Question: 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.

Question: Question: How many years after the Venetian Republic was established was Palmanova founded? Passage:On 7 October 1593, the superintendent of the Venetian Republic founded a revolutionary new kind of settlement: Palmanova. The city’s founding date commemorated the victory of the Christian forces (supplied primarily by the Italian states and the Spanish kingdom) over the Ottoman Turks in the Battle of Lepanto in 1571, during the War of Cyprus. Also honored on 7 October was Saint Justina, chosen as the city's patron saint. Using all the latest military innovations of the 16th century, this small town was a fortress in the shape of a nine-pointed star, designed by Vincenzo Scamozzi. Between the points of the star, ramparts protruded so that the points could defend each other. A moat surrounded the town, and three large, guarded gates allowed entry. The construction of the first circle, with a total circumference of , took 30 years. Marcantonio Barbaro headed a group of Venetian noblemen in charge of building the town, Marcantonio Martinego was in charge of construction, and Giulio Savorgnan acted as an adviser. A second phase of construction took place between 1658 and 1690, and the outer line of fortifications was completed between 1806 and 1813 under the Napoleonic domination. The final fortress consists of: 9 ravelins, 9 bastions, 9 lunettes, and 18 cavaliers.
