[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: What causes clouds to form? And in general, how does matter change from one state to another? As you may have guessed, changes in energy are involved. Changes of state are physical changes in matter. They are reversible changes that do not involve changes in matters chemical makeup or chemical properties. Common changes of state include melting, freezing, sublimation, deposition, condensation, and vaporization. These changes are shown in Figure 4.18. Each is described in detail below. Energy is always involved in changes of state. Matter either loses or absorbs energy when it changes from one state to another. For example, when matter changes from a liquid to a solid, it loses energy. The opposite happens when matter changes from a solid to a liquid. For a solid to change to a liquid, matter must absorb energy from its surroundings. The amount of energy in matter can be measured with a thermometer. Thats because a thermometer measures temperature, and temperature is the average kinetic energy of the particles of matter. You can learn more about energy, temperature, and changes of state at this URL: [Link] Think about how you would make ice cubes in a tray. First you would fill the tray with water from a tap. Then you would place the tray in the freezer compartment of a refrigerator. The freezer is very cold. What happens next? The warmer water in the tray loses heat to the colder air in the freezer. The water cools until its particles no longer have enough energy to slide past each other. Instead, they remain in fixed positions, locked in place by the forces of attraction between them. The liquid water has changed to solid ice. Another example of liquid water changing to solid ice is pictured in Figure 4.19. The process in which a liquid changes to a solid is called freezing. The temperature at which a liquid changes to a solid is its freezing point. The freezing point of water is 0C (32F). Other types of matter may have higher or lower freezing points. For example, the freezing point of iron is 1535C. The freezing point of oxygen is -219C. If you took ice cubes out of a freezer and left them in a warm room, the ice would absorb energy from the warmer air around it. The energy would allow the particles of frozen water to overcome some of the forces of attraction holding them together. They would be able to slip out of the fixed positions they held as ice. In this way, the solid ice would turn to liquid water. The process in which a solid changes to a liquid is called melting. The melting point is the temperature at which a solid changes to a liquid. For a given type of matter, the melting point is the same as the freezing point. What is the melting point of ice? What is the melting point of iron, pictured in Figure 4.20? If you fill a pot with cool tap water and place the pot on a hot stovetop, the water heats up. Heat energy travels from the stovetop to the pot, and the water absorbs the energy from the pot. What happens to the water next? If water gets hot enough, it starts to boil. Bubbles of water vapor form in boiling water. This happens as particles of liquid water gain enough energy to completely overcome the force of attraction between them and change to the gaseous state. The bubbles rise through the water and escape from the pot as steam. The process in which a liquid boils and changes to a gas is called vaporization. The temperature at which a liquid boils is its boiling point. The boiling point of water is 100C (212F). Other types of matter may have higher or lower boiling points. For example, the boiling point of table salt is 1413C. The boiling point of nitrogen is -196C. A liquid can also change to a gas without boiling. This process is called evaporation. It occurs when particles at the exposed surface of a liquid absorb just enough energy to pull away from the liquid and escape into the air. This happens faster at warmer temperatures. Look at the puddle in Figure 4.21.

condensation.
