Input: Article: Remodelling of the structure began in 1762. After his accession to the throne in 1820, King George IV continued the renovation with the idea in mind of a small, comfortable home. While the work was in progress, in 1826, the King decided to modify the house into a palace with the help of his architect John Nash. Some furnishings were transferred from Carlton House, and others had been bought in France after the French Revolution. The external facade was designed keeping in mind the French neo-classical influence preferred by George IV. The cost of the renovations grew dramatically, and by 1829 the extravagance of Nash's designs resulted in his removal as architect. On the death of George IV in 1830, his younger brother King William IV hired Edward Blore to finish the work. At one stage, William considered converting the palace into the new Houses of Parliament, after the destruction of the Palace of Westminster by fire in 1834.

Input: Article: METRO Transit is the city's public transit company. The main transfer terminal is located downtown at NW 5th Street and Hudson Avenue. METRO Transit maintains limited coverage of the city's main street grid using a hub-and-spoke system from the main terminal, making many journeys impractical due to the rather small number of bus routes offered and that most trips require a transfer downtown. The city has recognized that transit as a major issue for the rapidly growing and urbanizing city and has initiated several studies in recent times to improve upon the existing bus system starting with a plan known as the Fixed Guideway Study. This study identified several potential commuter transit routes from the suburbs into downtown OKC as well as feeder-line bus and/or rail routes throughout the city.

Input: Article: As the 20th century came to a close, Gaddafi increasingly rejected Arab nationalism, frustrated by the failure of his Pan-Arab ideals; instead he turned to Pan-Africanism, emphasising Libya's African identity. From 1997 to 2000, Libya initiated cooperative agreements or bilateral aid arrangements with 10 African states, and in 1999 joined the Community of Sahel-Saharan States. In June 1999, Gaddafi visited Mandela in South Africa, and the following month attended the OAU summit in Algiers, calling for greater political and economic integration across the continent and advocating the foundation of a United States of Africa. He became one of the founders of the African Union (AU), initiated in July 2002 to replace the OAU; at the opening ceremonies, he proclaimed that African states should reject conditional aid from the developed world, a direct contrast to the message of South African President Thabo Mbeki. At the third AU summit, held in Libya in July 2005, he called for a greater level of integration, advocating a single AU passport, a common defence system and a single currency, utilising the slogan: "The United States of Africa is the hope." In June 2005, Libya joined the Common Market for Eastern and Southern Africa (COMESA), and in August 2008 Gaddafi was proclaimed "King of Kings" by an assembled committee of traditional African leaders. On 1 February 2009, his "coronation ceremony" was held in Addis Ababa, Ethiopia, coinciding with Gaddafi's election as AU chairman for a year.
