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: Coming off their win over the Titans, the Dolphins stayed at home for a Week 11 interconference duel with the Chicago Bears on Thursday night.  Miami trailed early in the first quarter as Bears kicker Robbie Gould got a 46-yard field goal.  Chicago added onto their lead in the second quarter with Gould making a 24-yard field goal. The Bears continued to increase their lead with Gould's 50-yard field goal, followed by a touchdown scored by running back Matt Fort&#233;. This was the final score of the game, with Chicago's defense preventing any score by the Dolphins.
answer:
How long were each of Robbie Gould's field goals?


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: Oldsmobile also introduced a 5.7L (350 cu-in, V8) Oldsmobile Diesel engine option on its Custom Cruiser, Delta 88 and 98 models in 1978 and a smaller 4.3L (260 cu-in, V8) displacement diesel on the 1979 Cutlass Salon and Cutlass Supreme/Cutlass Calais models. These were largely based on their gasoline engines but with heavier duty cast blocks, re-designed heads, fast glow plugs, and on the 5.7L, oversized cranks, main bearings, and wrist pins. There were several problems with these engines, including water and corrosion in the injectors (no water separator in the fuel line), paraffin clogging of fuel lines and filters in cold weather, reduced lubrication in the heads due to undersized oil galleys, head bolt failures, and the use of aluminum rockers and stanchions in the 4.3L V8 engines. While the 5.7L was also offered on various Buick, Cadillac, Chevrolet, GMC, and Pontiac models, it was eventually discontinued by all divisions in 1985.  4.3L V6 diesels were also offered between 1982 and 1985.
answer:

How many models did Oldsmobile offer a 5.7L engine in in 1978?
