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 Texans' defense was unable to withstand the Bills' rushing offense, especially in the first half, allowing over 100 rushing yards. Nonetheless, Houston managed to keep pace throughout despite not leading all game, but gave up a go-ahead touchdown by Charles Clay on the first play off the two-minute warning, followed by Dan Carpenter's 30-yard field goal to put it away for good. The Texans lost their first game following the bye week losing to Buffalo 21-30 and dropped to 6-6 on the season. This was also Houston's first loss to the Bills since 2006.

Answer: How many points did Buffalo win by?


Question: Passage: For their annual Thanksgiving Day game, the Lions hosted the Houston Texans. The Lions got on the board early when Mikel Leshoure ran in a touchdown from 2 yards out. The score sea-sawed in the second quarter, with each team scoring a pair of touchdowns. First, the Texans' Arian Foster rushed in a touchdown from 6 yards out. The Lions responded with a 5-yard touchdown run from Mike Foster. Houston's Owen Daniels then caught a 9-yard touchdown pass from Matt Schaub. The Lions' Calvin Johnson then caught a 22-yard touchdown pass. After halftime, Detroit's Jason Hanson kicked a 46-yard field goal. Houston responded with an 81-yard touchdown rush by Justin Forsett, which would have been overturned by an official review, but Coach Jim Schwartz's challenge flag negated the review. The Texans tied it up yet again with a 45-yard field goal by Shayne Graham. In the fourth quarter, the Lions took the lead back with a 23-yard touchdown run by Joique Bell, but Houston tied it back up with a 1-yard run by Arian Foster inside the 2-minute warning to take it to overtime. After a pair of turnovers and missed field goals by each team, Houston's Shayne Graham kicked the game-winning field goal from 32-yards out. It was the Lions' ninth consecutive Thanksgiving loss.

Answer:
How long was Mike Foster's touchdown run?
