You will be given a definition of a task first, then some input of the task.
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.

Passage: The Italo-Turkish or Turco-Italian War was fought between the Kingdom of Italy and the Ottoman Empire from September 29, 1911, to October 18, 1912. As a result of this conflict, Italy captured the Ottoman Tripolitania Vilayet , of which the main sub-provinces were Fezzan, Cyrenaica, and Tripoli itself. These territories together formed what became known as Italian Libya. During the conflict, Italian forces also occupied the Dodecanese islands in the Aegean Sea. Italy had agreed to return the Dodecanese to the Ottoman Empire in the Treaty of Ouchy in 1912 Treaty of Lausanne). However, the vagueness of the text allowed a provisional Italian administration of the islands, and Turkey eventually renounced all claims on these islands in Article 15 of the 1923 Treaty of Lausanne. Although minor, the war was a significant precursor of the First World War as it sparked nationalism in the Balkan states. Seeing how easily the Italians had defeated the weakened Ottomans, the members of the Balkan League attacked the Ottoman Empire starting the First Balkan War before the war with Italy had ended. The Italo-Turkish War saw numerous technological changes, notably the airplane. On October 23, 1911, an Italian pilot, Captain Carlo Piazza, flew over Turkish lines on the world's first aerial reconnaissance mission, and on November 1, the first ever aerial bomb was dropped by Sottotenente Giulio Gavotti, on Turkish troops in Libya, from an early model of Etrich Taube aircraft. The Turks, lacking anti-aircraft weapons, were the first to shoot down an aeroplane by rifle fire.
Output:
How many countries were involved in the Italo-Turkish or Turco-Italian War?
