[Q]: Question: What was the previous episode that the 2005 one where the tenth doctor was introduced followed? Passage:The regeneration of the Ninth Doctor into the Tenth at the end of "The Parting of the Ways" (2005) used computer effects to morph Christopher Eccleston into David Tennant. In the episode of Doctor Who Confidential accompanying the episode "Utopia" (2007), where the same effect is used for the Master's regeneration, it is stated that the production team decided that this would be a common effect for all future Time Lord regenerations, rather than each regeneration being designed uniquely at the whim of the individual director. This style of transition is seen again in "The Stolen Earth"/"Journey's End" (2008) both when the Doctor undergoes an aborted regeneration, and when his hand spawns a clone in the second part; in The End of Time (2010) during which Matt Smith took over the role as the Eleventh Doctor; in "The Impossible Astronaut" when the Doctor is shot twice and seemingly killed; in "Day of the Moon" when a young girl regenerates; and in "Let's Kill Hitler" when Mels (Nina Toussaint-White) is shot and regenerates into River Song (Alex Kingston). "The Night of the Doctor" and "The Day of the Doctor" subsequently use the effect to show the Eighth Doctor and War Doctor's regenerations respectively. The Eighth Doctor's regeneration into the War Doctor uses steady beams of light as opposed to the flame effect used for other revived series regenerations. In the Series 10 episode "The Lie of the Land", the Twelfth Doctor fakes a regeneration as part of a plan to test if Bill still has free will. The effect used is consistent with the one used in the modern series, with the Doctor's hands glowing and emitting regeneration energy before he enters full regeneration. However, as the regeneration was not real, it did not use up a regeneration and the Doctor did not change bodies.

[Q]: Question: Which country's air force was garrisoned at Taichung until 1955? Passage:Taichung International Airport was constructed during the era of Japanese rule and was named . The United States Air Force (USAF) had been garrisoning the base with two fighter squadrons until the Sino-American Mutual Defense Treaty came into force on March 3, 1955. The airport then expanded in 1954 according to the Sino-American Mutual Defense Treaty, and later renamed Ching Chuan Kang Air Base (CCK) in memory of General Qiu Qingquan. In 1966 the American Air Force established a joint forces air-base at CCK. It was the largest air force base in the Far East at the time, allowing Boeing B-52 Stratofortress bombers to land. During the Vietnam War, CCK became a depot for the USAF. The US Military used CCK and Shuinan Airport to run many of its long-distance Vietnam, Cambodia and Laotian bombing, scouting and cargo transport runs during the Vietnam War era. This base was shut down and most American facilities were removed after U.S. established diplomatic relations with the China in 1979.

[Q]: Question: Which of the boroughs of London that about a quarter of the Chinese population living in the UK has the highest total population? Passage:By the late 1960s, the Chinese restaurants and shops around Gerrard Street, Lisle Street, and Little Newport Street had evolved into "Tong Yan Kai", otherwise known as Chinatown. The general public developed a taste for Chinese food during the postwar restaurant boom. In 1963, the Zhongshan Workers' Club opened in the West End, showing films and running classes. The first Chinese New Year celebrations were held in Gerrard Street. The Overseas Chinese Service opened the first specialised agency to assist the Chinese in dealing with the host society by offering a translation and interpreting service. In the 1970s and 1980s, many ethnic Chinese who had settled in Vietnam for generations were forced to leave as "boat people" following the Vietnam War. Many settled in Lewisham, Lambeth, and Hackney, as well as elsewhere in the UK. The 1980s and 1990s saw a migration of academics and professionals from Chinatown to the suburbs of Croydon and Colindale. Since the 1980s, London's Chinatown has been transformed by Westminster City Council to become a major tourist attraction and a cultural focal point of the Chinese community in London. Today over 100,000 Chinese people live in London, and are more evenly dispersed throughout the city and its boroughs. Roughly a quarter of the Chinese population of the United Kingdom now live in London, mainly in the boroughs of Barnet, Haringey, Waltham Forest, Hackney, Southwark and Westminster. Mare Street in Hackney is the hub of a small Vietnamese community. The principal languages of the London Chinese community are Cantonese and Hakka (from the New Territories, Hong Kong, and Vietnam). There are also some speakers of Hokkien, Teochew and Hainanese. The Chinese from the People's Republic of China, Taiwan, and Singapore tend to speak Mandarin (or Putonghua). A large network of Chinese schools and community centres offers support and a means of passing on cultural identity from one generation to the next.
