[EX Q]: Question: When did the pitcher who Bay hit a grand slam off of in September retire? Passage:Bay got off to a slow start to the 2012 season, finishing spring training with no home runs or RBI, and his regular season, which was derailed further by a broken rib suffered while making a diving catch in the April 23 game against the San Francisco Giants. When Bay returned from the DL on June 8, 2012 against the New York Yankees, he went 0-for-3 with one strikeout. He continued to go 0-for-16 in his return from the DL through June 12, before hitting a single on June 13 against the Tampa Bay Rays. In a home game against the Cincinnati Reds on June 15, Bay left the game in the second inning after crashing into the left field wall and suffering a concussion while attempting to catch a fly ball by Jay Bruce that became an inside-the-park home run. He was subsequently placed on the DL again, and returned again on July 17 against the Washington Nationals. On September 2, Bay hit a grand slam off of Miami Marlins pitcher Mark Buehrle in the first inning of a 52 Mets win. Bay also hit a home run off of Buehrle on September 22 in a 43 Mets win. Bay finished the 2012 season with a .165 batting average, 8 home runs and 20 RBI.

[EX Q]: Question: Were the Vuippens and Holy Romans allied? Passage:Gummenen Castle, of which nothing remains, was built by either the Counts of Burgundy or the Dukes of Zahringen 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 Gummenen into an imperial fief and imperial castellans took over the castle and village. In 128283 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 Gummenenkrieg. The peace treaty brokered in 1333 by Queen Agnes returned Gummenen to Fribourg.

[EX Q]: Question: How long did the financial period last that delayed work on the park? Passage:A $2.5 million bond issue passed in 1922 for a stadium conceived by Burnham. Designed by architects Holabird & Roche and named Soldier Field for the veterans of World War I, cost overruns required another bond issue in 1926. By 1924, the breakwater wall stretched from 14th to 55th Streets. In 1926, Soldier Field and a portion of Lake Shore Drive were opened. Landfilling extended from 23rd Street to 56th Street; however, Promontory Point was not complete, prompting complaints regarding garbage, blowing sand and odors. Throughout the 1920s and 1930s, landfill efforts continued to fill in Burnham Park and the adjacent Northerly Island. The South Development was named for Daniel Burnham on January 14, 1927, and support increased for a world's fair in the park. Construction was completed on Lake Shore Drive, with northbound lanes named for Leif Erikson, and southbound lanes for Christopher Columbus. In 1929, construction of the park at Promontory Point began. The Great Depression delayed work and prevented construction of nearshore islands. Burnham Park was chosen for the site of the Century of Progress world's fair and a yacht basin was built south of 51st Street.
