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: Most of the fighting ended in continental North America in 1760, although it continued in Europe between France and Britain. The notable exception was the French seizure of St. John's, Newfoundland. General Amherst heard of this surprise action and immediately dispatched troops under his nephew William Amherst, who regained control of Newfoundland after the Battle of Signal Hill in September 1762. Many troops from North America were reassigned to participate in further British actions in the West Indies, including the capture of Spanish Havana when Spain belatedly entered the conflict on the side of France, and a British expedition against French Martinique in 1762 led by Major General Robert Monckton. General Amherst also oversaw the transition of French forts to British control in the western lands. The policies which he introduced in those lands disturbed large numbers of Indians and contributed to Pontiac's Rebellion in 1763. This series of attacks on frontier forts and settlements required the continued deployment of British troops, and it was not resolved until 1766.

SOLUTION: How many countries continued to fight after the fighting ended in continental North America in 1760?

PROBLEM: Passage: The Lines of Communication were English Civil War fortifications commissioned by Parliament  and built around London between 1642 and 1643 to protect the capital from attack by the Royalist armies of Charles I. In 1642 some basic fortifications were built, in the form of street barricades and small earthworks. In 1643 a major construction effort was made, to provide a comprehensive ring of fortifications around the city. Much of the work was done by volunteer labour, organized by the trained bands and the livery companies. Up to 20,000 people are thought to be involved, and the works were completed in under two months. The fortifications failed their only test when the New Model Army entered London in 1647, and they were levelled by Parliament the same year.

SOLUTION: How many months did it take them to build The Lines of Communication?

PROBLEM: Passage: On July 18, 2005, a nonviolent protest was held. The protest began in Netivot near Gaza. The protest march ended July 21 after police prevented protesters from continuing to Gush Katif. On August 2, 2005, another protest against disengagement began in Sderot, with approximately 50,000 attendees. On August 10, 2005, in response to calls from Jewish religious leaders, including former Chief Rabbis Avraham Shapira, Ovadia Yosef, and Mordechai Eliyahu, between 70,000 (police estimate) and 250,000 (organizers estimate) Jews gathered for a rally centered at the Western Wall in prayer to ask that the planned disengagement be cancelled. The crowds that showed up for the rally overwhelmed the Western Walls capacity and extended as far as the rest of the Old City and surrounding Jerusalem neighborhoods. The prayer rally was the largest of its kind for over 15 years, since the opposition to the Madrid Conference of 1991. On August 11, 2005, between 150,000 (police estimates) and 300,000 (organizers estimates) people massed in and around Tel Avivs Rabin Square for an anti-disengagement rally. Organizers called the event "the largest expression of public protest ever held in Israel."  According to a police spokesman, it was one of the largest rallies in recent memory.

SOLUTION:
How many attendees did police and organizer estimates differ by in the Tel Aviv rally?
