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.

Input: Consider Input: Passage: The 8,878 housing units averaged 685.5 per square mile (264.7/km²), of which 6,287 (73.6%) were owner-occupied, and 2,256 (26.4%) were occupied by renters. The homeowner vacancy rate was 1.2%; the rental vacancy rate was 5.2%.  Around 17,769 people (77.1% of the population) lived in owner-occupied housing units and 5,280 people (22.9%) lived in rental housing units.

Output: How many more housing units were owner-occupied than occupied by renters?


Input: Consider Input: Passage: The Broncos donned their alternate orange jerseys and kicked off their 2011 season at home against their AFC West rival Oakland Raiders, the Broncos' first Week 1 home opener since 2004. The Broncos took an early lead in the first quarter, with a 28-yard field goal by placekicker Matt Prater. The Raiders reeled off 16 unanswered points in the second quarter, with a 3-yard touchdown pass from quarterback Jason Campbell to fullback Marcel Reece, followed by three field goals of 37, 21 and 63 yards by placekicker Sebastian Janikowski, the latter of which tied the record for the longest field goal in NFL history. The Broncos responded in the third quarter, with kick returner Eric Decker returning a punt 90 yards for a touchdown, followed by a 30-yard field goal by Prater. The Raiders increased their lead in the fourth quarter, with a 1-yard touchdown run by Campbell. The Broncos tried to rally, with quarterback Kyle Orton throwing a 9-yard touchdown pass to running back Lance Ball. However, Oakland would run out the clock.

Output: How many field goals between 25 and 65 yards were made?


Input: Consider Input: Passage: Houston is considered an Automobile dependency city, with an estimated 77.2% of commuters driving alone to work in 2016, up from 71.7% in 1990 and 75.6% in 2009. In 2016, another 11.4% of Houstonians carpooled to work, while 3.6% used public transit, 2.1% walked, and 0.5% bicycled. A commuting study estimated that the median length of commute in the region was  in 2012. According to the 2013 American Community Survey, the average work commute in Houston (city) takes 26.3 minutes. A 1999 Murdoch University study found that Houston had both the lengthiest commute and lowest urban density of 13 large American cities surveyed, and a 2017 Arcadis study ranked Houston 22nd out of 23 American cities in transportation sustainability. Harris County is one of the largest consumers of gasoline in the United States, ranking second (behind Los Angeles County, California) in 2013.


Output: How many more commuters in percentage drive alone in 2009 compared to 1990?
