Task: Question Answering
Input (English): Passage: Richard "Dick" Purcell, a taxi driver, aspires to achieve his dream of becoming a singer. After a couple of theatre critics discover him while riding in his cab, one of them recommends him to a radio producer. The producer's secretary, Alice Hughes, hears him sing and falls in love with him. She sets up an audition for Dick to sing for the sponsor, Mrs. Flaggenheim. He's late for his audition and blows his big chance. 
Convinced she must go to Italy to find a good enough singer, with enough "romance" to represent her fine cheese products, Mrs. Flaggenheim takes Alice with her to find one in Venice. Dick watches as Alice boards the ship and manages to get on board and work for his passage to Italy. When in Venice, he looks up his friend and mentor from New York City, professor de Vinci, who had gone ahead to use his old connections to help Dick's singing career. They manage to score a couple of jobs as gondoliers for an upcoming event.
Dick uses the opportunity to showcase his voice. Mrs. Flaggenheim hears him and wants to sign him to a contract immediately, thinking he's an authentic Italian named "Ricardo Purcelli". Alice recognizes him, but they continue to hide his true identity and they all go back to New York, where he quickly becomes a radio sensation. Alice's jilted boyfriend finds out Ricardo Purcelli is actually just Dick and gives him an ultimatum. Dick must decide if he wants to continue masquerading as Ricardo and finally attain the fame and fortune he'd always dreamed of....or give it all up for Alice, the one he loves. 
Question: In order to be with the radio producer's secretary, who must he stop pretending to be?
Output (English): Ricardo Purcelli.
