Task: Question Generation
Input (English): Passage: Russia accused Georgia of committing "genocide" in South Ossetia. Russian officials initially claimed that up to 2,000 ethnic Ossetian civilians of Tskhinvali were killed by Georgian forces; according to Russia, the reason for the military intervention in Georgia was this large number of casualties. Public opinion among Ossetians was impacted by claims of high casualties; according to HRW, some Ossetian civilians said in interviews that they approved of burning and looting of Georgian villages because of the "thousands of civilian casualties in South Ossetia" reported by Russian television. In December 2008, the figures were revised down to a total of 162 South Ossetian casualties by the Investigative Committee of the Prosecutor's Office of the Russian Federation. Georgia and South Ossetia have filed complaints about alleged war crimes committed by the other side with international courts, including the International Criminal Court, the International Court of Justice, and the European Court of Human Rights. The war displaced a 192,000 people including both Ossetians and Georgians. Many were able to return to their homes after the war, but a year later around 30,000 ethnic Georgians remained displaced. As of May 2014, 20,272 persons remained displaced, with their return being blocked by de facto authorities.
Output (English): By 2014, how many Georgians were actually able to return to their homes?
