Problem: Background: Hattie McDaniel (June 10, 1895 - October 26, 1952) was an American stage actress, professional singer-songwriter, and comedian. She is best known for her role as "Mammy" in Gone with the Wind (1939), for which she won the Academy Award for Best Supporting Actress, the first Academy Award won by an African American entertainer. In addition to acting in many films, McDaniel was a radio performer and television star; she was the first black woman to sing on radio in the United States. She appeared in over 300 films, although she received screen credits for only 80 or so.
Context: The whereabouts of McDaniel's Oscar are currently unknown. In 1992, Jet magazine reported that Howard University could not find it and alleged that it had disappeared during protests in the 1960s. In 1998, Howard University stated that it could find no written record of the Oscar having arrived at Howard. In 2007, an article in the Huffington Post repeated rumors that the Oscar had been cast into the Potomac River by angry civil rights protesters in the 1960s. The assertion reappeared in the Huffington Post under the same byline in 2009.  In 2010, Mo'Nique, the winner of the Academy Award for Best Supporting Actress, wearing a blue dress and gardenias in her hair, as McDaniel had at the ceremony in 1940, in her acceptance speech thanked McDaniel "for enduring all that she had to so that I would not have to". Her speech revived interest in the whereabouts of McDaniel's plaque. In 2011, J. Freedom duLac reported in the Washington Post that the plaque had disappeared in the 1960s.  In November 2011, W. B. Carter, of the George Washington University Law School, published the results of her year-and-a-half-long investigation into the Oscar's fate. Carter rejected claims that students had stolen the Oscar (and thrown it in the Potomac River) as wild speculation or fabrication that traded on long-perpetuated stereotypes of blacks. She questioned the sourcing of the Huffington Post stories. Instead, she argued that the Oscar was likely returned to Howard University's Channing Pollack Theater Collection between the spring of 1971 and the summer of 1973 or had possibly been boxed and stored in the drama department at that time. The reason for its removal, she argued, was not civil rights unrest but rather efforts to make room for a new generation of black performers. If neither the Oscar nor any paper trail of its ultimate destiny can be found at Howard today, she suggested, inadequate storage or record-keeping in a time of financial constraints and national turbulence may be blamed. She also suggested that a new generation of caretakers may have failed to realize the historic significance of the 5 1/2" x 6" plaque.
Question: What did she win the Oscar for?
Answer: 

Problem: Background: George Michael Cohan (July 3, 1878 - November 5, 1942), known professionally as George M. Cohan, was an American entertainer, playwright, composer, lyricist, actor, singer, dancer and producer. Cohan began his career as a child, performing with his parents and sister in a vaudeville act known as "The Four Cohans." Beginning with Little Johnny Jones in 1904, he wrote, composed, produced, and appeared in more than three dozen Broadway musicals. Cohan published more than 300 songs during his lifetime, including the standards "Over There", "Give My Regards to Broadway", "The Yankee Doodle Boy" and "You're a Grand Old Flag".
Context: Cohan began writing original skits (over 150 of them) and songs for the family act in both vaudeville and minstrel shows while in his teens. Soon he was writing professionally, selling his first songs to a national publisher in 1893. In 1901 he wrote, directed and produced his first Broadway musical, The Governor's Son, for The Four Cohans. His first big Broadway hit in 1904 was the show Little Johnny Jones, which introduced his tunes "Give My Regards to Broadway" and "The Yankee Doodle Boy."  Cohan became one of the leading Tin Pan Alley songwriters, publishing upwards of 300 original songs noted for their catchy melodies and clever lyrics. His major hit songs included "You're a Grand Old Flag," "Forty-Five Minutes from Broadway," "Mary Is a Grand Old Name," "The Warmest Baby in the Bunch," "Life's a Funny Proposition After All," "I Want To Hear a Yankee Doodle Tune," "You Won't Do Any Business If You Haven't Got a Band," "The Small Town Gal," "I'm Mighty Glad I'm Living, That's All," "That Haunting Melody," "Always Leave Them Laughing When You Say Goodbye", and America's most popular World War I song "Over There", which was recorded by Enrico Caruso among others. The latter song reached such currency among troops and shipyard workers that a ship was named "Costigan" after Cohan's grandfather, Dennis Costigan. During the christening, "Over There" was played.  From 1904 to 1920, Cohan created and produced over 50 musicals, plays and revues on Broadway together with his friend Sam H. Harris, including Give My Regards to Broadway and the successful Going Up in 1917, which became a smash hit in London the following year. His shows ran simultaneously in as many as five theatres. One of Cohan's most innovative plays was a dramatization of the mystery Seven Keys to Baldpate in 1913, which baffled some audiences and critics but became a hit. Cohan further adapted it as a film in 1917, and it was adapted for film six more times, as well as for TV and radio. He dropped out of acting for some years after his 1919 dispute with Actors' Equity Association.  In 1925, he published his autobiography, Twenty Years on Broadway and the Years It Took To Get There.
