Problem: Kabuls population is estimated to have been about 10,000 in 1700, 65,000 by 1878, and 120,000 by 1940. More recently, the population was around 500,000 in 1979, whilst another source claims 337,715 as of 1976. This figure rose to about 1.5 million by 1988, before dramatically dropping in the 1990s. Kabul became one of the fastest growing cities in the world, with its population growing fourfold from 2001 to 2014. This was partly due to the return of refugees after the fall of the Taliban regime, and partly due to Afghans moving from other provinces mainly due to war between Taliban insurgents and Afghan government forces in their native areas as well as looking for labor. This resulting rapid urbanization mean that many residents today live in informal settlements. Shanty mud-brick homes on the mountainsides and steep hills have been built by them and these are usually poverty-stricken, not connected to the water and electricity grid. Although the settlements are illegal, they have been tolerated by authorities. In 2017 Kabul Municipality started a project to paint the homes in these settlements in bright colors in an effort to "cheer up" residents.

How many years did it take for the population to grow four-fold?
Answer: 13

Problem: The 2011 Thailand Country Report provides population numbers for mountain peoples (hill tribes) and ethnic communities in the Northeast and is explicit about its main reliance on the Mahidol University Ethnolinguistic Maps of Thailand data. Thus, though over 3.288 million people in the Northeast alone could not be categorised, the population and percentages of other ethnic communities circa 1997 are known for all of Thailand and constitute minimum populations. In descending order, the largest (equal to or greater than 400,000) are a) 15,080,000 Lao (24.9 percent) consisting of the Thai Lao (14 million) and other smaller Lao groups, namely the Thai Loei (400–500,000), Lao Lom (350,000), Lao Wiang/Klang (200,000), Lao Khrang (90,000), Lao Ngaew (30,000), and Lao Ti (10,000; b) six million Khon Muang (9.9 percent, also called Northern Thais); c) 4.5 million Pak Tai (7.5 percent, also called Southern Thais); d) 1.4 million Khmer Leu (2.3 percent, also called Northern Khmer); e) 900,000 Malay (1.5%); f) 500,000 Ngaw (0.8 percent); g) 470,000 Phu Thai (0.8 percent); h) 400,000 Kuy/Kuay (also known as Suay) (0.7 percent), and i) 350,000 Karen (0.6 percent). Thai Chinese, those of significant Chinese heritage, are 14% of the population, while Thais with partial Chinese ancestry comprise up to 40% of the population. Thai Malays represent 3% of the population, with the remainder consisting of Mon people, Khmers and various "Hill tribe (Thailand)". The countrys official language is Thai language and the primary religion is Theravada Buddhism, which is practised by around 95% of the population.

How many percent of people were not Kuy/Kuay?
Answer: 99.3

Problem: In 1905, the Qing sent Zhao Erfeng to Tibet to retaliate against rebellions. By 1908, Zhao was appointed imperial resident in Lhasa. Zhao was beheaded in December 1911 by pro-Republican forces. The bulk of the area that was historically known as Kham was now claimed to be the Xikang Administrative District, created by the Republican revolutionaries. By the end of 1912, the last Manchu troops were forced out of Tibet through India. Thubten Gyatso, the 13th Dalai Lama, returned to Tibet in January 1913 from Sikkim, where he had been residing. When the new ROC government apologised for the actions of the Qing and offered to restore the Dalai Lama to his former position, he replied that he was not interested in Chinese ranks, that Tibet had never been subordinated to China, that Tibet was an independent country, and that he was assuming the spiritual and political leadership of Tibet. Because of this, many have read this reply as a formal declaration of independence. The Chinese side ignored the response, and Tibet had thirty years free of interference from China.

Where did the Manchu troops go first, Tibet or India?
Answer:
Tibet
