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: The effects of flooding can be devastating and cause significant damage to crops and houses, serious bank erosive with consequent loss of homesteads, school and land, and loss of many lives, livestock and fisheries. During the 1998 flood, over 70% of the land area of Bangladesh was inundated, affecting 31 million people and 1 million homesteads. In the 1998 flood which had an unusually long duration from July to September, claimed 918 human lives and was responsible for damaging 16 00 and 6000 km of roads and embankments respectively, and affecting 6000 km2 of standing crops. The 2004 floods, over 25% of the population of Bangladesh or 36 million people, was affected by the floods; 800 lives were lost; 952 000 houses were destroyed and 1.4 million were badly damaged; 24 000 educational institutions were affected including the destruction of 1200 primary schools, 2 million governments and private tubewells were affected, over 3 million latrines were damaged or washed away, this increases the risks of waterborne diseases including diarrhea and cholera. Also, 1.1 M ha of rice crop was submerged and lost before it could be harvested, with 7% of the yearly aus (early season) rice crop lost; 270 000 ha of grazing land was affected, 5600 livestock perished together with 254 00 poultry and 63 MT of lost fish production.

A: How many average people were affected per homestead?

Q: Passage: According to the Census Bureau, the median household income in 2013 was $36,836, down 7.9 percent from 2008 when the inflation-adjusted median household income was $40,008 (in 2013 dollars). For comparison, on an inflation-adjusted basis, the median household income among metropolitan areas was $60,482, down 8.2 percent in the same period, and the national median household income was $55,250, down 7.0 percent from 2008. The citys wealth disparity is evident when neighborhoods are compared. Residents in Society Hill had a 2013 median household income of $93,720, while residents in one of North Philadelphias districts reported the lowest median household income, $14,185.

A: How many dollars difference is the 2013 median household income for the residents in Society Hill compared to the lowest median household income in one of North Philadelphia's districts?

Q: Passage: The Raiders traveled to Denver for a week 7 AFC matchup for the ages. The game began with a 42-yard touchdown pass by Jason Campbell to tight-end Zach Miller to put the Raiders ahead 7-0 with 10:44 remaining in the first quarter. But only 8&#160;seconds later, on the Broncos' first play from scrimmage, Kyle Orton threw an interception to Chris Johnson which was returned 30&#160;yards for a touchdown. The Raiders now led 14-0 with 10:36 remaining. But then on the Broncos' next possession, Denver fumbled the ball, which was recovered by Oakland. The Raiders capitalized on the turnover with a 4-yard rushing touchdown by Darren McFadden. But the Raiders were not yet done, forcing the Broncos to a 4th down situation on their next drive and eventually making them turn the ball over on downs, adding a field goal to the score later in the quarter for the Raiders. At the end of the first quarter, Oakland led 24-0. Oakland began the second quarter with a 19-yard touchdown pass from Jason Campbell to Darren McFadden to make the Raiders lead 31-0. Later in the quarter, McFadden again rushed for another touchdown, making the Raiders lead over the Broncos 38-0.
