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.

Example input: Passage: The outbreak of the Seven Years' War in Europe in 1756 resulted in renewed conflict between French and British forces in India. The Third Carnatic War spread beyond southern India and into Bengal where British forces captured the French settlement of Chandernagore in 1757. However, the war was decided in the south, where the British successfully defended Madras, and Sir Eyre Coote decisively defeated the French, commanded by Comte de Lally at the Battle of Wandiwash in 1760. After Wandiwash, the French capital of Pondicherry fell to the British in 1761. The war concluded with the signing of the Treaty of Paris in 1763, which returned Chandernagore and Pondichery to France, and allowed the French to have "factories" in India but forbade French traders from administering them. The French agreed to support British client governments, thus ending French ambitions of an Indian empire and making the British the dominant foreign power in India.
Example output: Which french settlement did the British capture first, Chandernagore or Pondicherry?
Example explanation: This is a good question since it involves a comparison around a particular event, "British capturing the French settlement", which requires looking at more than a single sentence.
Q: Passage: Martin de Ursua used his conquest of the Itza as a stepping stone to achieving the coveted post of Governor-General of the Philippines, which he took up in 1709. European-introduced diseases devastated the native population of Peten, with the effects of disease compounded by the psychological impact of defeat. The population around Lake Peten Itza numbered between 20,000 and 40,000 in 1697. By 1714, a census recorded just over 3,000 individuals in Spanish Peten, including non-Indians. This number would not have included the so-called "wild" Maya living in the forest far from Spanish administration and control. By 1700 the new colonial capital of Peten was mainly inhabited by colonists, soldiers and convicts. During the second half of the 18th century, adult male Indians were heavily taxed, often being forced into debt peonage. Western Peten and neighbouring Chiapas remained sparsely populated, and the Maya inhabitants avoided contact with the Spanish. San Jose, on the northwest shore of lake Peten Itza, is the home of the last surviving speakers of the Itza language. The surname Kowoj still survives, but the Kowoj and Itza have fully merged and no longer exist as separate ethnicities. In modern times there is a history of conflict between San Jose and neighbouring San Andres , and this mutual hostility probably represents ancient hostility between the Itza and the Kowoj.
A:
How many is the difference between the minimum and maximum population estimates around Lake Peten Itza in 1697?
