Article: Other types of lossy compressors, such as the linear predictive coding (LPC) used with speech, are source-based coders. These coders use a model of the sound's generator (such as the human vocal tract with LPC) to whiten the audio signal (i.e., flatten its spectrum) before quantization. LPC may be thought of as a basic perceptual coding technique: reconstruction of an audio signal using a linear predictor shapes the coder's quantization noise into the spectrum of the target signal, partially masking it.

Question: What uses a model of the sound's generator?
Ans: source-based coders

Article: The era saw Libya's return to the international arena. In 1999, Libya began secret talks with the British government to normalise relations. In 2001, Gaddafi condemned the September 11 attacks on the U.S. by al-Qaeda, expressing sympathy with the victims and calling for Libyan involvement in the War on Terror against militant Islamism. His government continued suppressing domestic Islamism, at the same time as Gaddafi called for the wider application of sharia law. Libya also cemented connections with China and North Korea, being visited by Chinese President Jiang Zemin in April 2002. Influenced by the events of the Iraq War, in December 2003, Libya renounced its possession of weapons of mass destruction, decommissioning its chemical and nuclear weapons programs. Relations with the U.S. improved as a result, while UK Prime Minister Tony Blair met with Gaddafi in the Libyan desert in March 2004. The following month, Gaddafi travelled to the headquarters of the European Union (EU) in Brussels, signifying improved relations between Libya and the EU, the latter ending its remaining sanctions in October. In October 2010, the EU paid Libya 50 million to stop African migrants passing into Europe; Gaddafi encouraged the move, saying that it was necessary to prevent the loss of European cultural identity to a new "Black Europe". Removed from the U.S. list of state sponsors of terrorism in 2006, Gaddafi nevertheless continued his anti-western rhetoric, and at the Second Africa-South America Summit in Venezuela in September 2009, joined Venezuelan President Hugo Chavez in calling for an "anti-imperialist" front across Africa and Latin America. Gaddafi proposed the establishment of a South Atlantic Treaty Organization to rival NATO. That month he also addressed the United Nations General Assembly in New York for the first time, using it to condemn "western aggression". In Spring 2010, Gaddafi proclaimed jihad against Switzerland after Swiss police accused two of his family members of criminal activity in the country, resulting in the breakdown of bilateral relations.

Question: What world leader notably visited Libya in 2002?
Ans: Jiang Zemin

Article: The pagan Slavic populations were Christianized between the 6th and 10th centuries. Orthodox Christianity is predominant in the East and South Slavs, while Roman Catholicism is predominant in West Slavs and the western South Slavs. The religious borders are largely comparable to the EastWest Schism which began in the 11th century. The majority of contemporary Slavic populations who profess a religion are Orthodox, followed by Catholic, while a small minority are Protestant. There are minor Slavic Muslim groups. Religious delineations by nationality can be very sharp; usually in the Slavic ethnic groups the vast majority of religious people share the same religion. Some Slavs are atheist or agnostic: only 19% of Czechs professed belief in god/s in the 2005 Eurobarometer survey.

Question: When did the East-West Schism begin?
Ans:
11th century
