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.

Example Input: Passage: The 8,878 housing units averaged 685.5 per square mile (264.7/km), 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.
Example Output: How many more housing units were owner-occupied than occupied by renters?

Example Input: Passage: After their success in the Morea, the Ottomans moved against the Venetian-held Ionian Islands. They occupied the island of Lefkada , which the Venetians had taken in 1684, and the fort of Butrinto opposite the city of Corfu. On 8 July 1716, an Ottoman army of 33,000 men landed on Corfu, the most important of the Ionian islands. Despite an indecisive naval battle on the same day, the Ottoman land army continued its disembarkment and advanced towards the city of Corfu. On 19 July, after capturing the outlying forts of Mantouki, Garitsa, Avrami and of the Saviour, the siege began. The defence was led by Count Johann Matthias von der Schulenburg, who had roughly 8,000 men at his command. The extensive fortifications and the determination of the defenders withstood several assaults. After a great storm on 9 Augustwhich the defenders attributed to the intervention of Corfu's patron saint, Saint Spyridoncaused significant casualties among the besiegers, the siege was broken off on 11 August and the last Ottoman forces withdrew on 20 August.
Example Output: How many days after a great storm was the siege broken off?

Example Input: Passage: The Texans opened the 2006 season at home against the Philadelphia Eagles on September 10. The Texans looked sharp early with QB David Carr throwing a 25-yard TD pass to former Bills WR Eric Moulds in the 1st Quarter. The Eagles would tie the game with QB Donovan McNabb throwing a 42-yard TD strike to WR Donte' Stallworth. The Texans would retake the lead, however, after a 34-yard FG from K Kris Brown. Philadelphia took the lead late in the half with McNabb throwing a 5-yard TD pass to WR Reggie Brown and held on to it for the rest of the game. In the third quarter, McNabb hooked up with RB Brian Westbrook with a 31-yard pass and then, opposing kicker David Akers ended the game in the fourth quarter with a 42-yard field goal. David Carr finished 18-of-27 for 208 yards and a touchdown and was sacked five times.
Example Output:
Did the Texans play their first game of the 2006 at home or on the road?
