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: Obesity is one of the leading preventable causes of death worldwide. A number of reviews have found that mortality risk is lowest at a BMI of 20–25 kg/m2 in non-smokers and at 24–27 kg/m2 in current smokers, with risk increasing along with changes in either direction. This appears to apply in at least four continents. In contrast, a 2013 review found that grade 1 obesity (BMI 30–35) was not associated with higher mortality than normal weight, and that overweight (BMI 25–30) was associated with "lower" mortality than was normal weight (BMI 18.5–25). Other evidence suggests that the association of BMI and waist circumference with mortality is U- or J-shaped, while the association between waist-to-hip ratio and waist-to-height ratio with mortality is more positive. In Asians the risk of negative health effects begins to increase between 22–25 kg/m2. A BMI above 32 kg/m2 has been associated with a doubled mortality rate among women over a 16-year period. Obesity in the United States, obesity is estimated to cause 111,909 to 365,000 deaths per year, while 1 million (7.7%) of deaths in Europe are attributed to excess weight.  On average, obesity reduces life expectancy by six to seven years, a BMI of 30–35 kg/m2 reduces life expectancy by two to four years, while severe obesity (BMI > 40 kg/m2) reduces life expectancy by ten years.

A: What BMI reduces life expectancy for ten years, BMI of 30–35 kg/m2 or BMI > 40 kg/m2?

Q: Passage: More than 5,000 US troops of General John J. Pershing's forces, including elements of the 7th Cavalry and the African-American U.S. 10th Cavalry Regiment, entered Mexico in hot pursuit of Villa. The campaign consisted primarily of dozens of minor skirmishes with small bands of insurgents. Gen. Pershing failed to catch up to Villa. On 21 June 1916, two troops of the 10th, totaling 92 troopers, attacked Mexican Federal Army troops in an engagement in the Battle of Carrizal, Chihuahua. 12 US troops were killed and 23 taken prisoner; 45 Federales were casualties, including the Mexican general Gomez. The engagement nearly precipitated open war with the Mexican government , but both governments immediately moved to lessen tensions and open negotiations for US withdrawal, preventing war. The prisoners were repatriated at El Paso, Texas by the Carrancista government.

A: How many US troops in the Battle of Carrizal, Chihuahua were killed or taken prisoner?

Q: Passage: Hoping to rebound from their divisional road loss to the Texans, the Titans went home for a crucial Week 16 battle with the Pittsburgh Steelers, with the AFC's top seed on the line. After a scoreless first quarter, the Titans got the second quarter lead as kicker Rob Bironas got a 42-yard field goal, along with quarterback Kerry Collins completing a 34-yard touchdown pass to wide receiver Justin Gage. The Steelers would respond with quarterback Ben Roethlisberger completing a 31-yard touchdown pass to wide receiver Santonio Holmes. In the third quarter, Pittsburgh took the lead as Roethlisberger completed a 21-yard touchdown pass to wide receiver Hines Ward, yet Tennessee struck back with rookie running back Chris Johnson getting a 21-yard touchdown run. The Titans would then pull away in the fourth quarter with running back LenDale White's 1-yard touchdown run and safety Michael Griffin's 83-yard interception return for a touchdown. This was the first game of the year where the league-leading Steelers defense allowed more than 300 yards of total offense (allowing 332 yards). With the win, not only did Tennessee improve to 13-2, but they also locked up the AFC's #1 seed. This would be the Titans last win until Week 8 of the 2009 season. This would also be the last time a team swept both the AFC and NFC North in the same season until the Dallas Cowboys did it during the 2016 season.

A:
By which means produced the longest touchdown?
