Instructions: 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.
Input: Passage: The Treaty of Karlowitz, signed in January 1699, confirmed the Venetian possession of Kephalonia, and the Morea with the island of Aigina, which became organized as the "Kingdom of the Morea" , divided into four provinces: Romania, with seat at Nafplion , Laconia, with seat at Monemvasia , Messenia, with seat at Navarino, and Achaea, with seat at Patras . The war however had created a demographic and economic crisis in the Peloponnese. According to the first census conducted by the Venetians, there were 86,468 people in the peninsula compared to a pre-war population of around 200,000. Although the Venetians managed to restore some prosperity - the population allegedly rose to some 250,000 by 1708, probably driven by immigration - they failed to win the trust of their Greek Orthodox subjects, who were used to a relative autonomy under the Turks and resented the Venetian bureaucracy. The Venetians also launched a great fortification project throughout the Morea, whose results can still be seen today. Nevertheless, Venice itself was too weakened to effectively assert its authority, and in 1715 a swift Ottoman campaign reclaimed the Morea.
Output:
Approximately how many Venetians perished in the war?
