PROBLEM: 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.


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

PROBLEM: Question: What team did Gary Tallon play for the year Boulding turned professional? Passage:Boulding maintained his links with football and trained with Doncaster Rovers, and in 1998 he joined non-league Hallam near his home in Sheffield. His form at Hallam attracted the interest of a number of league clubs, and Boulding was offered a trial by Mansfield Town. He was given a contract by the Division Three side and turned professional in 1999, which brought an end to his tennis career. He made his debut with Mansfield in a League Cup game against Nottingham Forest on 11 August 1999 as a late substitute for Gary Tallon, before his first league game came three days later against Cheltenham Town. He had to wait until his 12th game as a professional to register his first goal when he scored in a 2–1 victory over Shrewsbury Town on 23 October. He eventually finished his first season with six goals with Mansfield coming 17th but 17 points above Carlisle United, the only side to be relegated out of The Football League.


SOLUTION: He was given a contract by the Division Three side and turned professional in 1999, which brought an end to his tennis career

PROBLEM: Question: In what year did Jackie Jensen with Most Valuable Player? Passage:Jack Eugene Jensen (March 9, 1927 – July 14, 1982) was an American right fielder in Major League Baseball who played for three American League (AL) teams from 1950 to 1961, most notably the Boston Red Sox. He was named the AL's Most Valuable Player (MVP) in after hitting 35 home runs and leading the league with 122 runs batted in (RBIs); he also led the league in RBIs two other years, and in triples and stolen bases once each. Respected for his throwing arm, he won a Gold Glove Award and led the AL in assists and double plays twice each. He retired in his early thirties as major-league baseball expanded westward, due to an intense fear of flying. After being a two-sport star in college, Jensen was the first man to play in the Rose Bowl, the World Series, and the MLB All-Star Game.
