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 24,621 people, 9,029 households, and 6,284 families residing in the county.  The population density was 73 people per square mile (28/km²).  There were 12,064 housing units at an average density of 36 per square mile (14/km²).  The racial makeup of the county was 97.90% White (U.S. Census), 0.56% African American (U.S. Census), 0.15% Native American (U.S. Census), 0.28% Asian (U.S. Census), 0.02% Pacific Islander (U.S. Census), 0.36% from Race (United States Census), and 0.74% from two or more races. Hispanic (U.S. Census) or Latino (U.S. Census) of any race were 0.93% of the population. 21.3% were of English people, 16.5% Germans, 11.4% Irish people, 10.7% United States, 5.3% danish people and 5.3% Italian people ancestry according to Census 2000.

SOLUTION: How many in percent from the census weren't African American?

PROBLEM: Passage: Just days after teammate Sean Taylor died of his injuries, the Redskins tried to snap a three-game skid at home against the Buffalo Bills. Before the kickoff, the stadium held a memorial service for Sean Taylor, as well as players across the NFL wearing a #21 sticker on the back of their helmets. For the team's first defensive play, they would come out with only 10 players on the field, as their honor to Taylor. In the first quarter, the Redskins took the early lead as kicker Shaun Suisham managed to get a 27-yard field goal for the only score of the quarter. In the second quarter, the Redskins increased their lead as Suisham kicked a 28-yard field goal. Later, the Bills got on the board as linebacker Angelo Crowell sacked quarterback Jason Campbell in his end zone for a safety. The Redskins would end the half as Suisham kicked a 33-yard field goal. In the third quarter, the Bills drew closer as kicker Rian Lindell managed to get a 38-yard field goal. Later, the Redskins responded with running back Clinton Portis getting a 3-yard touchdown run. Afterwards, the Bills ended the half as Lindell kicked a 43-yard field goal. In the fourth quarter, the Bills drew closer as Lindell kicked a 24-yarder, along with a 33-yard field goal. Later, the Bills got into position to kick a 51-yard field goal. They got the kick, but Head Coach Joe Gibbs called timeout. When the Bills tried to kick again, Gibbs called timeout again, but unintentionally got his team an unsportsmanlike conduct penalty which not only moved the Bills 15 yards closer to their end zone but reduced Lindell's field goal attempt to 36 yards. Afterwards, the Bills ended the game with Lindell nailing the game-winning 36-yard field goal.

SOLUTION: How long was the longest field goal?

PROBLEM: Passage: Trying to break a five-game losing streak the Bengals flew to Lucas Oil Stadium for an AFC duel with the Colts. In the first quarter the Bengals had problems when kicker Adam Vinatieri got a 28-yard field goal, followed by QB Carson Palmer's pass being intercepted by CB Kelvin Hayden and returned 31 yards for a touchdown. This was followed in the second quarter by RB Javarris James getting a 3-yard TD run. They eventually scored with kicker Mike Nugent nailing a 27-yard field goal, followed by Palmer finding WR Chad Ochocinco on a 5-yard TD pass. The Bengals fell further behind when Vinatieri made a 47-yard field goal, followed in the fourth quarter by his 23-yard field goal. The Bengals only came back with 1 touchdown when Palmer connected to TE Jermaine Gresham on a 19-yard TD pass. With the loss, Cincinnati fell to 2-7 and surpassed their 2009 loss total.

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