Question: On what day did Alexander Graham Bell return to the city, that is the capital of the state where Wellesley College is in Mona Lisa Smile?

full_context: Document 1: Carol Strickland: Strickland graduated from Rhodes College in Memphis (Tennessee) in 1968. She studied English literature and earned a PhD from the University of Michigan in 1973. She taught at various universities during the 1980, such as Rutgers University and the State University of New York in Stony Brook. During a sabbatical in Geneva, Switzerland, she began writing widely on contemporary art. Having returned to the United States, she regularly published articles in The Christian Science Monitor, The New York Times, and the Wall Street Journal, but also for magazines, such as The Nation and Art & Antiques. Her articles are mainly focused on art and architecture. She is also the author of "The Annotated Mona Lisa" and "The Annotated Arch". "The Annotated Mona Lisa" includes articles on art history and architectural history from antiquity to the post-modern period. It has been translated in various languages.
Document 2: Alexander Graham Bell: In 1875, Bell developed an acoustic telegraph and drew up a patent application for it. Since he had agreed to share U.S. profits with his investors Gardiner Hubbard and Thomas Sanders, Bell requested that an associate in Ontario, George Brown, attempt to patent it in Britain, instructing his lawyers to apply for a patent in the U.S. only after they received word from Britain (Britain would issue patents only for discoveries not previously patented elsewhere).
Document 3: Mona Lisa Smile: Mona Lisa Smile is a 2003 American drama film produced by Revolution Studios and Columbia Pictures in association with Red Om Films Productions, directed by Mike Newell, written by Lawrence Konner and Mark Rosenthal, and starring Julia Roberts, Kirsten Dunst, Julia Stiles and Maggie Gyllenhaal. The title is a reference to the "Mona Lisa", the famous painting by Leonardo da Vinci, and to the song of the same name, originally performed by Nat King Cole, which was covered by Seal for the movie. Julia Roberts received a record $25 million for her performance, the highest ever earned by an actress at that time.
Document 4: Alexander Graham Bell: Bell's patent 174,465, was issued to Bell on March 7, 1876, by the U.S. Patent Office. Bell's patent covered "the method of, and apparatus for, transmitting vocal or other sounds telegraphically ... by causing electrical undulations, similar in form to the vibrations of the air accompanying the said vocal or other sound" [N 16] Bell returned to Boston the same day and the next day resumed work, drawing in his notebook a diagram similar to that in Gray's patent caveat.
Document 5: Boston: With nearly a third of Bostonians using public transit for their commute to work, Boston has the fifth-highest rate of public transit usage in the country. Boston's subway system, the Massachusetts Bay Transportation Authority (MBTA—known as the "T") operates the oldest underground rapid transit system in the Americas, and is the fourth-busiest rapid transit system in the country, with 65.5 miles (105 km) of track on four lines. The MBTA also operates busy bus and commuter rail networks, and water shuttles.
Document 6: Erika Giovanna Klien: Erika Giovanna Klien began her studies at the Vienna School of Applied Arts, also known as "Kunstgewerbeschule Wien" in Vienna, Austria in 1919 and graduated in 1925. She was a student of Dr. Franz Cizek and became one of his teaching assistants at his Juvenile Art Class. In Cizek's course, Theory of Ornamental Form, Klien was introduced to a new style known as Viennese Kinetism. Kinetism emphasized movement and modern vitality, in a way similar to French Cubism, Italian Futurism and Russian Constructivism. She developed the technique and theories of Kinetism throughout her artistic life and became its leading exponent.
Document 7: Alexander Graham Bell: The question of priority for the variable resistance feature of the telephone was raised by the examiner before he approved Bell's patent application. He told Bell that his claim for the variable resistance feature was also described in Gray's caveat. Bell pointed to a variable resistance device in Bell's previous application in which Bell described a cup of mercury, not water. Bell had filed the mercury application at the patent office a year earlier on February 25, 1875, long before Elisha Gray described the water device. In addition, Gray abandoned his caveat, and because he did not contest Bell's priority, the examiner approved Bell's patent on March 3, 1876. Gray had reinvented the variable resistance telephone, but Bell was the first to write down the idea and the first to test it in a telephone.
Document 8: Boston: Boston is sometimes called a "city of neighborhoods" because of the profusion of diverse subsections; the city government's Office of Neighborhood Services has officially designated 23 neighborhoods.
Document 9: Boston: Federally, Boston is split between two congressional districts. The northern three-fourths of the city is in the 7th district, represented by Mike Capuano since 1998. The southern fourth is in the 8th district, represented by Stephen Lynch. Both are Democrats; a Republican has not represented a significant portion of Boston in over a century. The state's senior member of the United States Senate is Democrat Elizabeth Warren, first elected in 2012. The state's junior member of the United States Senate is Democrat Ed Markey, who was elected in 2013 to succeed John Kerry after Kerry's appointment and confirmation as the United States Secretary of State.
Document 10: Katherine Weare: She was educated at the Grey Coat Hospital, Westminster, the University of Kent at Canterbury, Goldsmiths College, University of London and the Institute of Education, University of London. She began her career as a teacher of English and Drama in secondary schools, and moved into higher education at the age of 25. She has researched and written extensively on mental health, emotional wellbeing, emotional and social learning.
Document 11: Alexander Graham Bell: Although Alexander Graham Bell is most often associated with the invention of the telephone, his interests were extremely varied. According to one of his biographers, Charlotte Gray, Bell's work ranged "unfettered across the scientific landscape" and he often went to bed voraciously reading the Encyclopædia Britannica, scouring it for new areas of interest. The range of Bell's inventive genius is represented only in part by the 18 patents granted in his name alone and the 12 he shared with his collaborators. These included 14 for the telephone and telegraph, four for the photophone, one for the phonograph, five for aerial vehicles, four for "hydroairplanes" and two for selenium cells. Bell's inventions spanned a wide range of interests and included a metal jacket to assist in breathing, the audiometer to detect minor hearing problems, a device to locate icebergs, investigations on how to separate salt from seawater, and work on finding alternative fuels.
Document 12: Boston: In addition to city government, numerous commissions and state authorities—including the Massachusetts Department of Conservation and Recreation, the Boston Public Health Commission, the Massachusetts Water Resources Authority (MWRA), and the Massachusetts Port Authority (Massport)—play a role in the life of Bostonians. As the capital of Massachusetts, Boston plays a major role in state politics.
Document 13: Alexander Graham Bell: On March 10, 1876, three days after his patent was issued, Bell succeeded in getting his telephone to work, using a liquid transmitter similar to Gray's design. Vibration of the diaphragm caused a needle to vibrate in the water, varying the electrical resistance in the circuit. When Bell spoke the famous sentence "Mr. Watson—Come here—I want to see you" into the liquid transmitter, Watson, listening at the receiving end in an adjoining room, heard the words clearly.
Document 14: Boston: Tourism also composes a large part of Boston's economy, with 21.2 million domestic and international visitors spending $8.3 billion in 2011; excluding visitors from Canada and Mexico, over 1.4 million international tourists visited Boston in 2014, with those from China and the United Kingdom leading the list. Boston's status as a state capital as well as the regional home of federal agencies has rendered law and government to be another major component of the city's economy. The city is a major seaport along the United States' East Coast and the oldest continuously operated industrial and fishing port in the Western Hemisphere.
Document 15: Mona Lisa Smile: In 1953, Katherine Ann Watson (Julia Roberts), a 30 - year - old graduate student in the department of Art History at UCLA, takes a position teaching ``History of Art ''at Wellesley College, a conservative women's private liberal arts college in Massachusetts. At her first class, Katherine discovers that her students have already memorized the entire textbook and syllabus, so she uses the classes to introduce them to Modern Art and encourages discussion about topics such as what makes good art. Katherine comes to know her students and seeks to inspire them to achieve more than marriage to eligible young men.
