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.

[Q]: Passage: The invasion of Libya was a costly enterprise for Italy. Instead of the 30 million lire a month judged sufficient at its beginning, it reached a cost of 80 million a month for a much longer period than was originally estimated. The war cost Italy 1.3 billion lire, nearly a billion more than Giovanni Giolitti estimated before the war. This ruined ten years of fiscal prudence. After the withdrawal of the Ottoman army the Italians could easily extend their occupation of the country, seizing East Tripolitania, Ghadames, the Djebel and Fezzan with Murzuk during 1913. The outbreak of the First World War with the necessity to bring back the troops to Italy, the proclamation of the Jihad by the Ottomans and the uprising of the Libyans in Tripolitania forced the Italians to abandon all occupied territory and to entrench themselves in Tripoli, Derna, and on the coast of Cyrenaica. The Italian control over much of the interior of Libya remained ineffective until the late 1920s, when forces under the Generals Pietro Badoglio and Rodolfo Graziani waged bloody pacification campaigns. Resistance petered out only after the execution of the rebel leader Omar Mukhtar on September 15, 1931. The result of the Italian colonisation for the Libyan population was that by the mid-1930s it had been cut in half due to emigration, famine, and war casualties. The Libyan population in 1950 was at the same level as in 1911, approximately 1.5 million.
[A]: After the withdrawal of the Ottoman army, how many parts of the country did the Italians seize?

[Q]: Passage: In 1545, Polin was on his way to fight against the English in the area of Boulogne. While in Marseilles in 1545, Polin was involved as a leader in the massacre of the Protestant Waldensians . Outside the Piedmont the Waldenses joined the local Protestant churches in Bohemia, France and Germany. After they came out of clandestinity and reports were made of sedition on their part, the French king, Francis I issued on 1 January 1545 the "Arret de Merindol", and armed a crusade against the Waldensians of Provence. The leaders in the 1545 massacres were Jean Maynier d'Oppede, First President of the parlement of Provence, and Antoine Escalin des Aimars who was returning from the Italian Wars with 2,000 veterans, the Bandes de Piemont. Deaths ranged from hundreds to thousands, depending on the estimates, and several villages were devastated.
[A]: How many countries did the Waldenses join the local Protestant churches in?

[Q]: Passage: The French king, John II, had been held captive in England. The Treaty of Bretigny set his ransom at 3millioncrowns and allowed for hostages to be held in lieu of John. The hostages included two of his sons, several princes and nobles, four inhabitants of Paris, and two citizens from each of the nineteen principal towns of France. While these hostages were held, John returned to France to try and raise funds to pay the ransom. In 1362 John's son Louis of Anjou, a hostage in English-held Calais, escaped captivity. So, with his stand-in hostage gone, John felt honor-bound to return to captivity in England. The French crown had been at odds with Navarre since 1354, and in 1363 the Navarrese used the captivity of John II in London and the political weakness of the Dauphin to try to seize power. Although there was no formal treaty, Edward III supported the Navarrese moves, particularly as there was a prospect that he might gain control over the northern and western provinces as a consequence. With this in mind, Edward deliberately slowed the peace negotiations. In 1364, John II died in London, while still in honourable captivity. Charles V succeeded him as king of France. On 7 May 1364, one month after the dauphin's accession and three days before his coronation as Charles V, the Navarrese suffered a crushing defeat at the Battle of Cocherel.
[A]:
At least how many people were held hostage in place of John II?
