instruction:
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.
question:
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.
answer:
After the withdrawal of the Ottoman army, how many parts of the country did the Italians seize?

question:
Passage: On 2 May, the German capital city, Berlin, fell to the Red Army. On 8 May 1945, the Germans surrendered unconditionally and the war in Europe officially ended. The Italians had quit the war in 1943, the Bulgarians in 1944, and the Hungarians earlier in 1945. Despite the German capitulation, however, sporadic fighting still took place in Yugoslavia. On 7 May, Zagreb was evacuated, on 9 May, Maribor and Ljubljana were captured by the Partisans, and General Alexander Löhr, Commander-in-Chief of Army Group E was forced to sign the total surrender of the forces under his command at Topolšica, near Velenje, Slovenia, on Wednesday 9 May 1945. Only the Croatian and other anti-Partisan forces remained. From 10 to 15 May, the Yugoslav Partisans continued to face resistance from Croatian, and other anti-Partisan forces throughout the rest of Croatia and Slovenia. The Battle of Poljana, the last battle of World War II in Europe, started on 14 May, ending on 15 May 1945 at Poljana, near Prevalje in Slovenia. It was the culmination and last of a series of battles between Yugoslav Partisans and a large  mixed column of German Army  soldiers together with Croatian Ustaše, Croatian Home Guard, Slovenian Home Guard, and other anti-Partisan forces who were attempting to retreat to Austria.
answer:

For how many days did the Yugoslav Partisans continue to face resistance from Croatian, and other anti-Partisan forces throughout the rest of Croatia and Slovenia after the war was officially over?
