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.

Ex Input:
Passage: The road building programme was also expanded, with capital expenditure increased to 8% of GDP, "the highest level achieved by any post-war government". Central government expenditure on roads went up from £125 million in 1963/64 to £225 million in 1967/68, while a number of road safety regulations were introduced, covering seat belts, lorry driver's hours, car and lorry standards, and an experimental 70 mile per hour speed limit. In Scotland, spending on trunk roads went up from £6.8 million in 1963/64 to £15.5 million in 1966/67, while in Wales, spending on Welsh roads went up from £21.2 million in 1963/64 to £31.4 million in 1966/67.

Ex Output:
By how many millions of pounds did the central government expenditure on roads go up between 1963 and 1968?

Passage: Coming off their third straight loss, Washington traveled to Oakland to play the Oakland Raiders for the first time since 2009. Washington got the ball to start the game, and punted. Oakland then followed with a punt, too. Washington went three-and-out yet again, but this time, Saverio Rocca's punt was blocked by Raiders running back Rashad Jennings and recovered by fellow Raiders running back Jeremy Stewart in the end zone for a Raiders touchdown and a 7-0 lead. Washington could not respond, and when Oakland got the ball again, quarterback Matt Flynn, filling in for concussed quarterback Terrelle Pryor found rookie tight end Mychal Rivera (brother of Glee star Naya Rivera) for a 31-yard score and a 14-0 Raiders lead. Needing a spark, Washington switched to a hurry-up offense for their next drive, and sustained one for the first time on the day. It stalled when it reached the red zone, however, and Washington placekicker John Potter hit a 25-yard chip shot to cut the deficit to 14-3. Later in the quarter, Matt Flynn threw a pass that was intercepted by cornerback David Amerson and returned 45 yards for a score and the deficit was 14-10. The teams were not able to do much else, and the halves concluded with this score at 14-10. In the third, both offenses continued to struggle, but late in the third, Washington quarterback Robert Griffin III found wide receiver Pierre Gar&#231;on for a 5-yard score, and Washington's first lead in the second half of a game all season. In the fourth, Oakland's offense continued to sputter, even fumbling for a second time at midfield. Washington was able to sustain a running game in spite of an injury to star running back Alfred Morris, with typical third-down back Roy Helu, Jr. running into the end zone from 14 yards out to increase Washington's lead to 24-14. Oakland could not rally, and Washington held on for its first win. With the win, Washington improved to 1-3 and heads into the bye week, reconvening on NBC Sunday Night Football for a clash with Dallas in two weeks. This was Washington's third consecutive win against an AFC opponent.

Ex Output:
How long was Flynn's touchdown pass?
