Input: Consider Input: Passage: YouTube entered into a marketing and advertising partnership with NBC in June 2006. In November 2008, YouTube reached an agreement with MGM, Lions Gate Entertainment, and CBS, allowing the companies to post full-length films and television episodes on the site, accompanied by advertisements in a section for US viewers called "Shows". The move was intended to create competition with websites such as Hulu, which features material from NBC, Fox, and Disney. In November 2009, YouTube launched a version of "Shows" available to UK viewers, offering around 4,000 full-length shows from more than 60 partners. In January 2010, YouTube introduced an online film rentals service, which is available only to users in the US, Canada and the UK as of 2010. The service offers over 6,000 films.

Input: Consider Input: Passage: When Estonia was invaded and occupied by the Soviet Union in World War II, the status of the Estonian language changed to the first of two official languages (Russian being the other one). As with Latvia many immigrants entered Estonia under Soviet encouragement. In the second half of the 1970s, the pressure of bilingualism (for Estonians) intensified, resulting in widespread knowledge of Russian throughout the country. The Russian language was termed as ‘the language of friendship of nations’ and was taught to Estonian children, sometimes as early as in kindergarten. Although teaching Estonian to non-Estonians in schools was compulsory, in practice learning the language was often considered unnecessary.

Output: What country did not occupy Estonia? 


Input: Consider Input: Passage: Fraser maintained some of the social reforms of the Whitlam era, while seeking increased fiscal restraint. His government included the first Aboriginal federal parliamentarian, Neville Bonner, and in 1976, Parliament passed the Aboriginal Land Rights Act 1976, which, while limited to the Northern Territory, affirmed "inalienable" freehold title to some traditional lands. Fraser established the multicultural broadcaster SBS, accepted Vietnamese refugees, opposed minority white rule in Apartheid South Africa and Rhodesia and opposed Soviet expansionism. A significant program of economic reform however was not pursued. By 1983, the Australian economy was suffering with the early 1980s recession and amidst the effects of a severe drought. Fraser had promoted "states' rights" and his government refused to use Commonwealth powers to stop the construction of the Franklin Dam in Tasmania in 1982. Liberal minister, Don Chipp split off from the party to form a new social liberal party, the Australian Democrats in 1977. Fraser won further substantial majorities at the 1977 and 1980 elections, before losing to the Bob Hawke led Australian Labor Party in the 1983 election.


Output: Which document allowed for Indigenous peoples the right to Tasmania?
