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.

[Q]: Passage: The Lines of Communication were English Civil War fortifications commissioned by Parliament  and built around London between 1642 and 1643 to protect the capital from attack by the Royalist armies of Charles I. In 1642 some basic fortifications were built, in the form of street barricades and small earthworks. In 1643 a major construction effort was made, to provide a comprehensive ring of fortifications around the city. Much of the work was done by volunteer labour, organized by the trained bands and the livery companies. Up to 20,000 people are thought to be involved, and the works were completed in under two months. The fortifications failed their only test when the New Model Army entered London in 1647, and they were levelled by Parliament the same year.
[A]: How many months did it take them to build The Lines of Communication?


[Q]: Passage: Hoping to increase their current winning streak the Titans flew to Qualcomm Stadium for an AFC duel with the Chargers. In the first quarter the Titans took the lead when the Chargers' punt was blocked by Nick Schommer out of bounds for a safety. The Chargers replied with FB Mike Tolbert getting a 1-yard TD run. The Titans went on a scoring rally with kicker Rob Bironas nailing a 21-yard field goal, followed in the second quarter by QB Vince Young completing a 1-yard TD pass to TE Craig Stevens. They increased their lead with RB Chris Johnson getting a 29-yard TD run. The Chargers went on a scoring rally with RB Ryan Mathews making a 7-yard TD run, followed in the third quarter by kicker Kris Brown making a 34-yard field goal. Then QB Philip Rivers completed a 48-yard TD pass to TE Antonio Gates, and then Brown made a 36-yard field goal. The Titans tried to come back with Young finding WR Nate Washington on a 71-yard TD pass (with a failed 2-point conversion), but couldn't do anything after Rivers got a 13-yard TD pass to RB Darren Sproles.
[A]: From what distance did two players score touchdowns?


[Q]: Passage: Coming off their divisional home win over the Browns, the Ravens flew to Gillette Stadium for a Week 4 battle with the New England Patriots.  After Patriots kicker Stephen Gostkowski got a 32-yard field goal in the first quarter, Baltimore got into the game with quarterback Joe Flacco hooking up with wide receiver Derrick Mason on a 20-yard touchdown pass.  In the second quarter, New England came back with quarterback Tom Brady's 1-yard touchdown run and running back Sammy Morris' 12-yard touchdown run. The Ravens would reply in the third quarter with defensive end Terrell Suggs sacking Brady, causing a fumble which rolled into the Patriots' endzone, where defensive end Dwan Edwards would land on it for a touchdown.  New England would come right back with Brady's 14-yard touchdown pass to wide receiver Randy Moss.  Baltimore would play some catch-up in the fourth quarter as Flacco found running back Willis McGahee on a 13-yard touchdown pass, but the Patriots willingly replied with Gostkowski's 33-yard field goal.  Flacco would lead a last-minute drive, but New England's stiffened and came away with the win.
[A]:
How many field goals did Gostkowski kick in the first half?
