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.

[EX Q]: Passage: In the city, the population was distributed as 21.3% under the age of 18, 14.6% from 18 to 24, 33.2% from 25 to 44, 20.9% from 45 to 64, and 10.0% who were 65 years of age or older. The median age was 33 years. For every 100 females, there were 96.5 males. For every 100 females age 18 and over, there were 94.3 males.
[EX A]: How many in percent weren't 18 to 24?

[EX Q]: Passage: In 2011, the Thessaloniki (regional unit) had a Gross Domestic Product of Euro18.293 billion (ranked 2nd amongst the countrys regional units), comparable to Bahrain or Cyprus, and a per capita of €15,900 (ranked 16th). In Purchasing Power Parity, the same indicators are €19,851 billion (2nd) and €17,200 (15th) respectively. In terms of comparison with the European Union average, Thessalonikis GDP per capita indicator stands at 63% the EU average and 69% in Purchasing Power Parity – this is comparable to the German state of Brandenburg. Overall, Thessaloniki accounts for 8.9% of the total economy of Greece. Between 1995 and 2008 Thessalonikis GDP saw an average growth rate of 4.1% per annum (ranging from +14.5% in 1996 to −11.1% in 2005) while in 2011 the economy contracted by −7.8%.
[EX A]: Between 1995 and 1996, what was the GDP growth rate of Thessalonikis?

[EX Q]: Passage: The incorporated city fit into 4-5 square miles  as late as the First World War, but has since greatly expanded, crossing the Ashley River and encompassing James Island and some of Johns Island. The city limits also have expanded across the Cooper River, encompassing Daniel Island and the Cainhoy area. The present city has a total area of 127.5 square miles , of which 109.0 square miles  is land and 18.5 square miles  is covered by water. North Charleston blocks any expansion up the peninsula, and Mount Pleasant occupies the land directly east of the Cooper River. Charleston Harbor runs about 7 miles  southeast to the Atlantic with an average width of about 2 miles , surrounded on all sides except its entrance. Sullivan's Island lies to the north of the entrance and Morris Island to the south. The entrance itself is about 1 mile  wide; it was originally only 18 feet  deep, but began to be enlarged in the 1870s. The tidal rivers  are evidence of a submergent or drowned coastline. There is a submerged river delta off the mouth of the harbor and the Cooper River is deep.
[EX A]:
Charleston Harbor is roughly how many square miles?
