Problem:Question: How long is the river along which the Polanie remained in situ? Passage 1:KJ Noons is hapa kanaka, hapa haole—mixed ethnicity of native Hawaiian (from his mother's side) and European-American (from his father's side). Born and raised in Kailua-Kona, Hawaii, Noons comes from a family history of fighting. His father Karl was a professional kickboxer and was a top contender during the time he fought. Karl's passion for fighting and competing in combat sports influenced him to introduce his son to martial arts at a young age. At the age of five, Noons started training in Kenpō Karate. Often getting disqualified for fighting too hard in karate tournaments, Noons eventually started training in boxing and Muay Thai at the age of eight out of interest for full contact fighting. Noons competed as an amateur fighter and became the first student in the state of Hawaii to earn a junior black belt under Ed Parker at the age of 11. During his high school years, Noons moved to Houston, Texas due to the location of his father's job. While continuing to compete as a fighter, he also started playing football at Clements High School. At age 17, Noons won the ISKA Super Middleweight International Championship as an amateur in Sanshou. After winning the title and graduating from Clements High School, K.J. decided to pursue a career in combat sports, rather than go to college and continue with football.
 Passage 2:The Poles are the most numerous of the West Slavs and occupy what some believe to be the original homeland of the Slavic peoples. While other groups migrated, the Polanie remained in situ along the Vistula, from the river's sources to its estuary at the Baltic Sea. There is no other European nation centred to such an extent on one river. The establishment of a Polish state is often identified with the adoption of Christianity by Mieszko I in 966 CE (see Baptism of Poland), when the state covered territory similar to that of present-day Poland. In 1025 CE, Poland became a kingdom. In 1569, Poland cemented a long association with the Grand Duchy of Lithuania by signing the Union of Lublin, forming the Polish–Lithuanian Commonwealth. The Polish–Lithuanian Commonwealth was one of the largest and most populous countries in 16th- and 17th-century Europe.
 Passage 3:On January 28, 1986, the NASA Space Shuttle orbiter undertaking mission STS-51-L and the tenth flight of (OV-099) broke apart 73 seconds into its flight, killing all seven crew members: five NASA astronauts, one payload specialist, and a civilian school teacher. The spacecraft disintegrated over the Atlantic Ocean, off the coast of Cape Canaveral, Florida, at 11:39a.m. EST (16:39 UTC). The disintegration of the vehicle began after a joint in its right solid rocket booster (SRB) failed at liftoff. The failure was caused by the failure of O-ring seals used in the joint that were not designed to handle the unusually cold conditions that existed at this launch. The seals' failure caused a breach in the SRB joint, allowing pressurized burning gas from within the solid rocket motor to reach the outside and impinge upon the adjacent SRB aft field joint attachment hardware and external fuel tank. This led to the separation of the right-hand SRB's aft field joint attachment and the structural failure of the external tank. Aerodynamic forces broke up the orbiter.
