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.

Example Input: Passage: Trying to end a three-game skid, the 49ers flew to Qwest Field for an NFC West rematch with the Seattle Seahawks on Thursday night.  In the first quarter, the Niners started off bumpy as Seahawks RB Shaun Alexander got a 3-yard TD run for Seattle's early strike and the only score of the period.  In the second quarter, San Francisco would get a field goal before halftime as kicker Joe Nedney nailed one from 39 yards out.  After a scorless third quarter, the Niners were in full force as QB Alex Smith completed an 8-yard TD pass to rookie TE Vernon Davis.  Afterwards, Smith would complete a 20-yard TD pass to RB Frank Gore.  Then, the 49ers wrapped the game up with Smith getting a very easy 18-yard QB sneak for a touchdown.  Seattle would get one more score as QB Matt Hasselbeck completed a 22-yard TD pass to TE Jerramy Stevens.  Fortunately, the Niners would get the win and the season sweep over the Seahawks.  With the win, the 49ers improved to 6-8.
Example Output: How long was Frank Gore's touchdown?

Example Input: Passage: The car also won the 1961 British Saloon Car Championship season, 1962 British Saloon Car Championship season, 1969 British Saloon Car Championship season, 1978 British Saloon Car Championship season and 1979 British Saloon Car Championship season, as well as the British Rally Championship in 1962, 1963 and 1970, the European Rally Championship in 1965 and 1966, and won the Finnish Rally Championship in 1965 and 1966. Minis also won the 1965 Lowood 4 Hour endurance race, and the final Finnish Grand Prix in 1963. The Cooper S also had some success in the European Touring Car Championship, winning in 1964 and 1968, the Guia Race of Macau (a 1-2-3 finish in 1965, a 1-2 finish in 1970 and a win in 1972), and the Australian Touring Car Championship, winning its class in 1962, 1963, 1964, 1966, 1967 and 1968. A further title was the 1971 Sun-7 Chesterfield Series. The Mini also enjoyed class wins at the 1963 Armstrong 500, repeating this feat every year until 1969 Hardie-Ferodo 500, and having class wins at the 1964, 1965 and 1971 Sandown 250, and Six Hour Le Mans in 1963, 1964, 1965, 1966, 1967, 1968, 1969, 1970 and 1972, as well as the 1971 Phillip Island 500K. The car also won the Welsh Sports and Saloon Car Championship in 1998. Mini Leyland came 4th place in the under-2-litre category in the 1966 Trans-Am season, 1967 Trans-Am season and 1969 Trans-Am seasons, improving to 3rd in 1970 Trans-Am season.
Example Output: How many British Saloon Car Championship seasons were won before 1970?

Example Input: Passage: During the 1970s the oil shocks (1973 oil crisis and 1979 energy crisis) hit Iceland hard. Inflation rose to 43% in 1974 and 59% in 1980, falling to 15% in 1987 but rising to 30% in 1988. Iceland experienced moderately strong GDP growth (3% on average) from 1995 to 2004. Growth slowed between 2000 and 2002, but the economy expanded by 4.3% in 2003 and grew by 6.2% in 2004. Growth in 2005 exceeded 6%. Inflation averaged merely 1.5% from 1993 to 1994, and only 1.7% from 1994 to 1995. Inflation over 2006 topped at 8.6%, with a rate of 6.9% as of January 2007. Standard & Poors reduced their rating for Iceland to AA- from A+ (long term) in December 2006, following a loosening of fiscal policy by the Icelandic government ahead of the 2007 elections. Foreign debt rose to more than five times the value of Icelands GDP, and Icelands Central Bank raised short-term interest rates to nearly 15% in 2007. Due to the plunging currency against the euro and dollar, in 2008 inflation was speculated to be at 20-25%.
Example Output:
How many percentage points higher was inflation in 1980 than in 1988 and the lowest estimate of 2008 combined?
