This task is about creating an unanswerable question based on a given passage. Construct a question that looks relevant to the given context but is unanswerable. Following are a few suggestions about how to create unanswerable questions:
(i) create questions which require satisfying a constraint that is not mentioned in the passage
(ii) create questions which require information beyond what is provided in the passage in order to answer
(iii) replace an existing entity, number, date mentioned in the passage with other entity, number, date and use it in the question
(iv) create a question which is answerable from the passage and then replace one or two words by their antonyms or insert/remove negation words to make it unanswerable.

[Q]: Passage: While it is undisputed that early humans were hunters, the importance of this for the emergence of the Homo genus from the earlier Australopithecines, including the production of stone tools and eventually the control of fire, are emphasised in the hunting hypothesis and de-emphasised in scenarios that stress omnivory and social interaction, including mating behaviour, as essential in the emergence of human behavioural modernity. With the establishment of language, culture, and religion, hunting became a theme of stories and myths, as well as rituals such as dance and animal sacrifice.
[A]: What kind of activity would require the use of fire for early humans?


[Q]: Passage: Hitler's fierce anti-Soviet rhetoric was one of the reasons why the UK and France decided that Soviet participation in the 1938 Munich Conference regarding Czechoslovakia would be both dangerous and useless. The Munich Agreement that followed marked a partial German annexation of Czechoslovakia in late 1938 followed by its complete dissolution in March 1939, which as part of the appeasement of Germany conducted by Chamberlain's and Daladier's cabinets. This policy immediately raised the question of whether the Soviet Union could avoid being next on Hitler's list. The Soviet leadership believed that the West wanted to encourage German aggression in the East and that France and Britain might stay neutral in a war initiated by Germany, hoping that the warring states would wear each other out and put an end to both the Soviet Union and Nazi Germany.
[A]: What countries helped the Soviets from joining the Munich Conference?


[Q]: Passage: Following Nazi Germany's defeat in World War II in 1945, East Prussia was partitioned between Poland and the Soviet Union according to the Potsdam Conference. Southern East Prussia was placed under Polish administration, while northern East Prussia was divided between the Soviet republics of Russia (the Kaliningrad Oblast) and Lithuania (the constituent counties of the Klaipėda Region). The city of Königsberg was renamed Kaliningrad in 1946. The German population of the province largely evacuated during the war, but several hundreds of thousands died during the years 1944–46 and the remainder were subsequently expelled.
[A]:
In what year did the Potsdam Conference occur?
