Problem:Question: What modern day country did the Efe people populate? Passage 1:After playing club cricket in England and Ireland from 2004 to 2006. Northcote qualified to play for Italy though his Italian mother, with Northcote making his debut for Italy against Hong Kong in the 2007 World Cricket League Division Three which was held in Northern Territory, Australia. He played six matches during the tournament, scoring 91 runs at an average of 18.20, with a high score of 47. With the ball, he took 7 wickets at a bowling average of 19.00, with best figures of 3/26. He played for Italy in the 2008 European Cricket Championship Division One, but has relinquished the captaincy back to Scuderi. He made five appearances during the tournament. He was then selected as part of Italy's squad for the 2008 World Cricket League Division Four in Tanzania, making six appearances. He scored 234 runs during the tournament, at an average of 58.50, with a high score of 102 not out. This score was his only century of the tournament and came against Fiji. With the ball, he took 2 wickets at a bowling average of 35.00, with best figures of 2/19.
Passage 2:Much as was the case of the concurrent development of professional gridiron football, the Pittsburgh, Pennsylvania metropolitan area was one of the first areas to promote a professional ice hockey team. The Western Pennsylvania Hockey League began hiring professional players in 1902 and acted as a proam league. This league joined with teams in Michigan and Ontario to form the International Professional Hockey League in 1904, with Houghton, Michigan dentist Jack Gibson its founder. While this league had folded by 1907, it was the start of professional hockey. The United States would continue to see professional hockey with teams from the PCHL, beginning with the Portland Rosebuds, followed by a Seattle-based franchise a year later. When the Boston Bruins joined the NHL in 1924, the United States was finally represented in the league. It would continue to grow in the NHL until a peak in the 2000s (decade), when 24 of the NHL's 30 teams were in the United States (the loss of the Atlanta Thrashers to Winnipeg in 2011 reduced this number to 23; it returned to 24 American teams when the Vegas Golden Knights joined in 2017). The NHL will reach a higher peak when the Seattle expansion franchise joins the league in 2021-22 as the 25th American team. There are several other pro leagues in the US as well; as of 2019 these include the AHL, ECHL, SPHL, and FPHL. The AHL and ECHL are official minor leagues to the NHL, with the ECHL subservient to the AHL; the FPHL and SPHL operate as low-level independents.
Passage 3:In modern times, the creation of relatively simple dome-like structures has been documented among various indigenous peoples around the world. The wigwam was made by Native Americans using arched branches or poles covered with grass or hides. The Efe people of central Africa construct similar structures, using leaves as shingles. Another example is the igloo, a shelter built from blocks of compact snow and used by the Inuit people, among others. The Himba people of Namibia construct "desert igloos" of wattle and daub for use as temporary shelters at seasonal cattle camps, and as permanent homes by the poor. Extraordinarily thin domes of sun-baked clay 20 feet in diameter, 30 feet high, and nearly parabolic in curve, are known from Cameroon.
