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: The index reached a relative intraday high—which was not exceeded for over seven years—of 1,552.87, on March 24, 2000, during the dot-com bubble. The index then declined by approximately 50%, to 768.63, on October 10, 2002, during the stock market downturn of 2002. On May 30, 2007, the S&P 500 closed at 1,530.23, to set its first all-time closing high in more than seven years. Although the index achieved a new all-time intraday high on October 11, 2007, at 1,576.09, following a record close of 1,565.15 on October 9, the index finished 2007 at 1,468.36 points—just below its 1999 annual close. Less than a month later, it dropped to 1,400, and would not see similar levels again for five years.

SOLUTION: How many points had the index gained from October 10, 2002 to October 11, 2007?

PROBLEM: Passage: 2010  The 2010 off-season would bring a surprise when on April 4, Eagles QB Donovan McNabb forced his team to trade him to the Redskins and was also marred by contract disputes with Albert Haynesworth. Washington continued an old tradition of playing its arch-rival Cowboys in the first week of the season. Both teams were unimpressive and the Redskins offense sputtered throughout the game, but they finally won 13-10 after a touchdown pass by Tony Romo was nullified after a holding call. They hosted the Texans in Week 2, but good all-around offensive performance (especially by McNabb, who passed for 426 yards and a touchdown) failed to secure a win. The game tied at 27-27 and went into overtime where Houston kicker Neil Rackers made a 37-yard FG, ending the match at 30-27. After this, the Redskins lost to St. Louis 30-16 before McNabbs return to Philadelphia. Although Washington did not deliver a particularly strong performance, they won 16-12 after Eagles QB Michael Vick was injured and replaced by Kevin Kolb. In Week 5, they hosted Green Bay for only the second time since 1979 (the first was in 2004) and beat them 16-13. After losing a Sunday Night match to the Colts, Washington beat Chicago in Week 7. Although McNabb threw two interceptions, the team took advantage of their opponents porous O-line to sack and pick off Jay Cutler (American football) four times, winning 17-14. After losing a 37-25 trap game in Detroit, the Redskins went on their bye week and returned to host Philadelphia on MNF for the second straight year. As rain fell on Fedex Field, the Eagles proceeded to crush Washington 59-28 with eight touchdowns. In contrast to the huge numbers put up by Michael Vick, McNabb looked decidedly unimpressive, with two touchdown passes and three interceptions (one returned for a TD). Just before the game, he had finalized his contract with the Redskins, who gave him a 5-year, $78 million deal and allowing him to (barring unforeseen circumstances) finish out his career in Washington. After beating Tennessee, the Redskins lost four straight games and were removed from playoff contention before beating Jacksonville in Week 16. After losing to New York at home, the Redskins finished the year at 6-10 and once again 4th place in the division.

SOLUTION: Against which teams did Washington score 16 points?

PROBLEM: Passage: With the Packers coming off of their first win since the injury of Aaron Rodgers, the Cowboys lead 26-3 at halftime. In the second half of the game, the Packers managed a dramatic comeback that was helped by the mistake-prone Cowboys. The Packers scored the game-winning touchdown with almost a minute left in the game. Tony Romo tried to rally back and give the Cowboys a win, but threw an interception near the 50-yard line that sealed their fate. Controversy followed the game for the Cowboys giving up a 23-point halftime lead and the play-calling of the coaching staff.

SOLUTION:
How many points did tje Cowboys lead by at halftime?
