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: 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: The Steelers traveled to Chicago to take on the Bears. In the first quarter, the Bears scored first when Jordan Howard ran for a 3-yard touchdown to take a 7-0 lead for the only score of the quarter. In the second quarter, the Steelers managed to tie it up at 7-7 when Ben Roethlisberger found Antonio Brown on a 7-yard pass. The Bears moved ahead by double digits later on when Mike Glennon found Adam Shaheen on a 2-yard pass to make it 14-7. This would be followed up by Connor Barth's 24-yard field goal to make it 17-7 at halftime. After the break, the Steelers got back to work and came within 3 as Le'Veon Bell ran for a 1-yard touchdown to make it 17-14. They would tie the game up in the fourth quarter when Chris Boswell nailed a 32-yard field goal. The Steelers then tried their hand at coming back for the win later on in the quarter, but Roethlisberger was sacked in Bears territory, sending the game into overtime. In overtime, the Bears got the ball. They would win it by way of Howard's 19-yard run for a touchdown and the final score 23-17. With the loss and 9-game regular season winning streak snapped, the Steelers dropped to 2-1 and with the Ravens' loss to the Jaguars moved into a tie on top of the AFC North.
