Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as 'a' for Yes or 'b' for No.

[EX 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.

[EX Q]: Question: Did the player with a contract ending in 2008 renew with the same team? Passage:Most of the players have contracts beyond this end of season, but Deco, an important player, has his contract ending in 2008. The captain is still Carles Puyol, who is from Barcelona's youth system, plays in the first squad since 1999 and currently is the player with the most appearances (268). Currently, the highest scorer is Ronaldinho, with 80 goals. Also Ronaldinho, from August of this year, has a European passport. On mid-October, Samuel Eto'o received Spanish nationality, making him an EU player. The only non-EU player is Yaya Toure. Because Spain ratified the Cotonou Agreement in 2007, however, Toure is now considered an EU player, as his native country of Ivory Coast is a signatory to that agreement, and the 2003 Kolpak ruling extended the Bosman ruling to nations with an associate trading relationship with the EU.
