[EX Q]: Context: In 1953, 10-year-old Larry Flynt is selling moonshine in Kentucky. Twenty years later, Flynt (Woody Harrelson) and his younger brother, Jimmy (Brett Harrelson) run the Hustler Go-Go club in Cincinnati. With profits down, Flynt decides to publish a newsletter for the club, the first Hustler magazine, with nude pictures of women working at the club. The newsletter soon becomes a full-fledged magazine, but sales are weak. In 1975, after Hustler publishes nude pictures of former first lady Jackie Kennedy Onassis, sales take off.Flynt becomes smitten with Althea Leasure (Courtney Love), a stripper who works at one of his clubs. With Althea and Jimmy's help, Flynt makes a fortune from sales of Hustler. With his success comes enemies - as he finds himself a hated figure of anti-pornography activists. He argues with the activists, saying that "murder is illegal, but if you take a picture of it you may get your name in a magazine or maybe win a Pulitzer Prize". "However", he continues, "sex is legal, but if you take a picture of that act, you can go to jail". He becomes involved in several prominent court cases, and befriends a young lawyer, Alan Isaacman (Edward Norton). In 1975, Flynt loses a smut-peddling court decision in Cincinnati but is released from jail soon afterwards on a technicality. Ruth Carter Stapleton (Hanover), a Christian activist and sister of President Jimmy Carter, seeks out Flynt and urges him to give his life to Jesus. Flynt seems moved and starts letting his newfound religion influence everything in his life, including Hustler content.In 1978, during another trial in Georgia, Flynt and Isaacman are both shot by a man with a rifle while they walk outside a courthouse. Isaacman recovers, but Flynt is paralyzed from the waist down and uses a wheelchair for the rest of his life. Wishing he was dead, Flynt renounces God. Because of the emotional and physical pain, he moves to Beverly Hills, California and spirals down into depression and drug use. During this time, Althea also becomes addicted to painkillers and morphine.In 1983, Flynt undergoes back surgery to deaden several nerves, and as a result, feels rejuvenated. He returns to an active role with the publication, which, in his absence, had been run by Althea and Jimmy. That same year, Flynt is soon in court again for leaking videos relating to the John DeLorean entrapment case, and during his courtroom antics, he fires Isaacman, then throws an orange at the judge. He later wears an American flag as an adult diaper along with an army helmet, and wears T-shirts with provocative messages such as "I Wish I Was Black" and "Fuck This Court." After spitting water at the judge Flynt is sent to a psychiatric ward, where he sinks into depression again. He is diagnosed with having bipolar disorder and forced to take treatment.During this time, Flynt publishes a satirical parody ad in which Christian fundamentalist preacher Jerry Falwell tells of a sexual encounter with his mother. Falwell sues for libel and emotional distress. Flynt countersues for copyright infringement, because Falwell copied his ad. The case goes to trial in December 1984, but the decision is mixed, as Flynt is found guilty of inflicting emotional distress but not libel.By that time, Althea has contracted HIV, which proceeds to AIDS. Some time later in 1987, Flynt finds her dead in the bathtub, having drowned. Flynt presses Isaacman to appeal the Falwell decision to the Supreme Court of the United States. Isaacman refuses, saying Flynt's courtroom antics humiliated him. Flynt pleads with him, saying that he "wants to be remembered for something meaningful". Isaacman agrees and argues the "emotional distress" decision in front of the Supreme Court, in the case Hustler Magazine v. Falwell in 1988. With Flynt in the courtroom, the court overturns the original verdict in a unanimous decision. After the trial, Flynt is alone in his bedroom watching old videotapes of a healthy Althea.
Question: Who copied Flynts ad?
[EX A]: falwell

[EX Q]: 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?
[EX A]: clawed assailant

[EX Q]: Context: The Clean Air Act of 1970 and the amendments since then have done a great job in requiring people to clean up the air over the United States. Emissions of the six major pollutants regulated by the Clean Air Act carbon monoxide, lead, nitrous oxides, ozone, sulfur dioxide, and particulates have decreased by more than 50%. Cars, power plants, and factories individually release less pollution than they did in the mid-20th century. But there are many more cars, power plants, and factories. Many pollutants are still being released and some substances have been found to be pollutants that were not known to be pollutants in the past. There is still much work to be done to continue to clean up the air. Reducing air pollution from vehicles can be done in a number of ways. Breaking down pollutants before they are released into the atmosphere. Motor vehicles emit less pollution than they once did because of catalytic converters (Figure 1.1). Catalytic converters contain a catalyst that speeds up chemical reactions and breaks down nitrous oxides, carbon monoxide, and VOCs. Catalytic converters only work when they are hot, so a lot of exhaust escapes as the car is warming up. Catalytic converters are placed on mod- ern cars in the United States. Making a vehicle more fuel efficient. Lighter, more streamlined vehicles need less energy. Hybrid vehicles have an electric motor and a rechargeable battery. The energy that would be lost during braking is funneled into charging the battery, which then can power the car. The internal combustion engine only takes over when power in the battery has run out. Hybrids can reduce auto emissions by 90% or more, but many models do not maximize the possible fuel efficiency of the vehicle. A plug-in hybrid is plugged into an electricity source when it is not in use, perhaps in a garage, to make sure that the battery is charged. Plug-in hybrids run for a longer time on electricity and so are less polluting than regular hybrids. Plug-in hybrids began to become available in 2010. Developing new technologies that do not use fossil fuels. Fueling a car with something other than a liquid organic-based fuel is difficult. A fuel cell converts chemical energy into electrical energy. Hydrogen fuel cells harness the energy released when hydrogen and oxygen come together to create water (Figure 1.2). Fuel cells are extremely efficient and they produce no pollutants. But developing fuel-cell technology has had many problems and no one knows when or if they will become practical. Pollutants are removed from the exhaust streams of power plants and industrial plants before they enter the atmo- sphere. Particulates can be filtered out, and sulfur and nitric oxides can be broken down by catalysts. Removing these oxides reduces the pollutants that cause acid rain. Particles are relatively easy to remove from emissions by using motion or electricity to separate particles from the gases. Scrubbers remove particles and waste gases from exhaust using liquids or neutralizing materials (Figure 1.3). Gases, such as nitrogen oxides, can be broken down at very high temperatures. A hydrogen fuel-cell car looks like a gasoline-powered car. Scrubbers remove particles and waste gases from exhaust. Gasification is a developing technology. In gasification, coal (rarely is another organic material used) is heated to extremely high temperatures to create syngas, which is then filtered. The energy goes on to drive a generator. Syngas releases about 80% less pollution than regular coal plants, and greenhouse gases are also lower. Clean coal plants do not need scrubbers or other pollution control devices. Although the technology is ready, clean coal plants are more expensive to construct and operate. Also, heating the coal to high enough temperatures uses a great deal of energy, so the technology is not energy efficient. In addition, large amounts of the greenhouse gas CO2 are still released with clean coal technology. Nonetheless, a few of these plants are operating in the United States and around the world. How can air pollution be reduced? Using less fossil fuel is one way to lessen pollution. Some examples of ways to conserve fossil fuels are: Riding a bike or walking instead of driving

[EX A]:
electrical energy
