Question: What year was Sheffield Wednesday founded? Passage:Armitage played for Sheffield Forge & Rolling Mills, Walkley Amateurs and Wadsley Bridge, before joining Sheffield Wednesday as an amateur in October 1914 after winning English Schools Shield with Sheffield.

He signed with Leeds United in August 1920, and scored the club's first ever goal in the Football League. He hit three goals in seven games in 1920–21, helping United to finish 14th in the Second Division. He scored eight goals in 32 games in 1921–22, as Leeds rose to eighth place.

Question: Was the Holy Roman Empire larger than Denmark-Norway at the time the Treaty of Speyer was signed? Passage:The Treaty of Speyer or Peace of Speyer was signed on May 23, 1544 between Denmark-Norway and the Holy Roman Empire during an Imperial Diet of the Holy Roman Empire in Speyer, Germany. Danish-Norwegian king Christian III had imposed heavy tolls on the Sound and two other channels between the North Sea and the Baltic sea, in an effort to end the Dutch dominance of trade in the Baltic region. Under pressure from Holy Roman Emperor Charles V, he agreed to exempt the Dutch ships from these tolls and give them free and unfettered access to the Baltic. In the treaty, Charles V also recognized Christian III as the rightful king of Denmark and Norway, and promised not to provide military support to his rival Christian II. The Treaty of Speyer dictated Christian III's foreign policy for the rest of his life. He kept Denmark-Norway at peace, refusing to involve the countries in Protestant-Catholic conflicts such as the Schmalkaldic War of 1546. The Dutch would continue to dominate Baltic trade for another two centuries.

Question: How long had the Russian Basketball Super League been in operation when BC UNICS was runner-up to CSKA? Passage:UNICS has gone a long way towards helping Russian basketball since the club was established in 1991. Between 1994 and 1997, UNICS secured a berth in Russia's first division, and then made a smashing debut, establishing itself among the top five teams in the country. UNICS had already played in European competitions in 1997, but the new millennium happened to be a turning point for the club. The team placed second to CSKA in the Russian Basketball Super League in 2001 and 2002, the year in which it also reached the Saporta Cup semifinals, losing against the Greek club Maroussi in the semifinals. UNICS' first title was the Russian Cup in March 2003, with an electrifying 81–82 overtime victory over CSKA. UNICS' fans did not have to wait long to see their team win a European title, too. Kazan hosted the FIBA Europe League final four, which was eventually named the FIBA EuroChallenge, in April 2004, and UNICS made sure of its opportunity. UNICS signed Saulius Štombergas, Eurelijus Žukauskas, and Chris Anstey, and then won its regular season group, and advanced to the final four, which was held on its own floor, and where the club was crowned the FIBA Europe League champions. The MVP of the tournament's final four, Martin Müürsepp, scored 22 points, in an 87–63 win over Maroussi, in the title game. By the 2005–06 season, UNICS went one level up, and made its ULEB Cup (later named EuroCup) debut, where they tied the best regular season record in the competition's history. However, things turned south quickly, as UNICS lost at home against Roma, for the only time all season, in the tournament's eighth finals’ second leg, and crashed out earlier than expected. UNICS got stronger for the next season, keeping the core group of the previous season's side, while adding Darjuš Lavrinovič to reunite with his twin brother Kšyštof Lavrinovič, in a twin-towers set full of talent. The team made it to the ULEB Cup semifinals, before losing to the eventual league champs Real Madrid. It also returned to the Russian League finals, losing against perennial champion CSKA.
