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.

Passage: Worldwide sales of hybrid vehicles produced by Toyota reached 1 million vehicles by May 31, 2007, and the 2 million mark was reached by August 2009, with hybrids sold in 50 countries. The 5 million hybrid sales milestone was reached in March 2013. During 2012, Toyota and Lexus hybrid models sold more than 1 million units a year for the first time, with 1.219 million units sold. During 2013, TMC sold 1.279 million units, and the 6 million sales milestone was achieved in December 2013, just nine months after its latest million unit milestone. The 7 million sales mark was reached in September 2014, again, selling one million hybrids in nine months, and the 8 million sales milestone was achieved in July 2015, just 10 months after the previous million-unit milestone. The 9 million sales mark was reached in April 2016, again, selling one million hybrids in just nine months, and the 10 million milestone in January 2017, one more time nine months later. Toyota estimates that up to January 31, 2017, its hybrids have saved about 7.66 billion U.S. gallons of gasoline (29 billion liters) compared to the amount used by gasoline-powered vehicles of similar size, and have emitted approximately 77 million fewer tons of CO2 emissions than would have been emitted by gasoline-powered vehicles of similar size and driving performance.
Did it take longer to go from 6 - 7 million units sold, or from 7 - 8 million units sold?

Passage: Coming off their dominating road win over the Jaguars, the Eagles went home for their Week 4 NFC East duel with the Washington Redskins, as quarterback Donovan McNabb made his highly anticipated return to Philadelphia. The Eagles trailed in the first quarter as Redskins running back Ryan Torain got a 12-yard touchdown run, followed by McNabb's 31-yard touchdown pass to tight end Chris Cooley. Philadelphia answered in the second quarter with kicker David Akers making a 49-yard field goal, but Washington came right back with kicker Graham Gano's 26-yard field goal. Afterwards, the Eagles closed out the half with Akers' 23-yard field goal. After a scoreless third quarter, Philadelphia tried to rally in the fourth quarter as quarterback Kevin Kolb hooked up with tight end Brent Celek. However, the Redskins' defense prevented any further progress.
How many field goals did Akers make?

Passage: In 1756, the Marquis de Vaudreuil was informed that King Louis XV of France was sending the Marquis Louis-Joseph de Montcalm to take over French forces in North America, with Levis as second in command. Vaudreuil wrote back that there was no need to send another general, as Vaudreuil disliked the tactics of most "municipal" French generals. When Montcalm arrived despite Vaudreuil's protest, the two men developed a dislike for each other. Levis diplomatically cultivated good relations with both men, and managed to avoid getting dragged into the feuds between the two. Levis led the vanguard of the French expedition to Fort William Henry in 1757, and laid siege to it until Montcalm's arrival. During French planning for the 1758 campaign in the French and Indian War the disputes between Vaudreuil and Montcalm continued. Vaudreuil prevailed, and Montcalm was sent to Fort Carillon to defend it against an expected British attack. Levis was initially slated to lead an expedition to the western forts, leading about 500 French metropolitan troops and a large seasoned French-Canadian militia. Vaudreuil, however, had second thoughts, and dispatched Levis and his metropolitan troops to support Montcalm at Carillon. Levis arrived at Carillon on the evening of July 7, as a British army was arriving before the fort. The next day, in a stroke of good fortune for the defenders, the 16,000 strong British army under the command of General James Abercrombie decided to frontally attack the French defenses manned by about 4,000 men, without the benefit of artillery support. In the Battle of Carillon, the British were decisively defeated, with Levis leading the defense on the French right flank.
How many more men did the British army under General James Abercrombie have than the French defenses?
