Task: Question Answering
Input (English): Passage: Middle-class Princeton student Tom Townsend, an admirer of Charles Fourier, attends a debutante dress ball one evening on a whim. After the ball, a mix-up leads to his meeting a small group of young Upper East Side socialites known as the Sally Fowler Rat Pack, after the girl whose apartment they use for after-hours parties. Believing that they accidentally stole a taxi from Tom, they decide to invite him to their after-hours party, to prevent ill feelings.
Tom decides to attend the party, and befriends several other attendees, including Nick Smith, a cynic who takes Tom under his wing; Audrey, a shy girl who enjoys Regency era literature and has a crush on Tom; and Charlie, an overly philosophical friend with an unrequited love for Audrey. Tom learns that he and the Rat Pack have some common friends, including his ex-girlfriend Serena Slocumb, with whom he remains infatuated.
Under Nick's tutelage, Tom ingratiates himself to the Rat Pack and soon becomes a full-fledged member. Much of the film is composed of dialogues in which Tom and the Rat Pack discuss the nebulous social scene they occupy, including how they are coming of age just as the culture in which they were raised is ending, leaving them with uncertain social futures. During these discussions, Tom reveals that he, too, was raised wealthy, but that his father abandoned the family to marry another woman, leaving Tom and his mother with limited financial resources. As a result, Tom harbors a love-hate relationship with wealth and the upper class. 
Question: What is the full name of the group that Tom becomes a member of?
Output (English): Sally Fowler Rat Pack.
