full_context: Document 1: 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 2: 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 3: San Diego: In 2000, the median income for a household in the city was $45,733, and the median income for a family was $53,060. Males had a median income of $36,984 versus $31,076 for females. The per capita income for the city was $23,609. According to Forbes in 2005, San Diego was the fifth wealthiest U.S. city but about 10.6% of families and 14.6% of the population were below the poverty line, including 20.0% of those under age 18 and 7.6% of those age 65 or over. Nonetheless, San Diego was rated the fifth-best place to live in the United States in 2006 by Money magazine.
Document 4: 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 5: Harvard University: Harvard's 2,400 professors, lecturers, and instructors instruct 7,200 undergraduates and 14,000 graduate students. The school color is crimson, which is also the name of the Harvard sports teams and the daily newspaper, The Harvard Crimson. The color was unofficially adopted (in preference to magenta) by an 1875 vote of the student body, although the association with some form of red can be traced back to 1858, when Charles William Eliot, a young graduate student who would later become Harvard's 21st and longest-serving president (1869–1909), bought red bandanas for his crew so they could more easily be distinguished by spectators at a regatta.
Document 6: MIT Blackjack Team: The MIT Blackjack Team was a group of students and ex-students from Massachusetts Institute of Technology, Harvard Business School, Harvard University, and other leading colleges who used card counting techniques and more sophisticated strategies to beat casinos at blackjack worldwide. The team and its successors operated successfully from 1979 through the beginning of the 21st century. Many other blackjack teams have been formed around the world with the goal of beating the casinos.
Document 7: Ann Arbor, Michigan: High tech companies have located in the area since the 1930s, when International Radio Corporation introduced the first mass-produced AC/DC radio (the Kadette, in 1931) as well as the first pocket radio (the Kadette Jr., in 1933). The Argus camera company, originally a subsidiary of International Radio, manufactured cameras in Ann Arbor from 1936 to the 1960s. Current firms include Arbor Networks (provider of Internet traffic engineering and security systems), Arbortext (provider of XML-based publishing software), JSTOR (the digital scholarly journal archive), MediaSpan (provider of software and online services for the media industries), Truven Health Analytics, and ProQuest, which includes UMI. Ann Arbor Terminals manufactured a video-display terminal called the Ann Arbor Ambassador during the 1980s. Barracuda Networks, which provides networking, security, and storage products based on network appliances and cloud services, opened an engineering office in Ann Arbor in 2008 on Depot St. and recently announced it will move downtown to occupy the building previously used as the Borders headquarters.

Full-time year-round male workers had a median income of $52,544 versus $46,540 for full-time year-round female workers.

Document 10: Venture capital: Before World War II (1939 -- 1945), money orders (originally known as ``development capital '') remained primarily the domain of wealthy individuals and families. Only after 1945 did`` true'' private equity investments begin to emerge, notably with the founding of the first two venture capital firms in 1946: American Research and Development Corporation (ARDC) and J.H. Whitney & Company.
Document 11: Harvard University: Established originally by the Massachusetts legislature and soon thereafter named for John Harvard (its first benefactor), Harvard is the United States' oldest institution of higher learning, and the Harvard Corporation (formally, the President and Fellows of Harvard College) is its first chartered corporation. Although never formally affiliated with any denomination, the early College primarily trained Congregationalist and Unitarian clergy. Its curriculum and student body were gradually secularized during the 18th century, and by the 19th century Harvard had emerged as the central cultural establishment among Boston elites. Following the American Civil War, President Charles W. Eliot's long tenure (1869–1909) transformed the college and affiliated professional schools into a modern research university; Harvard was a founding member of the Association of American Universities in 1900. James Bryant Conant led the university through the Great Depression and World War II and began to reform the curriculum and liberalize admissions after the war. The undergraduate college became coeducational after its 1977 merger with Radcliffe College.
Document 12: Blackjack: Once all the players have completed their hands, it is the dealer's turn. The dealer hand will not be completed if all players have either busted or received Blackjacks. The dealer then reveals the hidden card and must hit until the cards total 17 or more points. (At most tables the dealer also hits on a ``soft ''17, i.e. a hand containing an ace and one or more other cards totaling six.) Players win by not busting and having a total higher than the dealer, or not busting and having the dealer bust, or getting a blackjack without the dealer getting a blackjack. If the player and dealer have the same total (not counting blackjacks), this is called a`` push'', and the player typically does not win or lose money on that hand. Otherwise, the dealer wins.
Document 13: Boston: In the city, the population was spread out with 21.9% at age 19 and under, 14.3% from 20 to 24, 33.2% from 25 to 44, 20.4% from 45 to 64, and 10.1% who were 65 years of age or older.

There were 252,699 households, of which 20.4% had children under the age of 18 living in them, 25.5% were married couples living together, 16.3% had a female householder with no husband present, and 54.0% were non-families. 37.1% of all households were made up of individuals and 9.0% had someone living alone who was 65 years of age or older. The average household size was 2.26 and the average family size was 3.08.
Document 14: Boston: Several universities located outside Boston have a major presence in the city. Harvard University, the nation's oldest institute of higher education, is centered across the Charles River in Cambridge but has the majority of its land holdings and a substantial amount of its educational activities in Boston. Its business, medical, dental, and public health schools are located in Boston's Allston and Longwood neighborhoods. Harvard has plans for additional expansion into Allston. The Massachusetts Institute of Technology (MIT), which originated in Boston and was long known as "Boston Tech", moved across the river to Cambridge in 1916. Tufts University, whose main campus is north of the city in Somerville and Medford, locates its medical and dental school in Boston's Chinatown at Tufts Medical Center, a 451-bed academic medical institution that is home to both a full-service hospital for adults and the Floating Hospital for Children.
Document 15: American Research and Development Corporation: American Research and Development Corporation (ARDC) was a venture capital and private equity firm founded in 1946 by Georges Doriot, the former dean of Harvard Business School and "father of venture capitalism", with Ralph Flanders and Karl Compton (former president of MIT).
