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: Highly conserved sequences at the 5' splice site and branch site of U12-dependent introns are important determinants for splicing by U12-dependent spliceosomes. This study investigates the in vivo splicing phenotypes of mutations in the branch site consensus sequence of the U12-dependent intron F from a human NOL1 (P120) minigene. Intron F contains a fully consensus branch site sequence (UUCCUUAAC). Mutations at each position were analyzed for their effects on U12-dependent splicing in vivo. Mutations at most positions resulted in a significant reduction of correct U12-dependent splicing. Defects observed included increased unspliced RNA levels, the activation of cryptic U2-dependent 5' and 3' splice sites, and the activation of cryptic U12-dependent branch/3' splice sites. A strong correlation was observed between the predicted thermodynamic stability of the branch site: U12 snRNA interaction and correct U12-dependent splicing. The lack of a polypyrimidine tract between the branch site and 3' splice site of U12-dependent introns and the observed reliance on base-pairing interactions for correct U12-dependent splicing emphasize the importance of RNA/RNA interactions during U12-dependent intron recognition and proper splice site selection. 
 Question: Which is the branch site consensus sequence in U12-dependent introns?
Example Output: uuccuuaac

Example Input: Context: Rose Elliot (Irene Miracle), a poet living alone in New York City, discovers an ancient book called The Three Mothers. It tells of the existence of three evil sisters who rule the world with sorrow, tears, and darkness. The book, written by an architect named Varelli, reveals that the three dwell inside separate homes that had been specially designed and built for them by the architect in Rome, Freiburg, and New York. Rose suspects that she is living in one of the buildings and writes to her brother Mark (Leigh McCloskey), a music student in Rome, urging him to visit her. Using clues provided in Varelli's book as a guide, Rose searches the cellar of her building and discovers a hole in the floor which leads to a water-filled ballroom. After accidentally dropping her keys into the water, she enters the flooded room. Swimming under the surface, she sees a portrait bearing the words "Mater Tenebrarum" and is able to reclaim the keys. A putrid corpse suddenly rises from the depths, frightening her. She escapes, although a shadowy figure watches her leave the basement.In Rome, Mark attempts to read Rose's letter during class. He is distracted by the intense gaze of a beautiful student (Ania Pieroni). When the class ends she leaves suddenly; Mark follows, leaving the letter behind. His friend Sara (Eleonora Giorgi) picks up the letter, and eventually reads it. Horrified by the letter's contents, she takes a taxi to a library and locates a copy of The Three Mothers. While looking for an exit, Sara is attacked by a monstrous figure who recognizes the book. She throws the book to the ground and escapes. Later that night, she seeks the company of a neighbor named Carlo (Gabriele Lavia) and both are stabbed to death by a gloved killer. Mark discovers the bodies and two torn fragments from Rose's letter. After the police arrive, he walks out of Sara's apartment and sees a taxi slowly driving by. In it is the music student, staring at him intently once again.Mark telephones Rose but is unable to hear her clearly. He promises to visit just before the connection fails. Cut off, Rose sees two shadowy figures preparing to enter her apartment. She leaves through a back door, but is followed. In a decrepit room, she is grabbed from behind by a clawed assailant and brutally murdered.Upon arriving in New York, Mark meets some of the residents of Rose's building, including a nurse (Veronica Lazar) who is caring for the elderly Professor Arnold (Feodor Chaliapin, Jr.), a wheelchair-bound mute. Mark learns from the sickly Countess Elise (Daria Nicolodi) that Rose has disappeared. Elise explains how Rose had been acting strangely. After the two find blood on the carpet outside Rose's room, Mark follows the stains. He suddenly becomes ill and falls unconscious. Elise sees a black-robed figure dragging Mark away, but the figure suddenly stops and gives chase to Elise. She is attacked by dozens of cats, who bite and claw at her flesh. The hooded figure then stabs her to death. Mark staggers to the house's foyer where the nurse and caretaker (Alida Valli) put him to bed.The next day, Mark asks Kazanian (Sacha Pitoeff), the antique dealer who sold Rose the Three Mothers book, about Rose. However, the man provides no information. That night, Kazanian drowns several cats in a Central Park pond and accidentally falls into the water. Hundreds of rats from a nearby drain crawl all over him, gnawing his flesh. A hot dog vendor hears Kazanian's cries and rushes over. The man kills Kazanian with a knife.Carol, the caretaker, discovers the horribly mutilated corpse of Elise's butler (Leopoldo Mastelloni) in the Countess' apartment. Shocked, she drops a lit candle which starts a fire. Attempting to put out the flames, she becomes entangled in burning draperies and falls from a window to her death.Meanwhile, Mark uses a clue from Rose's letter to discover that beneath each floor is a secret 
 Question: Who is the caretaker?
Example Output: carol

Example Input: Context: England, 1694. Mrs Herbert (Janet Suzman) and her daughter Mrs Talmann (Anne-Louise Lambert) try to persuade Mr Neville (Anthony Higgins), an artist, to make a series of drawings of Mr and Mrs Herbert's house and estate. Mr Neville finally agrees when Mrs Herbert offers, in addition to paying for each drawing and giving him room and board while he draws, to sleep with him. (Oddly, she makes this offer in the presence of her husband's agent, Mr Noyes (Neil Cunningham), who is drawing up the contract.) Mrs Herbert intends the drawings to be a gift to her obnoxious and estranged husband, who dotes on his property and who is conveniently planning to be away from home while the drawings are created.Mr Neville inconveniences the entire household with detailed and stringent requirements for his 12 drawings. For specified periods every day, the views he has chosen must be kept clear of carriages, animals, smoking chimneys, and people -- except for the one that requires Mr Talmann (Hugh Fraser) to stand still and wear the same clothes for several days running.The atmosphere of the film is chilly; there's little indication that any of the characters like one another, and many of them are fairly hostile. Starting over the issue of Mr Talmann's wardrobe, Mr Talmann and Mr Neville snipe at one another continuously. Mr and Mrs Talmann have a bitter confrontation. It's hard to tell what the exaggerated costumes are meant to contribute: comically tall headpieces for the women, and for the men, very long, curly wigs -- waist-length, in some cases -- which, along with full-skirted coats, make them look like Edwardian schoolgirls.Mrs Herbert is distressed by the sexual part of her agreement and tries to break the contract; Mr Neville refuses. Mrs Talmann makes her own bargain for sexual favors with Mr Neville (which doesn't affect her mother's). Later, we learn that Mr Talmann is impotent -- and also that Mr Herbert doesn't believe that women should own property, so the inheritance of the estate depends on Mrs Talmann producing a son.Mr Herbert's injured horse turns up, and shortly thereafter his body is found in the moat. Mr Noyes, the agent, who as a young man wanted to marry Mrs Herbert, comes to her demanding assistance because he believes he will be suspected of murdering Mr Herbert. Mrs Herbert shows no interest in helping him, so Mr Noyes blackmails her: if she doesn't give him the drawings (why does he want the drawings?), he'll make the draughtsman's contract public, exposing her as an adulteress.Mrs Talmann observes that many of the drawings include objects that have no business being where they are: a ladder leading to Mrs Talmann's bedroom window; a pair of boots belonging to her husband; and several items of clothing belonging to Mr Herbert. Mrs Talmann implies that Mr Neville is planting clues related to the demise of Mr Herbert. But Mr Neville is clearly drawing what he sees, and we have no evidence that he's responsible for the presence of any of the misplaced objects.An odd feature of the landscape is a moving statue (Michael Feast), which turns up twined with vines against a wall, on the roof while Mrs Herbert and her guests are eating an outdoor meal in the foreground, and on a pedestal from which it first removes an obelisk.Having completed his contract and gone away, Mr Neville comes back for a visit. Mrs Herbert offers him one more tryst in exchange for one more drawing, and he agrees. He completes a view of an equestrian statue in the garden, though he draws the horse without its rider. It's not apparent whether this is because he can't see the rider -- the moving statue may not be visible to everyone -- or because Mr Neville is alluding to the death of Mr Herbert.Although his drawing is done, Mr Neville continues to sit by the statue. As it grows dark, he's surrounded by a group of masked gentlemen, most of whom are recognizable as members of the Herbert household or their
