[Q]: Extract the answer to the question from the following context. Question: What is significant about the systeM? Context: New claims on Antarctica have been suspended since 1959 although Norway in 2015 formally defined Queen Maud Land as including the unclaimed area between it and the South Pole. Antarctica's status is regulated by the 1959 Antarctic Treaty and other related agreements, collectively called the Antarctic Treaty System. Antarctica is defined as all land and ice shelves south of 60 S for the purposes of the Treaty System. The treaty was signed by twelve countries including the Soviet Union (and later Russia), the United Kingdom, Argentina, Chile, Australia, and the United States. It set aside Antarctica as a scientific preserve, established freedom of scientific investigation and environmental protection, and banned military activity on Antarctica. This was the first arms control agreement established during the Cold War.

[Q]: Extract the answer to the question from the following context. Question: what is the last nation mentioned? Context: In 1955 American nuclear arms policy became one aimed primarily at arms control as opposed to disarmament. The failure of negotiations over arms until 1955 was due mainly to the refusal of the Russians to permit any sort of inspections. In talks located in London that year, they expressed a willingness to discuss inspections; the tables were then turned on Eisenhower, when he responded with an unwillingness on the part of the U.S. to permit inspections. In May of that year the Russians agreed to sign a treaty giving independence to Austria, and paved the way for a Geneva summit with the U.S., U.K. and France. At the Geneva Conference Eisenhower presented a proposal called "Open Skies" to facilitate disarmament, which included plans for Russia and the U.S. to provide mutual access to each other's skies for open surveillance of military infrastructure. Russian leader Nikita Khrushchev dismissed the proposal out of hand.

[Q]: Extract the answer to the question from the following context. Question: What did NASA falsely report? Context: On May 1, 1960, a U.S. one-man U-2 spy plane was reportedly shot down at high altitude over Soviet Union airspace. The flight was made to gain photo intelligence before the scheduled opening of an EastWest summit conference, which had been scheduled in Paris, 15 days later. Captain Francis Gary Powers had bailed out of his aircraft and was captured after parachuting down onto Russian soil. Four days after Powers disappeared, the Eisenhower Administration had NASA issue a very detailed press release noting that an aircraft had "gone missing" north of Turkey. It speculated that the pilot might have fallen unconscious while the autopilot was still engaged, and falsely claimed that "the pilot reported over the emergency frequency that he was experiencing oxygen difficulties."
