["Вторая мировая война (началась 01.09.1939 и закончилась 02.09.1945) — война двух мировых военно-политических коалиций, ставшая крупнейшим вооружённым конфликтом в истории человечества.В ней участвовали 62 государства из 74 существовавших на тот момент (80 % населения Земного шара).\nБоевые действия велись на территории Европы, Азии и Африки и в водах всех океанов. Это единственный конфликт, в котором было применено ядерное оружие. В результате войны погибло более 70 миллионов человек, из которых большинство — мирные жители.Число участвовавших стран менялось в течение войны. Некоторые из них вели активные военные действия, другие помогали Союзникам поставками продовольствия, а многие участвовали в войне только номинально.", "Было ли применено ядерное оружие?", 300, 1, 0.5, 0.4, 0.4],
