Input: Question: Is the opera house that Brambilla visited while in Russia still standing? Passage 1:Getty Square is Yonkers' downtown and the civic center and central business district of the city. Much of southwest Yonkers grew densely along the multiple railroads and trolley (now bus) lines along South Broadway and in Getty Square, connecting to New York City. Clusters of apartment buildings surrounded the stations of the Yonkers branch of the New York and Putnam Railroad and the Third Avenue Railway trolley lines and these buildings still remain although now served by the Bee-Line Bus System. The railroad companies themselves built neighborhoods of mixed housing types ranging from apartment buildings to large mansions in areas like Park Hill wherein the railroad also built a funicular to connect it with the train station in the valley. This traditionally African-American and white area has seen a tremendous influx of immigrants from Mexico, Central America, the Caribbean, South Asia, and the Middle East. Off South Broadway and Yonkers Avenue one can find residential neighborhoods, such as Lowerre, Nodine Hill, Park Hill, and Hudson Park (off the Hudson River) with a mix of building styles ranging from dense clusters of apartment buildings, blocks of retail with apartments above, multifamily row houses, and detached single-family homes.
 Passage 2:Mrs. Bacon spent her early childhood in New York City and moved to Florida as an adolescent. She went to Antioch College, where she met her husband, Allen Bacon. During World War II, she accompanied her husband to work at Springfield Hospital in Sykesville, Maryland as his assignment for conscientious objector status. She also worked at the American Friends Service Committee for many years and was the inspiration for the rehabilitation of the Fair Hill Burial Ground, a historic Quaker cemetery in North Philadelphia and the final resting place of abolitionists Lucretia Mott and Robert Purvis. Mrs. Bacon authored biographies of both Mott and Purvis. A longtime trustee and Vice President of the Pennsylvania Abolition Society, she wrote a feature article titled "The Pennsylvania Abolition Society's Mission for Black Education" for the Historical Society of Pennsylvania's November 2005 newsletter. She was a founding board member of Women's Way, the country’s oldest and largest funding federation for women’s organizations. Bacon died at her home at Crosslands in Kennett Square, Pennsylvania on February 24, 2011.
 Passage 3:After her professional debut in 1831, Brambilla initially sang in several smaller opera houses in northern Italy but in 1833 scored a considerable success at Milan's Teatro Carcano singing Agnese in Bellini's Beatrice di Tenda and the leading soprano role in Fioravanti's Le cantatrici villane. She then appeared on Russia at the Odessa Opera House, which at the time specialised in Italian opera. Upon her return to Milan in 1837, she sang with her sister Marietta at La Scala in the world premiere of In morte di Maria Malibran de Bériot, a cantata in memory of Maria Malibran composed by Gaetano Donizetti, Giovanni Pacini, Saverio Mercadante, Nicola Vaccai and Pietro Antonio Coppola. After singing in Barcelona, she returned to La Scala for the 1839/1840 season in Mercadante's Le due illustri rivali and the world premieres of Mazzucato's I corsari and Coccia's Giovanna II.
