Question: In Bolivia, a 62% majority of residents over the age of 15 self-identify as belonging to an indigenous people, while another 3.7% grew up with an indigenous mother tongue yet do not self-identify as indigenous. Including both of these categories, and children under 15, some 66.4% of Bolivia's population was registered as indigenous in the 2001 Census. The largest indigenous ethnic groups are: Quechua, about 2.5 million people; Aymara, 2.0 million; Chiquitano, 181,000; Guaraní, 126,000; and Mojeño, 69,000. Some 124,000 belong to smaller indigenous groups. The Constitution of Bolivia, enacted in 2009, recognizes 36 cultures, each with its own language, as part of a plurinational state. Some groups, including CONAMAQ (the National Council of Ayllus and Markas of Qullasuyu) draw ethnic boundaries within the Quechua- and Aymara-speaking population, resulting in a total of fifty indigenous peoples native to Bolivia.
Is there an answer to this question: In the 2001 census, how much of Bolivia's population was labeled as being indigenous?

Answer: 66.4%


Question: The 1960s and 1970s saw an acceleration in the decolonisation of Africa and the Caribbean. Over 20 countries gained independence from Britain as part of a planned transition to self-government. In 1965, however, the Rhodesian Prime Minister, Ian Smith, in opposition to moves toward majority rule, declared unilateral independence from Britain while still expressing "loyalty and devotion" to Elizabeth. Although the Queen dismissed him in a formal declaration, and the international community applied sanctions against Rhodesia, his regime survived for over a decade. As Britain's ties to its former empire weakened, the British government sought entry to the European Community, a goal it achieved in 1973.
Is there an answer to this question: In what year did Rhodesia cease to exist?

Answer: unanswerable


Question: City and Guilds College was founded in 1876 from a meeting of 16 of the City of London's livery companies for the Advancement of Technical Education (CGLI), which aimed to improve the training of craftsmen, technicians, technologists, and engineers. The two main objectives were to create a Central Institution in London and to conduct a system of qualifying examinations in technical subjects. Faced with their continuing inability to find a substantial site, the Companies were eventually persuaded by the Secretary of the Science and Art Department, General Sir John Donnelly (who was also a Royal Engineer) to found their institution on the eighty-seven acre (350,000 m²) site at South Kensington bought by the 1851 Exhibition Commissioners (for GBP 342,500) for 'purposes of art and science' in perpetuity. The latter two colleges were incorporated by Royal Charter into the Imperial College of Science and Technology and the CGLI Central Technical College was renamed the City and Guilds College in 1907, but not incorporated into Imperial College until 1910.
Is there an answer to this question: Other than conducting a system of qualifying examinations, what was the other main objective of the meeting of CGLI?

Answer: to create a Central Institution in London


Question: In quantum mechanics and quantum field theory, the vacuum is defined as the state (that is, the solution to the equations of the theory) with the lowest possible energy (the ground state of the Hilbert space). In quantum electrodynamics this vacuum is referred to as 'QED vacuum' to distinguish it from the vacuum of quantum chromodynamics, denoted as QCD vacuum. QED vacuum is a state with no matter particles (hence the name), and also no photons. As described above, this state is impossible to achieve experimentally. (Even if every matter particle could somehow be removed from a volume, it would be impossible to eliminate all the blackbody photons.) Nonetheless, it provides a good model for realizable vacuum, and agrees with a number of experimental observations as described next.
Is there an answer to this question: What is a blackbody photon referred to in quantum mechanics?

Answer:
unanswerable
