TASK DEFINITION: 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.
PROBLEM: Passage: As of the census of 2000, there were 19,234 people, 7,473 households, and 4,954 families residing in the village. The population density was 10,337.3 people per square mile (3,992.6/km²). There were 7,650 housing units at an average density of 4,111.5/sq mi (1,588.0/km²). The racial makeup of the village was 82.39% White (U.S. Census), 1.03% African American (U.S. Census), 0.29% Native American (U.S. Census), 4.52% Asian (U.S. Census), 0.04% Pacific Islander (U.S. Census), 3.93% from Race (United States Census), and 3.79% from two or more races. 13.03% of the population is Hispanic (U.S. Census) or Latino (U.S. Census) of any race.

SOLUTION: As of the 2000 census, how many percent of the population did not identify as white?

PROBLEM: Passage: Coming off their win over the Giants, the Cowboys stayed at home for a Week 16 interconference battle with the Baltimore Ravens, in what would be the final game at Texas Stadium. In the first quarter, Dallas struck first as rookie running back Tashard Choice got a 2-yard touchdown run.  The Ravens would respond with a 26-yard field goal from kicker Matt Stover.  Baltimore would take the lead in the second quarter as Stover got a 29-yard and a 37-yard field goal.  In the third quarter, the Ravens increased their lead as quarterback Joe Flacco completed a 13-yard touchdown pass to wide receiver Derrick Mason.  The Cowboys answered in the fourth quarter as kicker Nick Folk got a 35-yard field goal, but Baltimore answered right back with Stover's 35-yard field goal.  Dallas tried to rally as quarterback Tony Romo completed a 7-yard touchdown pass to wide receiver Terrell Owens, but the Ravens struck right back as running back Willis McGahee got a 77-yard touchdown run.  The Cowboys tried to come back as Romo completed a 21-yard touchdown pass to tight end Jason Witten, but the Ravens pulled away with fullback Le'Ron McClain's 82-yard touchdown run (the longest TD run that the Cowboys would ever give up during their tenure at Texas Stadium). With the loss, Dallas fell to 9-6 on the season and 0-3 all-time against the Ravens. For a while they lost their chances of controlling the NFC Wild Card spot, but got it back the next day with the Tampa Bay Buccaneers losing 41-24 to the San Diego Chargers.

SOLUTION: How long were each of Tony Romo's touchdown passes?

PROBLEM: Passage: The Cham also requested Ming China to intervene by helping bring the Vietnamese back in line by force and demarcate the border between Champa and Vietnam. China, however, only verbally rebuked the Vietnamese for its incursion, which the Vietnamese ignored, proceeding with its attack and plan to destroy its rival. The Vietnamese then carried out its campaign. On November 28, 1470, Le Thanh Tong formally launched his attack as a 100,000-strong Vietnamese naval expedition set out that day, followed by another Vietnamese army consisting of 150,000 men on December 8. The Vietnamese army was reorganized to copy the Chinese army, armed with gunpowder weapons. Le Thanh Tong raised a total of 300,000-strong army in the battlefied and, significantly outnumbering the 100,000-strong Cham army. This came at a massive financial cost since it drained the Vietnamese treasury of 1,000 gold liang each day. However, it decisively won the war.

SOLUTION:
After formally launching an attack, how many days later did Le Thanh Tong increase his army?
