instruction:
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.
question:
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.
answer:
How many months did it take them to build The Lines of Communication?


question:
Passage: Coming off their home win over the Falcons, the Rams flew to Paul Brown Stadium for a Week 14 interconference duel with the Cincinnati Bengals.  With QB Marc Bulger out with a concussion and veteran back-up QB Gus Frerotte out with a shoulder injury, rookie QB Brock Berlin got his first NFL start. In the first quarter, St. Louis trailed early as Bengals RB Rudi Johnson got a 1-yard TD run for the only score of the period.  In the second quarter, the Rams continued to trail as kicker Shayne Graham gave Cincinnati a 27-yard field goal for the only score of the period. In the third quarter, St. Louis got on the board as CB Fakhir Brown returned an interception 36&#160;yards for a touchdown, yet the Bengals responded with Graham kicking a 38-yard and a 32-yard field goal.  In the fourth quarter, the Rams tried to come back as kicker Jeff Wilkins managed to get a 50-yard field goal.  However, Cincinnati sealed the win with Graham nailing a 46-yard field goal. This would also be the 5th time this year that the Rams were held to 10 or fewer points. On a positive note, WR Torry Holt went over 1,000 receiving yards for the eighth-straight year.
answer:
How many 30+ yard field goals did Graham make in the third quarter?


question:
Passage: Coming off huge home wins against the 49ers and Steelers, the Seahawks traveled to Minneapolis to take on the Minnesota Vikings. Despite being without both Marshawn Lynch and Jimmy Graham, the Seahawks dominated the Vikings 38-7. Going into the game, the Vikings were previously 8-3 and leading the NFC North, led the NFL in team rushing yards, and Adrian Peterson was the NFL's leading rusher. The Seahawks defense held Peterson to only 18 yards and the Vikings' offense failed to score (their only points coming on a special-teams kickoff return), while Russell Wilson and the Seattle offense racked up 433 yards, five total touchdowns, and no interceptions.
answer:

How did the Vikings' score?
