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: On 5 March the British expedition sailed from Spithead, England, with 7 ships of the line and 4,365 men aboard 64 transports, and arrived in Barbados on 20 April.  Five days later the expedition reached Fort Royal on the recently conquered island of Martinique where it picked up the remainder of Major-General Robert Monckton's expedition, still numbering 8,461 men. Rear Admiral George Rodney's squadron, amounting to 8 ships of the line also joined the expedition bringing the total number of ships of the line to 15. On 23 May the expedition, now off the northwest corner of Saint-Domingue , was further reinforced by Sir James Douglas' squadron from Port Royal, Jamaica. The force under Albemarle now amounted to 21 ships of the line, 24 lesser warships, and 168 other vessels, carrying some 14,000 seamen and marines plus another 3,000 hired sailors and 12,826 regulars.

SOLUTION: How many days did it take for the British expedition to reach Barbados?

PROBLEM: Passage: In 1665, Charles II became the last male Habsburg King of Spain; suffering from ill-health all his life, his death was anticipated almost from birth and his successor debated for decades. In 1700, the Spanish Empire included possessions in Italy, the Spanish Netherlands, the Philippines and the Americas; while no longer the dominant power, it proved remarkably resilient and remained largely intact. Acquisition of an undivided Empire by the Habsburgs or Bourbons would change the balance of power and the conflict ultimately involved much of Europe. In making dynastic claims secondary, the war marks a key point in the development of the nation state. It was also the last of Louis XIV's wars to establish defensible borders and French supremacy in Europe, the most recent being the 1688-1697 Nine Years' War when France was unable to defeat the Grand Alliance. The 1697 Treaty of Ryswick was driven by mutual exhaustion and the recognition by Louis that he needed allies for a war over the Succession. Emperor Leopold initially refused to sign the Treaty since it left this issue unresolved; he reluctantly did so in October 1697 but most viewed Ryswick as only a pause in hostilities.

SOLUTION: France and Spain signed the Treaty of Ryswick due to what reasons?

PROBLEM: Passage: Although as of 2007 the population was declining, the decline was stabilizing and was more pronounced in urban areas. Out of the 19,667 births reported in 2007, 12,631 were in urban areas (11.86 per 1000) and 7,036 were in rural areas (14.88 per 1000). Birth rates for rural areas are 25% higher than that of urban areas. Of the total of 21,727 deaths, 14,366 were reported in urban areas (13.49 per 1000) and 7,361 were in rural areas (15.56 per 1000). Natural decline of population was measured at -0.16% for urban areas and an insignificant -0.07% for rural areas (average for Russia was -0.33% in 2007).

SOLUTION:
How many more births in 2007 were in urban areas than rural areas?
