Here is a question about this article: 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.
What is the answer to this question: What document regulates Antarctica's status?

So... Antarctic Treaty System

Here is a question about this article: In the dense areas, most of the concentration is via medium- and high-rise buildings. London's skyscrapers such as 30 St Mary Axe, Tower 42, the Broadgate Tower and One Canada Square are mostly in the two financial districts, the City of London and Canary Wharf. High-rise development is restricted at certain sites if it would obstruct protected views of St Paul's Cathedral and other historic buildings. Nevertheless, there are a number of very tall skyscrapers in central London (see Tall buildings in London), including the 95-storey Shard London Bridge, the tallest building in the European Union.
What is the answer to this question: Most of London's skyscrapers are located where?

So... in the two financial districts

Here is a question about this article: Present-day Slavic people are classified into West Slavic (chiefly Poles, Czechs and Slovaks), East Slavic (chiefly Russians, Belarusians, and Ukrainians), and South Slavic (chiefly Serbs, Bulgarians, Croats, Bosniaks, Macedonians, Slovenes, and Montenegrins), though sometimes the West Slavs and East Slavs are combined into a single group known as North Slavs. For a more comprehensive list, see the ethnocultural subdivisions. Modern Slavic nations and ethnic groups are considerably diverse both genetically and culturally, and relations between them even within the individual ethnic groups themselves are varied, ranging from a sense of connection to mutual feelings of hostility.
What is the answer to this question: East Slavic people consist of which nationalities?
