Article: Modern-day Nigeria has been the site of numerous kingdoms and tribal states over the millennia. The modern state originated from British colonial rule beginning in the 19th century, and the merging of the Southern Nigeria Protectorate and Northern Nigeria Protectorate in 1914. The British set up administrative and legal structures whilst practising indirect rule through traditional chiefdoms. Nigeria became a formally independent federation in 1960, and plunged into a civil war from 1967 to 1970. It has since alternated between democratically-elected civilian governments and military dictatorships, until it achieved a stable democracy in 1999, with its 2011 presidential elections being viewed as the first to be conducted reasonably freely and fairly.

Question: When did a Nigerian Civil War begin?
Ans: 1967

Article: 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 m) 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.

Question: How many livery companies were in the meeting that founded the college?
Ans:
16
