Question: Was the stadium where Swann's most notable performance occurred built before 1990? Passage:For 2003, he signed with the Baltimore Orioles and again spent a few games in the majors. His most notable performance as a major leaguer occurred at Camden Yards on September 18, 2003. An attempt to avoid Hurricane Isabel by changing the game's start time from 7:05 pm (ET) to 12:35 pm proved futile as the contest was played entirely in a downpour. With the score tied at one, Swann opened the bottom of the fifth inning with a double off Mike Mussina. When Brian Roberts hit a one-out single to left field, Orioles third-base coach Tom Trebelhorn had initially waved Swann home. He abruptly put up the stop sign when left fielder Hideki Matsui quickly threw the ball to third baseman Aaron Boone. Swann, who was too far past third base, got caught in a rundown and was tagged out. When the inning ended with the Orioles failing to score a run, the match was suspended and replayed in its entirety eight days later on September 26 as part of a twi-night doubleheader at Yankee Stadium. The Orioles would have had a 21 victory had Swann successfully crossed home plate because the game became official upon the completion of the fifth inning.

question:
Question: Who was Akbar's predecessor to the Mughal throne? Passage:Gauda was once the "capital of the ancient bhukti or political division of Bengal known as Pundravardhana which lay on the eastern extremity of the Gupta Empire." During the rule of the Sena Dynasty, in the 11th-12th century, Gauda was rebuilt and extended as Lakshmanawati (later Lakhnauti), and it became the hub of the Sena empire. Gauda was conquered by Muhammad bin Bakhtiyar Khalji in 1205. During the Turko-Afghan period, "the city of Lakhnauti or Gauda continued to function initially as their capital but was abandoned in 1342 by the Ilyas Shahi sultans in favour of Pandua because of major disturbances along the river course of the Ganga." "Pandua then lay on the banks of the Mahananda, which was the major waterway of the sultanate at the time. However, when the Mahananda too began to veer away from the site of Pandua in the mid-15th century, Gauda was rebuilt and restored to the status of capital city by the Hussain Shahi sultans"... With the ascent of Akbar to the Mughal throne at Delhi... the Mughals annexed the ancient region of Gauda in 1576 and created the Diwani of Bengal. The centre of regional power shifted across the Ganga to Rajmahal. Following the demise of the independent sultanate, the regional importance of the Gauda or Malda region declined irreversibly and the city of Gauda was eventually abandoned.

Question: Which of Glen's parents' heritages has more people? Passage:Marla grew up on the South Side of Chicago, the daughter of Dell Glen (American-Jamaican) and Cortez Glen (Mexican-American). Glen's father was a blues guitarist, her grandmother a gospel singer, and her mother was friends with the blues guitarist B.B. King. Her mother Dell graduated from the University of Chicago and went on to become a successful banker who worked for Merrill Lynch. Glen's father, an American patriot who joined the military at a young age, became an engineer based in Frankfurt, Germany. Like many other children in Chicago's historic Bronzeville neighborhood (also known as the Black Metropolis) who received gifts and inspiration from folks like Muddy Waters and BB King, Marla was given a toy harmonica as a child, and her musical talent became immediately apparent. She was only 11 years old when she wrote her first song, "Repertoire", a title that has won three gold records and one platinum, and appears on her 1996 release, Love and Respect.
