Task: Question Generation
Input (English): Passage: According to Finnish historians, the casualties of the Finnish Defence Forces amounted to 63,204 dead or missing and around 158,000 wounded. Officially, the Soviets captured 2,377 Finnish prisoners of war in the Soviet Union, although Finnish researchers estimated the number to be around 3,500 prisoners. 939 Finnish civilians died in air raids and 190 civilians were killed by Soviet partisans. Germany suffered approximately 84,000 casualties in the Finnish front, 16,400 killed, 60,400 wounded and 6,800 missing. In addition to the original peace terms of restoring the 1940 border, Finland was required to Finnish war reparations to the Soviet Union, conduct War-responsibility trials in Finland, lease Porkkalanniemi to the Soviets as well as ban fascist elements and allow left-wing groups, such as the Communist Party of Finland. A Soviet-led Allied Control Commission was installed to enforce and monitor the peace agreement in Finland. The requirement to disarm or expel any German troops left on Finnish soil by 15 September 1944 eventually escalated into the Lapland War between Finland and Germany and the evacuation of the 200,000-strong 20th Mountain Army to Norway.
Output (English): How many more men did the Finnish estimate were prisoners of war compared to the official number from the Soviet Union?
