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?
answer:
Ricardo Purcelli.

Passage: Four lifelong friends from the Boston neighborhood of Charlestown, Douglas "Doug" MacRay, James "Jem" Coughlin, Albert "Gloansy" MacGloan, and Desmond "Dez" Elden, rob a bank. They take the manager, Claire Keesey, hostage, but release her unharmed. When they find out Claire lives in their neighborhood, Doug begins to follow her to find out how much she has told the police, and to make sure that Jem does not eliminate her as a witness. Soon a romance grows between them, which Doug hides from the gang. As they grow closer, Doug tells Claire of his search for his long-lost mother, who he believes went to live with his aunt in Tangerine, Florida. He also recounts his chance to be a professional hockey player which he threw away for a life of crime, following in his father's footsteps. She in turn tells Doug that she saw a tattoo on one of the robbers, and he realizes that she can identify Jem and send them all to prison. He knows that Jem will kill her if he discovers the truth, so he persuades her that the authorities cannot protect her, and she decides not to tell the police.
After Claire tells Doug about being harassed and her car vandalized by Alex, a local Dominican thug, Doug enlists Jem for a favor, which they can never talk about. Doug and Jem don hockey masks and violently assault the offenders without Jem knowing the true reason for the favor is to protect Claire. 
Question: What are the aliases of the people who take a hostage?
answer:
Doug.


question:
Passage: Sonora Webster lives with her sister and abusive aunt during the Great Depression.  She learns that because of her accidentally letting the cows loose and her suspension from school, her treasured horse Lightning has been sold and she will be placed in an orphanage.  Instead, Sonora slips out of the house during the night. She ends up at a county fair and sees a performance by Marie, a diving girl who rides a horse off a platform, and aspires to do the same. Doc Carver, Marie's employer, tells her she is too young but gives Sonora a job as a stable hand due to her ability with horses, and she begins traveling with them. Doc's son Al wins a wild horse in a card game and Sonora names him Lightning. She later surprises Doc by taming and riding Lightning, so he promises to train her as a diving girl if she can mount it while it's moving, which she succeeds after multiple attempts.  
Marie falls and dislocates her shoulder, leaving her unable to perform, and Sonora steps in. Although she has never dived with Lightning, their first jump is successful.  Marie becomes jealous, and as Doc tires of her diva-like behavior, she quits rather than share billing with Sonora. Al develops a romance with Sonora that strains his relationship with his father, leaving after a particularly bad fight.  Al promises to write to Sonora, but Doc hides his letters.  As Doc and the new stable hand Clifford leave the farm in search of work, Lightning falls ill with colic. Al returns, and he and Sonora work together to heal Lightning. Doc fails to find any jobs, but Al announces he has arranged a six-month contract to perform at the Steel Pier in Atlantic City, New Jersey, reconciling father and son. Doc passes away en route from a heart attack, and Al assumes his father's role as show presenter.  Sonora searches for Doc's jacket to give Al confidence on his first show, and finds one of Al's letters inside, confessing his love for her, letting him know she feels the same. 
Question: Who is able to mount Lightning while it is moving?
answer:

Sonora.
