Question: What university was opened by the Prime Minister of the United Kingdom from 1979 to 1990?

<P0-S0> William Henry Cavendish Cavendish-Bentinck, 3rd Duke of Portland, (14 April 1738 – 30 October 1809) was a British Whig and Tory statesman, Chancellor of the University of Oxford, Prime Minister of Great Britain, serving in 1783 and Prime Minister of the United Kingdom from 1807 to 1809. <P0-S1>  The 24 years between his two terms as Prime Minister is the longest gap between terms of office of any Prime Minister. <P0-S2>  He was known before 1762 by the courtesy title Marquess of Titchfield. <P0-S3>  He held a title of every degree of British nobility—Duke, Marquess, Earl, Viscount, and Baron. <P0-S4>  He is also a great-great-great-grandfather of Queen Elizabeth II through her maternal grandmother. <SEP> <P1-S0> The University of Warwick Science Park (also known as UWSP and Warwick Science Park) was one of the first university based science parks in the United Kingdom when it was opened by the Rt. <P1-S1>  Hon. Margaret Thatcher in 1984. <P1-S2>  It was a joint venture between the University of Warwick, Coventry City Council, Warwickshire County Council and Barclays. <P1-S3>  The latter are no longer shareholders having been replaced by WM Enterprise. <P1-S4>  The University of Warwick agreed in 2011 to purchase the shareholding of Coventry City Council. <P1-S5>  The acquisition was completed in 2012 and today the Science Park is wholly owned by the University of Warwick. <P1-S6>  UWSP currently covers four sites; the main campus abutting the University of Warwick, the Business Innovation Centre in Binley, Warwick Innovation Centre on Warwick Technology Park and Blythe Valley Innovation Centre near Solihull. <SEP> <P2-S0> Margaret Hilda Thatcher, Baroness Thatcher, {'1': ", '2': ", '3': ", '4': "} (née Roberts ; 13 October 1925 – 8 April 2013) was a British stateswoman who was Prime Minister of the United Kingdom from 1979 to 1990 and Leader of the Conservative Party from 1975 to 1990. <P2-S1>  She was the longest-serving British prime minister of the 20th century and the first woman to have been appointed. <P2-S2>  A Soviet journalist dubbed her the "Iron Lady", a nickname that became associated with her uncompromising politics and leadership style. <P2-S3>  As Prime Minister, she implemented policies that have come to be known as Thatcherism. <SEP> <P3-S0> The Prime Minister of the United Kingdom is the head of the Government of the United Kingdom, and chairs Cabinet meetings. <P3-S1>  There is no specific date when the office of Prime Minister first appeared, as the role was not created but rather evolved over a period of time. <P3-S2>  The term was used in the House of Commons in 1805 and it was certainly in parliamentary use by the 1880s, and in 1905 the post of Prime Minister was officially given recognition in the order of precedence. <P3-S3>  Modern historians generally consider Sir Robert Walpole, who led the government of Great Britain from 1721 to 1742, as the first Prime Minister. <P3-S4>  Walpole is also the longest-serving Prime Minister by this definition. <P3-S5>  However, Sir Henry Campbell-Bannerman was the first Prime Minister and Margaret Thatcher the longest-serving Prime Minister to have been officially referred to as such.
