user: Input: Read this: In the early 1980s, a small but vocal segment of anthropologists and archaeologists attempted to demonstrate that contemporary groups usually identified as hunter-gatherers do not, in most cases, have a continuous history of hunting and gathering, and that in many cases their ancestors were agriculturalists and/or pastoralists[citation needed] who were pushed into marginal areas as a result of migrations, economic exploitation, and/or violent conflict (see, for example, the Kalahari Debate). The result of their effort has been the general acknowledgement that there has been complex interaction between hunter-gatherers and non-hunter-gatherers for millennia.[citation needed]
Question: What caused these one-time agriculturalists to become foragers??

Output: pushed into marginal areas


Input: Read this: Buckingham Palace finally became the principal royal residence in 1837, on the accession of Queen Victoria, who was the first monarch to reside there; her predecessor William IV had died before its completion. While the state rooms were a riot of gilt and colour, the necessities of the new palace were somewhat less luxurious. For one thing, it was reported the chimneys smoked so much that the fires had to be allowed to die down, and consequently the court shivered in icy magnificence. Ventilation was so bad that the interior smelled, and when a decision was taken to install gas lamps, there was a serious worry about the build-up of gas on the lower floors. It was also said that staff were lax and lazy and the palace was dirty. Following the queen's marriage in 1840, her husband, Prince Albert, concerned himself with a reorganisation of the household offices and staff, and with the design faults of the palace. The problems were all rectified by the close of 1840. However, the builders were to return within the decade.
Question: When did Buckingham officially become the only royal residence?

Input: Read this: The first Sky television rights agreement was worth £304 million over five seasons. The next contract, negotiated to start from the 1997–98 season, rose to £670 million over four seasons. The third contract was a £1.024 billion deal with BSkyB for the three seasons from 2001–02 to 2003–04. The league brought in £320 million from the sale of its international rights for the three-year period from 2004–05 to 2006–07. It sold the rights itself on a territory-by-territory basis. Sky's monopoly was broken from August 2006 when Setanta Sports was awarded rights to show two out of the six packages of matches available. This occurred following an insistence by the European Commission that exclusive rights should not be sold to one television company. Sky and Setanta paid a total of £1.7 billion, a two-thirds increase which took many commentators by surprise as it had been widely assumed that the value of the rights had levelled off following many years of rapid growth. Setanta also hold rights to a live 3 pm match solely for Irish viewers. The BBC has retained the rights to show highlights for the same three seasons (on Match of the Day) for £171.6 million, a 63 per cent increase on the £105 million it paid for the previous three-year period. Sky and BT have agreed to jointly pay £84.3 million for delayed television rights to 242 games (that is the right to broadcast them in full on television and over the internet) in most cases for a period of 50 hours after 10 pm on matchday. Overseas television rights fetched £625 million, nearly double the previous contract. The total raised from these deals is more than £2.7 billion, giving Premier League clubs an average media income from league games of around £40 million-a-year from 2007 to 2010.
Question: The first Sky television rights agreement was worth how much money over a six year period?

Output: unanswerable
