Given a question and a context passage, generate the answer having the word or phrase from the context passage. Here, the answer should be a shortest continous span from the passage.

Example Input: Context: Chronic myeloid leukemia (CML) is characterized by the presence of the Philadelphia chromosome, which is associated with a balanced translocation involving chromosomes 9 and 22 to produce a fusion gene (bcr-abl) that gives rise to a constitutively activated Abl tyrosine kinase. This kinase led to the discovery of several small-molecule inhibitors, imatinib being the first and most successful of these. Resistance to imatinib results in some patients from Abl kinase point mutations. Overcoming imatinib resistance represents one of the biggest challenges facing clinicians in the modern management of CML. In this review, we discuss the current understanding of CML pathophysiology and mechanisms of imatinib resistance and how advancing this knowledge has led to the design of novel therapies in the area of blastic phase CML and Philadelphia chromosome-positive acute lymphoblastic leukemia with previous imatinib failure. 
 Question: What tyrosine kinase, involved in a Philadelphia- chromosome positive chronic myelogenous leukemia, is the target of Imatinib (Gleevec)?
Example Output: bcr-abl

Example Input: Context: In a New York City residence, Pierre Delacroix (Damon Wayans) rises to begin his daily routine. Brushing his teeth, he gives us by voice over a definition of satire. He tells us that with the rise of the Internet, video and interactive games, his field as a television writer has seen a drop in popularity. Meanwhile, in a dilapidated building, squatter Womack (Tommy Davidson) wakes up his friend Manray (Savion Glover) for a day of work. This consists of travelling to the CNS (Continental Network System) building where Delacroix works, and Manray tap dancing to entertain the workers. They then collect money from the workers. The men see Delacroix walk by, and ask him for monetary help in the form of work of some kind.Delacroix walks into a staff meeting late and is immediately castigated by his boss, Thomas Dunwitty (Michael Rapaport). Dunwitty informs the staff that CNS has poor ratings. He says he wants them to write funnier material, and ends the meeting. In the privacy of his office, Dunwitty tells Delacroix that the material Delacroix's been writing for him seems like it's about white people with black faces. Dunwitty asserts that Delacroix is an "oreo" with his Harvard education, because he won't write a "n----r show."The next day, Delacroix and his assistant Sloan Hopkins (Jada Pinkett Smith) talk. They've decided that Manray is the solution to his problem. Delacroix plans to write a show that will be so "offensive and racist," it will prove his point that the network only wants to see black buffoons on the air. Delacroix simply hopes to be fired, so he can be let go of his contract with CNS. Manray and Womack ask at the receptionist's desk for a "Delapoint" and the men working there tell them to step outside. However, Sloan steps into the lobby, sees what's happening, and escorts Manray and Womack to Delacroix's office. Delacroix explains to them that he has an idea for a television pilot, and they can make money with it. His main request is that Manray changes his name to Mantan, in an apparent homage to black character actor Mantan Moreland.On Sloan's walk home, she runs into her big brother Big Blak Afrika F/K/A Julius (Yasiin Bey). In Sloan's apartment, Julius and Sloan argue about his values, and he tells her to introduce him and his political hip-hop crew, the Mau Maus, to Delacroix.Delacroix has another meeting with Dunwitty. Delacroix proposes that the network start a variety show called "Mantan: The New Millenium Minstrel Show." Delacroix says that new faces are needed for the show, and has Sloan bring in Manray and Womack. The two men, respectively renamed "Mantan" and "Sleep'n Eat," will exhibit a range of stereotypical traits, Delacroix explains. Sloan is opposed to the proceedings, and suggests that there will be protest of the show they are planning. To seal the package, Manray dances atop a table in front of Dunwitty -- who immediately leaves to try to sell the show's concept to his executive bosses.Delacroix, Sloan and another woman hold auditions for the show. The first group of people (The Roots) audition to be the show's house band, The Alabama Porch Monkeys. After they perform, a dancer, a vulgar man shouting "I be smackin' my hoes," and a didgeridoo player all audition. The next hopeful is Honeycutt (Thomas Jefferson Byrd), an actor who bungles Shakespearean quotes and proclaims "N----s is a beautiful thing." Sloan's brother's group, the Mau Maus then do a fiery, confrontational performance; Pierre states via voice over that there is no place for them in his plan.Delacroix looks over a revised script for the show and confronts Dunwitty and his co-writer, Jukka about their alterations to it that even he finds racially offensive. Delacroix says that he won't be responsible for their changes, which Dunwitty says are to make the show funnier. Dunwitty says he knows black people better than Delacroix does, telling him, "Look

Example Input: Context: Anna Foster (Mandy Moore) is the daughter of the President of the United States, James (Mark Harmon) and First Lady Michelle Foster (Caroline Goodall).When a hassle of Secret Service agents ruins a first date, Anna demands some freedom. Her dad agrees to send only two agents with Anna and Gabrielle La Clare (Beatrice Rosen) to a concert when Anna goes to Prague with her parents. A sexy new look for Anna causes her father to renege. When Anna discovers the concert is filled with agents and that her father has broken his promise, Gabrielle helps Anna elude her protectors. Outside the concert, Anna meets Ben Calder (Matthew Goode), and asks him to drive her to escape the agents. Anna goes to a bar with Ben and proceeds to get drunk. Unbeknownst to Anna, Ben is with the Secret Service, and tells agents Alan Weiss (Jeremy Piven) and Cynthia Morales (Annabella Sciorra) where Anna is. The President orders the three agents to have Ben guard Anna without telling her who he really is, to give her an illusion of freedom with a guarantee of safety. Believing herself free of her guards for the first time in years, Anna jumps into the Vltava River naked, mistaking it for the Danube, and Ben has to fish her out (he stays clothed). Weiss and Morales buy the camera from someone taking pictures of the skinny-dipping Anna. Anna and Ben climb a rooftop to watch an opera being shown in a plaza, where Anna eventually falls asleep with Ben guarding her, and Weiss and Morales watching from another roof.The next morning, Anna calls her parents to avoid getting into further trouble with them. Knowing she is safe, her father is initially indulgent, and Anna is about to return, but his tone changes when he is shown the photos of her nude in the river. The First Lady, however, asks, "What happened to 'let freedom ring?'" (That had been his earlier line when he had decided to let her stay out with Ben.) Anna is outraged at both her dad's sudden imperious tone and finding out that he traced her call. She decides to meet Gabrielle at the Love Parade in Berlin and return to her parents right before the plane trip home. Ben goes with her on the train, where they meet Scotty McGruff (Martin Hancock), a flighty romantic obsessed with Six Million Dollar Man stickers and the interconnectivity of the world, he gives them a stack of stickers and tells them to stick them up in random places, then one day when they are unhappy, they will see one and it will make them smile. Through him, the two learn that they have boarded a Venice-bound train. When they arrive in Venice, Ben calls the other agents to tell them where they are but has to leave the phone dangling when he realizes he can no longer see Anna. He finds her and McGruff getting new clothes, and the three explore Venice - until McGruff steals their wallets. Ben is about to tell the cafe they cannot pay when Anna is recognized and races off to avoid being identified as the First Daughter. Ben follows, and they tell a story of marrying, against the wishes of Anna's parents, to get a gondola ride from a kind-hearted gondolier, Eugenio (Joseph Long). Ben kisses Anna during the ride to hide her from the cafe staff's sight. Since they have no place to stay, Eugenio invites them to his and his mother Maria's (Miriam Margolyes) house. That night, thinking the kiss meant that Ben cares for her, Anna offers herself to him. To dissuade her, Ben is disingenuous and harsh. Anna finally gets in the bed alone, while Ben lies on the floor.The next day, Eugenio drives them to the Austrian border, as Weiss and Morales show up at Maria's looking for the gondolier with whom Anna and Ben were last seen. Maria tells them that Anna and Ben are married, which is reported to Anna's parents. Upset that Ben rejected her, Anna gets a ride on a truck, leaving Ben to
