Input: Consider Input: Question: Which stadium Cross played in holds more fans, Vale Park or Belle Vue? Passage:Cross began his career at Walsall, who finished 12th in the Third Division in 1966–67 under the stewardship of Ray Shaw. New boss Ron Lewin then took the "Saddlers" to a seventh-place finish in 1967–68. After a 13th-place finish in 1968–69, Bill Moore returned to lead Walsall to 12th place in 1969–70. Cross played just 12 league games in his four years at Fellows Park. He joined Gordon Lee's Port Vale in July 1970. He made his debut on 5 September, in a 1–0 win over Preston North End at Vale Park. He played 42 Third Division games in the 1970–71 season, and scored his first goal in the Football League on 2 January, in a 2–1 win over Doncaster Rovers at Belle Vue. He was an ever-present in the 1971–72 season, playing all 46 league and five cup games. He made 40 appearances in the 1972–73 season, and ended a series of 134 consecutive appearances from his debut in March 1973 when he wrenched his left knee. He recovered from this injury to play just two games in the 1973–74 campaign, but then he injured his knee ligaments in October 1973 and was out of action for 17 months. He managed to play just two games in the 1974–75 season, and was handed a free transfer in May 1975 by new manager Roy Sproson. He went on to play for Southern League side Nuneaton Borough. Upon his retirement as a player, he became a School of Excellence coach at Stoke City. He later went on to become a teacher for 25 years.

Input: Consider Input: Question: How many years were there between the death of Charlemagne and the first award of the Charlemagne Prize? Passage:The Charlemagne Prize (; full name originally Internationaler Karlspreis der Stadt Aachen, International Charlemagne Prize of the City of Aachen, since 1988 Internationaler Karlspreis zu Aachen, International Charlemagne Prize of Aachen) is a prize awarded for work done in the service of European unification. It has been awarded annually since 1950 by the German city of Aachen. It commemorates Charlemagne, ruler of the Frankish Empire and founder of what became the Holy Roman Empire, who resided and is buried in Aachen. Traditionally the award is given to the recipient on Ascension Day in a ceremony in the town hall of Aachen. In April 2008, the organisers of the Charlemagne Prize and the European Parliament jointly created a new European Charlemagne Youth Prize, which recognises contributions by young people towards the process of European integration. Patrons of the foundation are King Philippe of Belgium, King Felipe VI of Spain, and Henri, the Grand Duke of Luxembourg.

Input: Consider Input: Question: How wide is the body of water that separates the Eurasian and North American continents? Passage:The Russian Empire began its interest of the Pacific Northwest in the 18th century, initially curious if there was a land connection between the Eurasian and North American Continents. Two expeditions were led by Vitus Bering, with the findings proving the separation of two continents through the Bering Sea. Being the first European nation to chart much of what comprises the modern American state of Alaska, many locations retain Russian place names. The discovery of sizable fur bearing populations by Bering drew the attention of promyshlenniki previously engaged in the Siberian fur trade. Based out of the Siberian ports of Okhotsk or Petropavlovsk, fur trappers sailed and reported the location of land formations like the Aleutian Islands, Kodiak Island and portions of the Alaskan mainland. Relations with Native Alaskans was often terse due to the uncontrolled actions of particular promyshlenniki who killed and raped Indigenous on islands they trapped furs.
