Question: What unit number in the Cleveland Court Apartments belonged to the woman who was referred to as "the first lady of civil rights?"
Context: The National Emergency Committee Against Mob Violence (NECAMV) was an umbrella organization of civil rights advocates, religious leaders, and labor activists created in 1946 in response to a spate of racially motivated attacks against African-Americans in the summer of that year.  NECAMV included representatives from the NAACP, the Urban League, the Federal Council of Churches, and the American Federation of Labor, among others.  Prominent individuals such as former First Lady Eleanor Roosevelt also were members.  The group was formed in order to lobby President Harry S Truman to take steps to more fully enforce the rights of African-Americans.  The NECAMV met with Truman on September 19, 1946 and, after relating to him in graphic detail the circumstances of the attacks, Truman insisted that something needed to be done to address the problem.  He pledged to issue an executive order establishing a blue ribbon panel that would be charged with investigating the situation and proposing ways of reducing racial tensions and providing for more rigorous enforcement of civil rights. Septima Poinsette Clark (May 3, 1898 – December 15, 1987) was an American educator and civil rights activist.  Clark developed the literacy and citizenship workshops that played an important role in the drive for voting rights and civil rights for African Americans in the Civil Rights Movement.  Septima Clark's work was commonly under appreciated by Southern male activists.  She became known as the "Queen mother" or "Grandmother" of the Civil Rights Movement in the United States.  Martin Luther King, Jr. commonly referred to Clark as "The Mother of the Movement".  Clark's argument for her position in the Civil Rights Movement was one that claimed "knowledge could empower marginalized groups in ways that formal legal equality couldn't." The West Franklin Street Historic District is a national historic district located at Richmond, Virginia.  It is located along the northern boundary of the Fan district.  The district encompasses 71 contributing buildings built between about 1870 and the 1920.  It was originally developed as a primarily residential district with buildings in a variety of popular late-19th and early-20th century architectural styles including Greek Revival, Romanesque, Georgian Revival, Queen Anne, and Italianate.  Many of the dwellings have been converted to commercial use.  In addition, the district’s private houses have been converted into multi-family housing and departmental offices for Virginia Commonwealth University.  Notable buildings include Franklin Terrace, the Ritter-Hickock House, First Independent Church, Founder's Hall, the Raleigh Building, The Greyston Apartments, Gresham Court Apartments, and the Beth Ahabah Congregation Hall and Synagogue. Rosa Louise McCauley Parks (February 4, 1913 – October 24, 2005) was an activist in the Civil Rights Movement, whom the United States Congress called "the first lady of civil rights" and "the mother of the freedom movement". The Cleveland Court Apartments 620–638 is a historic apartment building in the Cleveland Court Apartment Complex in Montgomery, Alabama.  It is significant to the history of the modern Civil Rights Movement in the United States.  Unit 634 was home to civil rights activist Rosa Parks, her husband Raymond, and her mother, Leona McCauley, during the Montgomery Bus Boycott from 1955 to 1956.  The building was placed on the Alabama Register of Landmarks and Heritage on March 30, 1989 and the National Register of Historic Places on October 29, 2001. The Civil Rights Cases, 109 US 3 (1883) were a group of five US Supreme Court constitutional law cases.  Against the famous dissent of Justice Harlan, a majority held the Civil Rights Act of 1875 was unconstitutional, because Congress lacked authority to regulate private affairs under the Fourteenth Amendment, and that the Thirteenth Amendment "merely abolishes slavery".  The Civil Rights Act of 1875 had banned race discrimination in access to services offered to the public.  The decision was effectively reversed in the jurisprudence of the Supreme Court from 1937, and finally by legislation under the Civil Rights Act of 1964. Play Street Soccer is a non-profit organization based in Carrboro, North Carolina.  The organization began as an on-site program of the Chapel Hill and Carrboro Human Rights Center under the leadership of coach John Mulholland in 2010.  Originally, Coach Mulholland taught soccer lessons to children living in the Abbey Court Apartments, historically an apartment complex for low-income families.  Since its beginning, Play Street Soccer has now grown to host pick-up soccer games at three low-income neighborhoods in Chapel Hill and Carrboro through the efforts of UNC student, Carey Averbook.  Games are held at Abbey Court Apartments, Rogers Road, and Estes Park apartments throughout the week during the fall and spring.  Volunteers from The University of North Carolina at Chapel Hill help facilitate the games as part of various service-learning classes offered at the institution. The Civil Rights Commission (Spanish: "Comisión de Derechos Civiles" ) is an official entity within the legislative branch of the government of Puerto Rico charged with investigating violations of citizens' civil rights.

Loren Miller (January 20, 1903 - July 14, 1967) was an American journalist, civil rights activist, attorney and judge.  Miller was appointed to the Superior Court of California, County of Los Angeles, by former governor Edmund G. Brown in 1964, serving until 1967.  Miller was a specialist in housing discrimination, whose involvement in the early stages of the Civil Rights Movement earned him a reputation as a tenacious fighter for equal housing opportunities for minorities.  Miller argued some of the most historic civil rights cases ever heard before the U.S. Supreme Court.  He was chief counsel before the court in the 1948 decision that led to the outlawing of racial restrictive covenants, Shelley v. Kraemer. The 6004th Air Intelligence Service Squadron was "the first covert (military intelligence) collection agency in the history of the United States Air Force".  Begun by Major Donald Nichols as an impromptu extension of his pre-Korean War espionage in 1950, it was first dubbed "Special Activities Unit Number One".  In April or May 1951, it officially became the 6004th Air Intelligence Service Squadron.  The 6004th was an unorthodox unit that engaged in espionage and aircrew escape and evasion, as well as collecting information.  It was Far East Air Force's primary supplier of intelligence for the war, generating as many as 900 reports per month.
