Definition: 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.
Input: 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:
By 2014, how many Georgians were actually able to return to their homes?
