Task: Question Generation
Input (English): Passage: After the Battle of Deçiq Ottoman government decided for peaceful means of suppression of the revolt because frequent clashes with Albanians attracted the attention of the  European Great Powers. On 11 June sultan Mehmed V visited Skopje where he was greeted enthusiastically by the local population together with two Albanian chieftains who swore their allegiance to the Ottoman sultan. On 15 June, the date of the Battle of Kosovo, he visited the site of the historical battle greeted by 100.000 people. During his visit to Kosovo vilayet he signed a general amnesty for all participants of the Albanian revolts of 1910 and 1911. He was welcomed by the choir of the Serbian Orthodox Seminary with Turkish songs and vice-consul Milan Rakić had gathered a large contingent of Serbs, but many Albanians boycotted the event. Ottoman representatives managed to deal with the leaders of Albanian rebels in Kosovo Vilayet and Scutari Vilayet separately, because they were not united and lacked central control. The Ottoman Empire first managed to pacify the northern Albanian malësorë  from Scutari Vilayet reaching a compromise during a meeting in Podgorica. In order to resolve the problems in the south, the Ottoman representatives invited Albanian southern leaders to a meeting in Tepelenë on 18 August 1911. They promised to meet most of their demands, like general amnesty, the opening of Albanian language schools, and the restriction that military service was to be performed only in the territory of the vilayets with substantial Albanian population.  Other demands included requiring administrative officers to learn the Albanian language, and that the possession of weapons would be permitted.
Output (English): How many years did the Albanian revolt last?
