Q: 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 PolishLithuanian Commonwealth. The PolishLithuanian Commonwealth was one of the largest and most populous countries in 16th- and 17th-century Europe.

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

Q: Question: Did the Gunpowder plot succeed in killing King James I? Passage:The early modern period in Britain saw religious conflict resulting from the Reformation and the recusancy that emerged in opposition to it. The Gunpowder Plot of 1605 was a failed attempt by a group of English Catholics to assassinate the Protestant King James I, and to blow up the Palace of Westminster, the English seat of government. Although the modern concept of religious terrorism, or indeed terrorism at all, had not yet come into use in the seventeenth century, David C. Rapoport and Lindsay Clutterbuck point out that the Plot, with its use of explosives, was an early precursor of nineteenth century anarchist terrorism. Sue Mahan and Pamala L. Griset classify the plot as an act of religious terrorism, writing that "Fawkes and his colleagues justified their actions in terms of religion." Peter Steinfels also characterizes this plot as a notable case of religious terrorism.

Q: Question: How old was the engineer when his invention was tested for Evel Knievel? Passage:ABC's Wide World of Sports was unwilling to pay the price Knievel wanted for the Snake River Canyon jump, so he hired boxing promoter Bob Arum's company, Top Rank Productions, to put the event on closed-circuit television and broadcast to movie Investors in the event took a substantial loss, including promoter Don E. Branker, as well as Vince McMahon of what was then called the World Wrestling Federation. Arum partnered with Invest West Sports, Shelly Saltman's company, to secure from Invest West Sports two things: first, the necessary financing for the jump, and second, the services of Saltman, long recognized as one of America's premier public relations and promotion men, to do publicity so that Knievel could concentrate on his jumps. Knievel hired subcontractor and aeronautical engineer Doug Malewicki to build him a rocket-powered cycle to jump across the Snake River, and called it the Skycycle X-1. Malwecki's creation was powered by a steam engine built by former Aerojet engineer Robert Truax. On April 15, 1972, the X-1 was launched to test the feasibility of the launching ramp. The decision was then made to have Truax build the Skycycle X-2 and have it take off and fly more like a rocket than a motorcycle.

A:
On April 15, 1972, the X-1 was launched to test the feasibility of the launching ramp
