Question: How many franchise locations are there of the place where the Terri Gibbs Trio performed? Passage:Gibbs was born in Miami, Florida, but raised in the Augusta, Georgia, suburb of Grovetown. Although born with eyesight, she lost it as a newborn due to an incubator accident. Despite her blindness, she learned to play piano at age three. As a child, she sang in the church choir and at talent contests, and at age seventeen, she opened for Bill Anderson. Her parents wanted her to be treated no differently from sighted people and she was sent to public school, graduating from Butler High School in Augusta in 1972. She performed in and around the Augusta area and eventually, she met Chet Atkins, who advised her to move to Nashville, Tennessee, to pursue a country music career, which she did at age eighteen. After failing to find a record deal, she returned to Miami and joined a band called Sound Dimension. She continued to perform locally, later forming a band called the Terri Gibbs Trio, which performed at a Steak and Ale in Augusta, Georgia. Gibbs then sent a demo tape to record producer Ed Penney of MCA Records, signing to the label in 1980. Penney was a former Boston disc jockey and a long-time songwriter. He liked her voice on her demo, but felt she needed stronger material. He co-wrote "Somebody's Knockin'" for her and also produced the song.

Question: Does the college that Harrison graduated from in 1922 have more students than the one he graduated from in 1924? Passage:Originally from New Brunswick, Harrison graduated from Nova Scotia Agricultural College in 1922, and, in 1924, from the Ontario Agricultural College with a B.Sc. in agriculture. He earned an MSc in plant pathology from Macdonald Campus of McGill University a year later. A doctoral degree he started at the University of Toronto in 1929 was abandoned due to the Great Depression. He established a herbarium of mycological specimens where he was employed for many years at the Kentville Research Station (now the Atlantic Food and Horticulture Research Centre); most of his collections are now housed at the Canadian National Mycological Herbarium. His early research concerned the fungal infestation of plants, such as that of Colletotrichum lindemuthianum on beans (Phaseolus). Working with John Frederick DeWitt Hockey, they made many contributions to the control and prevention of diseases of horticultural crops. They were among the first to use the sticky slide spore trap to estimate the densities of fungal spores.

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.
