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: According to the Moscow Armistice, signed by Finland and the victorious Allies, mainly the Soviet Union, the Finns were to try those who were responsible for the war and those who had committed war crimes. The Soviet Union allowed Finland to try its own war criminals, unlike other losing countries of the Second World War. The Finnish parliament had to create ex post facto laws for the trials, though in the case of war crimes the country had already signed the Hague IV Convention. In victorious Allied countries war-crime trials were exceptional, but Finland had to arrange full-scale investigations and trials, and report them for the Soviet Union. Criminal charges were filed against 1,381 Finnish POW camp staff members, resulting in 723 convictions and 658 acquittals. They were accused of 42 murders and 342 other homicides. Nine persons were sentenced to life sentences, 17 to imprisonment for 10-15 years, 57 to imprisonment for five to ten years, and 447 to imprisonment varying from one month to five years. Fines or disciplinary corrections were levied out in 124 cases. Although the criminal charges were highly politicized, some war crime charges were filed already during the Continuation War. However, most of them were not processed during wartime.
How many countries were mainly responsible for trying those accused of war crimes?
