Question: How long had Nomme Kalju been a team when Teever signed with them? Passage:After his contract expired in May 2012, Teever returned to Estonia and joined Nõmme Kalju's beach soccer team. He was also part of Estonian national team that played 2013 FIFA Beach Soccer World Cup qualification matches in Moscow in the beginning of July. Teever then signed a year-and-a-half long contract with Levadia and was instantly added to the UEFA Europa League squad. He also got offers from Finland and Germany, but decided to stay in Estonia so he could have better chance to return to the national team. On 19 July 2012, Teever made his debut for Levadia when he came on as a second-half substitute in a Europa League match against Cypriot side Anorthosis. He opened his goal scoring tally on his Meistriliiga debut on 23 July 2012, when his injury time free kick found the net against Tallinna Kalev.

Question: Were the Vuippens and Holy Romans allied? Passage:Gümmenen Castle, of which nothing remains, was built by either the Counts of Burgundy or the Dukes of Zähringen as part of the defenses along the Saane, along with Laupen Castle and Grasburg Castle. The castle was built to defend a bridge over the river. By 1391, a village (villa inferiori Dicti castri) had developed around the bridge. In 1259, Peter of Savoy made Gümmenen into an imperial fief and imperial castellans took over the castle and village. In 1282–83 King Rudolph I of Germany forced the Savoy castellan out and granted it to a Habsburg knight, Ulrich II of Maggenberg as a fief. Ulrich's heirs sold the castle, ferry and ford to Fribourg in 1319. Fribourg then granted the lands to the knights of Vuippens, who lost it back to either the Holy Roman Empire or Fribourg in 1325. The castle and village were besieged and destroyed in 1333 during Bern and Fribourg's first war over the Sense and Saane valleys, the Gümmenenkrieg. The peace treaty brokered in 1333 by Queen Agnes returned Gümmenen to Fribourg.

Question: Which team had more wins, the Reds or the Pirates? Passage:Holding off fierce competition from the Cincinnati Reds and Pittsburgh Pirates, the Cardinals clinched the division crown as each team won at least 90 games. The Cardinals finished the season with an NL-best 97–65 won–loss record. They opened the playoffs by defeating the Pirates in five games in the NL Division Series (NLDS). Advancing to their third straight National League Championship Series, they defeated the Los Angeles Dodgers in six games for their 19th NL pennant. Rookie Michael Wacha, who had nearly no-hit the Washington Nationals late in September, continued his dominance throughout the postseason as he allowed no runs against the Dodgers in 13 IP, earning the NLCS MVP. It was the second straight NLCS appearance to which manager Mike Matheny guided the Cardinals, who became the first manager to appear in an LCS in his first two seasons. Rookie closer Trevor Rosenthal extended a 20-inning postseason scoreless streak that started in the 2012 NLDS. The Cardinals met the Boston Red Sox in the World Series, only to lose the series in six games.
