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: In cold and windy conditions, Brett Favre threw 2 interceptions, and the Bears blocked 2 punts, en route to a 35-7 victory over the Packers, giving the Bears a sweep against Green Bay for the 2007 season. The Packers had not had a punt blocked in 12 years (929 punts). The last time the Packers had 2 punts blocked in a game was September 21, 1975, in a game against Detroit. Favre ended the game with 158 passing yards, and he surpassed 4,000&#160;yards passing for the season, the 5th time in his career to achieve the mark.  Ryan Grant ran for 100 total yards and the only touchdown for the Packers. With the loss, the Packers fell to 12-3 on the season.

SOLUTION: How many points did Chicago win by?

PROBLEM: 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.

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

PROBLEM: Passage: Lower Silesia  is the northwestern part of the historical and geographical region of Silesia; Upper Silesia is to the southeast. Throughout its history Lower Silesia has been under the control of the medieval Kingdom of Poland, the Kingdom of Bohemia and the Austrian Habsburg Monarchy from 1526. In 1742 nearly all of the region was annexed by the Kingdom of Prussia and became part of the German Empire in 1871, except for a small part which formed the southern part of the Lower Silesian Duchy of Nysa and had been incorporated into Austrian Silesia in 1742. After 1945 the main part of the former Prussian Province of Lower Silesia fell to the Republic of Poland, while a smaller part west of the Oder-Neisse line remained within East Germany and historical parts of Austrian Lower Silesia  remained as a part of Czechoslovakia.

SOLUTION:
How many countries gained Lower Silesia territory after 1945?
