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.

Passage: There are 186,440 people (up from 181,743 in 2000), 75,177 households, and 57,543 families residing in the city. This amounts to 6.75% of Utahs population, 18.11% of Salt Lake Countys population, and 16.58% of the new Salt Lake metropolitan population. The area within the city limits covers 14.2% of Salt Lake County. Salt Lake City is more densely populated than the surrounding metro area with a population density of 1,688.77/sq mi (1,049.36/km²). There are 80,724 housing units at an average density of 731.2 per square mile (454.35/km²).

Passage: After their win over the Jets, the Ravens stayed at home for a Week 3 interconference fight with the Arizona Cardinals.  In the first quarter, Baltimore took flight first with kicker Matt Stover getting a 21-yard field goal for the only score of the period.  In the second quarter, the Ravens increased its lead with Stover getting a 28-yard field goal.  The Cardinals would respond with kicker Neil Rackers getting a 48-yard field goal.  Afterwards, Baltimore began to unload with QB Steve McNair completing a 13-yard TD pass to WR Derrick Mason, while rookie WR Yamon Figurs returned a punt 75 yards for a touchdown. In the third quarter, Arizona managed to get a 40-yard field goal from Rackers, while the Ravens had Stover kick a 43-yard field goal.  However, in the fourth quarter, the Cardinals started to work their way back into the game with QB Kurt Warner completing a 5-yard and a 32-yard TD pass to WR Anquan Boldin, along with Rackers getting a 41-yard field goal to tie the game.  Stover helped Baltimore close out the game with a win as he nailed the game-winning 46-yard field goal as time expired.
How many field goals did Matt Stover make in the first half?

Passage: The profound demographic and economic changes that occurred in Finland after World War II affected the Finnish family. Families became smaller, dropping from an average of 3.6 persons in 1950 to an average of 2.7 by 1975. Family composition did not change much in that quarter of a century, however, and in 1975 the percentage of families that consisted of a man and a woman was 24.4; of a couple and children, 61.9; of a woman with offspring, 11.8; of a man and offspring, 1.9. These percentages are not markedly different from those of 1950. Change was seen in the number of children per family, which fell from an average of 2.24 in 1950 to an average of 1.7 in the mid-1980s, and large families were rare. Only 2 percent of families had four or more children, while 51 percent had one child; 38 percent, two children; and 9 percent, three children. The number of Finns under the age of 18 dropped from 1.5 million in 1960 to 1.2 million in 1980.

Did more families have one child or two children?
