Eli Manning to wide receiver Mario Manningham with three minutes remaining. The Patriots responded, with a 14-yard touchdown pass from Brady to tight end Rob Gronkowski. However, with a minute and a half remaining in a similar repeat of Super Bowl XLII, Manning led the Giants on a game-winning drive, culminating with a 1-yard touchdown pass to tight end Jake Ballard. With the loss, the Patriots dropped to 5-3, and QB Tom Brady's streak of 32 consecutive home wins was snapped.  Following the game the Patriots released Albert Haynesworth, who'd reportedly gotten into a sideline confrontation with assistant coach Pepper Johnson. The loss was the third time in nine seasons the Patriots had suffered consecutive losses, and only the second time the team has lost to an NFC team at Gillette Stadium. This was the 1st time the Patriots had a 2-game losing streak since Week 12 and Week 13 in 2009. The Giants and the Patriots would meet again in Super Bowl XLVI with the Giants winning 21-17.

SOLUTION: How many more yards was Gostkowski's second field goal over his first?

PROBLEM: Passage: The Kerma culture was an early civilization which flourished from around 2500 BC to about 1600 BC in Nubia, present day Sudan, centered at Kerma. It seems to have been one of a number of Sudanese states during the Middle Kingdom period of Ancient Egypt. In its latest phase, lasting from about 1700-1500 BC, it absorbed the Sudanese kingdom of Sai and became a sizable, populous empire rivaling Egypt. Around 1500 BC, it was absorbed into the Egyptian Empire, but rebellions continued for centuries. By the 11th century BC, the more 'Egyptianized' Kingdom of Kush emerged, apparently from Kerma, and regained the region's independence from Egypt.

SOLUTION:
Around how many centuries did the Kerma culture exist?
