full_context: Document 1: Oklahoma City: Oklahoma City has a major park in each quadrant of the city, going back to the first parks masterplan. Will Rogers Park, Lincoln Park, Trosper Park, and Woodson Park were once connected by the Grand Boulevard loop, some sections of which no longer exist. Martin Park Nature Center is a natural habitat in far northwest Oklahoma City. Will Rogers Park is home to the Lycan Conservatory, the Rose Garden, and Butterfly Garden, all built in the WPA era. Oklahoma City is home to the American Banjo Museum, which houses a large collection of highly decorated banjos from the early 20th century and exhibits on the history of the banjo and its place in American history. Concerts and lectures are also held there.
Document 2: Roy Hinson: Roy Hinson (born May 2, 1961) is a retired American professional basketball player who was selected by the Cleveland Cavaliers in the first round (20th pick overall) of the 1983 NBA draft. Hinson attended Franklin High School in Franklin Township, New Jersey. He then played his college career at Rutgers University in nearby New Brunswick.

Document 3: Palermo: Today both the Papireto river and the Kemonia are covered up by buildings. However, the shape of the former watercourses can still be recognised today, because the streets that were built on them follow their shapes. Today the only waterway not drained yet is the Oreto river that divides the downtown of the city from the western uptown and the industrial districts. In the basins there were, though, many seasonal torrents that helped formed swampy plains, reclaimed during history; a good example of which can be found in the borough of Mondello.
Document 4: NBA high school draftees: In the early years of the NBA draft, a player had to finish his four - year college eligibility to be eligible for selection. Reggie Harding, who had graduated from high school but did not enroll in a college, became the first player drafted out of high school when the Detroit Pistons selected him in the fourth round of the 1962 draft. However, the NBA rules at that time prohibited a high school player to play in the league until one year after his high school class graduated. Thus, he spent a year playing in a minor basketball league before he was drafted again in the 1963 draft by the Pistons. He finally entered the league in the 1963 -- 64 season and played four seasons in the NBA and American Basketball Association (ABA).
Document 5: Oklahoma City: The city is roughly bisected by the North Canadian River (recently renamed the Oklahoma River inside city limits). The North Canadian once had sufficient flow to flood every year, wreaking destruction on surrounding areas, including the central business district and the original Oklahoma City Zoo. In the 1940s, a dam was built on the river to manage the flood control and reduced its level. In the 1990s, as part of the citywide revitalization project known as MAPS, the city built a series of low-water dams, returning water to the portion of the river flowing near downtown. The city has three large lakes: Lake Hefner and Lake Overholser, in the northwestern quarter of the city; and the largest, Lake Stanley Draper, in the sparsely populated far southeast portion of the city.
Document 6: Lake Texcoco: Tenochtitlan was founded on an islet in the western part of the lake in the year 1325. Around it, the Aztecs created a large artificial island using a system similar to the creation of chinampas. To overcome the problems of drinking water, the Aztecs built a system of dams to separate the salty waters of the lake from the rain water of the effluents. It also permitted them to control the level of the lake. The city also had an inner system of channels that helped to control the water.
Document 7: Leroy Combs: Edwin Leroy Combs (born January 1, 1961 in Oklahoma City, Oklahoma) is a retired professional basketball small forward who spent one season in the National Basketball Association (NBA) as a member of the Indiana Pacers during the 1983–84 season.

Document 8: Jerry Newsom: Jerry Newsom was selected as the 74th overall pick in the 1968 NBA Draft by the Boston Celtics; he was also drafted by the Indiana Pacers in the 1968 ABA Draft, in the 6th-10th rounds. He did not appear in a professional game but went on to a successful business career in his hometown. He obtained his referee license in order to remain involved in basketball and became a highly respected IHSAA referee.
Document 9: Dammam: Having been built from the ground up, the Dammam Area was designed from the outset on the principles of modern urban planning. Residential areas are separate from commercial sections, roads are broad and straight and buildings conform to a master plan. One of the main features of the development of the area is land reclamation. Vast stretches of the shallow Persian Gulf waters have been filled, with hotels and office buildings occupying what were once marshes. Water for household, urban and industrial use is provided by desalination plants that supply approximately seven million cubic feet of treated water to the area each day. The availability of water underpins the urban and industrial growth of the Dammam Area, and provisions have been made for expanding existing desalination facilities to meet future growth.
Document 10: Oklahoma City: Walking trails line Lake Hefner and Lake Overholser in the northwest part of the city and downtown at the canal and the Oklahoma River. The majority of the east shore area is taken up by parks and trails, including a new leashless dog park and the postwar-era Stars and Stripes Park. Lake Stanley Draper is the city's largest and most remote lake.
Document 11: 1984 NBA draft: The Houston Rockets used their first pick to draft Akeem Olajuwon, a junior center from the University of Houston. The Nigerian - born Olajuwon became the second foreign - born player to be drafted first overall, after Mychal Thompson from the Bahamas in 1978. The Portland Trail Blazers used the second overall pick to draft Sam Bowie from the University of Kentucky. The Chicago Bulls used the third pick to draft Naismith and Wooden College Player of the Year Michael Jordan from the University of North Carolina. Jordan went on to win the Rookie of the Year Award and was also selected to the All - NBA Second Team in his rookie season. Jordan's teammate at North Carolina, Sam Perkins, was drafted fourth by the Dallas Mavericks. Charles Barkley, a junior forward from Auburn University, was drafted fifth by the Philadelphia 76ers.
Document 12: Oklahoma City: In 1993, the city passed a massive redevelopment package known as the Metropolitan Area Projects (MAPS), intended to rebuild the city's core with civic projects to establish more activities and life to downtown. The city added a new baseball park; central library; renovations to the civic center, convention center and fairgrounds; and a water canal in the Bricktown entertainment district. Water taxis transport passengers within the district, adding color and activity along the canal. MAPS has become one of the most successful public-private partnerships undertaken in the U.S., exceeding $3 billion in private investment as of 2010. As a result of MAPS, the population living in downtown housing has exponentially increased, together with demand for additional residential and retail amenities, such as grocery, services, and shops.
Document 13: Bill Combs: Billy Burk Combs (August 22, 1918 - February 19, 1945) was an All-American collegiate wrestler at the University of Michigan (1939–41) who was killed in the invasion of Iwo Jima during World War II. A native of Tulsa, Oklahoma, Combs enrolled at the University of Michigan and competed for the Michigan wrestling teams coached by Oklahoma native Cliff Keen.

Document 15: Mexico City: Originally much of the valley laid beneath the waters of Lake Texcoco, a system of interconnected salt and freshwater lakes. The Aztecs built dikes to separate the fresh water used to raise crops in chinampas and to prevent recurrent floods. These dikes were destroyed during the siege of Tenochtitlan, and during colonial times the Spanish regularly drained the lake to prevent floods. Only a small section of the original lake remains, located outside the Federal District, in the municipality of Atenco, State of Mexico.
