Question: 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 Rose grabbed by?

Answer: clawed assailant


Question: Context: The Godfather Part II presents two parallel storylines. One involves Mafia chief Michael Corleone in 1958/1959 after the events of the first movie; the other is a series of flashbacks following his father, Vito Corleone from 1917 to 1925, from his youth in Sicily (1901) to the founding of the Corleone family in New York.The film begins in 1901, in the town of Corleone, Sicily, at the funeral of young Vito's father, Antonio Andolini, who has been murdered for an insult to the local Mafia lord, Don Ciccio. During the procession, Vito's older brother is murdered because he swore revenge on the Don. Vito's mother goes to Ciccio to beg for mercy, but he refuses, knowing that nine-year-old Vito will seek revenge later in life. The mother takes Ciccio hostage at knifepoint, allowing her son to escape, and Ciccio's men kill her. They search the town for the boy, but he is aided in his escape by the townspeople. Vito finds his way by ship to New York, and at Ellis Island an immigration agent chooses Vito's hometown of Corleone as his surname, and he is registered as "Vito Corleone".In 1958 in a scene similar to the opening of the first film, Michael Corleone (Al Pacino), Godfather of the Corleone family, deals with various business and family problems during an elaborate party at his Lake Tahoe, Nevada compound to celebrate his son's First Communion. In his office, Michael meets with corrupt Nevada Senator Pat Geary (G. D. Spradlin) to discuss the price of the gaming licenses for the hotel/casinos the Family is buying. Geary, who has obvious contempt for Michael and other Italian businessmen who are moving into his state to take advantage of gambling opportunities, promises to make Michael's acquisition of his gaming license a difficult process. Michael ends his conversation with Geary when he refuses to pay the outrageous fee Geary demands, telling the senator he'll get nothing.Michael also deals with his self-indulgent younger sister Connie (Talia Shire), who, although recently divorced from her second husband, is planning to marry a man named Merl Johnson (Troy Donahue) with no obvious means of support and of whom Michael disapproves. He also talks with Johnny Ola (Dominic Chianese), the right hand man of Jewish gangster Hyman Roth (Lee Strasberg), who is supporting Michael's move into the gambling industry. Belatedly, Michael deals with Frank "Five Angels" Pentangeli (Michael V. Gazzo), a business associate who took over Corleone caporegime Peter Clemenza's territory in New York City after his death, and now has problems with the Rosato Brothers, who are backed by Roth. Pentangeli leaves abruptly, after telling Michael "your father did business with Hyman Roth, your father respected Hyman Roth, but your father never trusted Hyman Roth."Later that night, Michael barely escapes an assassination attempt when his wife Kay (Diane Keaton) notices the bedroom window drapes are inexplicably open, which allows two unseen hitmen to spray the bedroom with bullets. The two hitman are found dead having been killed by a "mole" within the compound. Afterwards, Michael tells his lawyer and associate Tom Hagen (Robert Duvall) that the hit was made with the help of someone close, and that he must leave, entrusting all his power to Hagen to protect his family.Flashback: In 1917 New York City, the adult Vito Corleone (Robert De Niro) works in a grocery store in the Lower East side with his friend Genco Abbandando. The neighborhood is controlled by a member of the "The Black Hand," Don Fanucci (Gastone Moschin), who extorts protection payments from local businesses. One night, Vito's neighbor Clemenza (Bruno Kirby) asks him to hide a stash of guns for him, and later, to repay the favor, takes him to a fancy apartment where they commit their first felony together, stealing an elegant rug.The film flash-forwards to Michael's time. Michael meets with poushal Hyman Roth in Miami, Florida who tells Michael that he believes Frank Pentangeli was responsible for the assassination attempt, and that Pentangeli will pay for it 
 Question: Who visits Sicily for the first time since emigrating?

Answer: vito


Question: Context: Sometimes cells need to obtain energy from sugar, but there is no oxygen present to complete cellular respiration. In this situation, cellular respiration can be anaerobic, occurring in the absence of oxygen. In this process, called fermentation, only the first step of respiration, glycolysis, occurs, producing two ATP; no additional ATP is produced. Therefore, the organism only obtains the two ATP molecules per glucose molecule from glycolysis. Compared to the 36-38 ATP produced under aerobic conditions, anaerobic respiration is not a very efficient process. Fermentation allows the first step of cellular respiration to continue and produce some ATP, even without oxygen. Yeast (single-celled eukaryotic organisms) perform alcoholic fermentation in the absence of oxygen. The products of alcoholic fermentation are ethyl alcohol (drinking alcohol) and carbon dioxide gas. This process is used to make common food and drinks. For example, alcoholic fermentation is used to bake bread. The carbon dioxide bubbles allow the bread to rise and become fluffy. Meanwhile, the alcohol evaporates. In wine making, the sugars of grapes are fermented to produce wine. The sugars are the starting materials for glycolysis. Animals and some bacteria and fungi carry out lactic acid fermentation. Lactic acid is a waste product of this process. Our muscles perform lactic acid fermentation during strenuous exercise, since oxygen cannot be delivered to the muscles quickly enough. The buildup of lactic acid is believed to make your muscles sore after exercise. Bacteria that produce lactic acid are used to make cheese and yogurt. The lactic acid causes the proteins in milk to thicken. Lactic acid also causes tooth decay, because bacteria use the sugars in your mouth for energy. Pictured below are some products of fermentation ( Figure 1.1). Products of fermentation include cheese (lactic acid fermentation) and wine (alco- holic fermentation). Behind every fart is an army of gut bacteria undergoing some crazy biochemistry. These bacteria break down the remains of digested food through fermentation, creating gas in the process.
