Question: Question: How long is the river along which the Polanie remained in situ? Passage: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.


Answer: While other groups migrated, the Polanie remained in situ along the Vistula, from the river's sources to its estuary at the Baltic Sea


Question: Question: How many people did Tartu Observatory employ the year Pustõlnik first began working there? Passage:A native of the Ukrainian port city of Odessa (a part of the Soviet Union until 1991), Izold Pustõlnik graduated cum laude from Odessa University in 1960 and received his Ph.D. from the University of Tartu in 1969 and his D.Sc. from Saint Petersburg State University in 1994. From the age of 27 in 1965 until his death forty-three years later, he was on the staff of Tartu Observatory where, as a research associate (promoted to senior research associate in 2000), he worked on the physics of close binary systems, theory of stellar atmospheres, interstellar medium, archaeoastronomy and history of astronomy.
