. Passage 2: John Ford (18941973) was an American film director whose career spanned from 1913 to 1971. During this time he directed more than 140 films. Born in Maine, Ford entered the filmmaking industry shortly after graduating from high school with the help of his older brother, Francis Ford, who had established himself as a leading man and director for Universal Studios. After working as an actor, assistant director, stuntman, and prop man often for his brother Universal gave Ford the opportunity to direct in 1917. Initially working in short films, he quickly moved into features, largely with Harry Carey as his star. In 1920 Ford left Universal and began working for the Fox Film Corporation. During the next ten years he directed more than 30 films, including the westerns The Iron Horse (1924) and 3 Bad Men (1926), both starring George O'Brien, the war drama Four Sons and the Irish romantic drama Hangman's House (both 1928 and both starring Victor McLaglen). In the same year of these last two films, Ford directed his first all-talking film, the short Napoleon's Barber. The following year he directed his first all-talking feature, The Black Watch.
. Passage 3: Since the late 1970s, the central part of NYU is its Washington Square campus in the heart of Greenwich Village. Despite being public property, and expanding the Fifth Avenue axis into Washington Square Park, the Washington Square Arch is the unofficial symbol of NYU. Until 2008, NYU's commencement ceremony was held in Washington Square Park. However, due to space constraints, ceremonies are now held at the Yankee Stadium. Important facilities at Washington Square are the Elmer Holmes Bobst Library, designed by Philip Johnson and Richard Foster, who also designed several other structures, such as Tisch Hall, Meyer Hall, and the Hagop Kevorkian Center. When designing these buildings Johnson and Foster also set up a master plan for a complete redesign of the NYU Washington Square campus. However, it was never implemented. Other historic buildings include the Silver Center (formerly known as "Main building"); the Brown Building of Science; Judson Hall, which houses the King Juan Carlos I of Spain Center; Vanderbilt Hall, the historic townhouse row on Washington Square North; The Grey Art Gallery at 100 Washington Square East, housing the New York University art collection and featuring museum quality exhibitions; the Kaufman Management Center; and the Torch Club the NYU dining and club facility for alumni, faculty, and administrators. Just a block south of Washington Square is NYU's Washington Square Village, housing graduate students and junior and senior faculty residences in the Silver Towers, designed by I. M. Pei, where an enlargement of Picasso's sculpture Bust of Sylvette (1934) is displayed.

Q: Question: What artist wrote the song that Vallee begins to sing after Betty wishes her good night? Passage 1:The film begins at Betty Boop's house, as she throws a house party. She is seen in a room serving a drink to the other animals. Due to the drink, an argument breaks out between two animals, whom ultimately agree at the end to toss a coin. However, when one of the animals flips a coin, it comically ends up sideways. So one of the animals flips again, but flips it so high that a bird comically catches it and takes it. After that, Betty then asks for anyone that can sing and dance. A rabbit then comes forward and says that he can play the piano. So, Betty asks Hanson to bring in the piano. However Hanson is a small bug, so comically has to tug at it to get it in the room, whilst a big hippo comically only carries a stool. Betty then hands the rabbit some sheet music, but the rabbit says that he only plays "by ear". However, when he starts to play, he comically uses his ears to play the piano. Betty then requests for a singer whilst she plays. All of the animals decline her request. Until a picture of Rudy Vallee from a book of sheet music comes to life and says he will sing. Betty then asks Vallee is the songs will be old or new, Vallee then says that he'll sing songs that they will all know; and he'll sing them with the bouncing ball. His first song that he sings is "Deep Night", with footage of beaches and rainforests accompanying the song . The second song that he sings is "A Little Kiss Every Morning", with footage of a painting firstly showcasing multiple species of birds kissing, then transitioning to babies and their mothers, then to young couples, and then to elderly couples. The final song that Vallee sings is "Stein Song", a college song, with accompanying footage showcasing a noisy game of American football. After the three songs, the party concludes, and all the guests depart from Betty's house. Betty then wishes Vallee good night. Vallee, who is in a picture frame, begins to sing "Good Night Sweetheart". After that performance, Betty then laughs and wishes him a good night. The film ends with Vallee singing "Keep a Little Song Handy".
