[Q]: Question: Why did the Nok culture die off about 200 AD on the Jos Plateau? Passage:The Nok culture thrived from approximately 1,500 BC to about 200 AD on the Jos Plateau in north and central Nigeria and produced life-sized terracotta figures that include human heads, human figures, and animals. Iron smelting furnaces at Taruga, a Nok site, date from around 600 BC. The Nok culture is thought to have begun smelting iron by 600-500 BC and possibly some centuries earlier. Kainji Dam excavations revealed iron-working by the 2nd century BC. Evidence of iron smelting has also been excavated at sites in the Nsukka region of southeast Nigeria in what is now Igboland: dating to 2,000 BC at the site of Lejja (Uzomaka 2009) and to 750 BC and at the site of Opi (Holl 2009). The transition from Neolithic times to the Iron Age apparently was achieved indigenously without intermediate bronze production. Others have suggested that the technology moved west from the Nile Valley, although the Iron Age in the Niger River valley and the forest region appears to predate the introduction of metallurgy in the upper savanna by more than 800 years. The earliest iron technology in West Africa has also been found to be contemporary with or predate that of the Nile valley and North Africa, and some archaeologists believe that iron metallurgy was likely developed independently in sub-Saharan West Africa.

[Q]: Question: Of the three cups University College Dublin competed in, which cup was established first? Passage:University College Dublin A.F.C. was founded in 1895 as the Catholic University Medical School Football Club. They began playing regular games the following year. A First XI played College games against other Universities and a Second XI entered outside competitions. The club was founder members of the Leinster Junior League in 1896 and reached the semi-finals of the Leinster Senior Cup in 1897. The club became University College Dublin when the new University annexed the Medical school in 1908. UCD won the inaugural Intervarsities competition, the Collingwood Cup, in 1914 and added the Irish Intermediate Cup the following year beating Portadown 2–1 in a replayed final. When the Irish Free State was formed in 1921 and the new Football Association of Ireland was formed, UCD participated in the Preliminary round against fellow non-League team Shamrock Rovers in November 1921. The game took place in Windy Arbour and the Hoops won 6–2. UCD were invited to join the League of Ireland in 1922, but had to turn it down on the basis of not being able to field a team in the League of Ireland Shield in September as the Academic year didn't commence until October. In 1945 they won the FAI Intermediate Cup when UCD beat fellow future League of Ireland members Cobh Ramblers 4–2 in the final. UCD appeared in the FAI Cup in the 1930s, 1940s and 1950s, their final appearance as a non-League outfit coming in 1957 when Cork Athletic beat UCD 4–2 in the Mardyke.
