[Q]: Context: As elderly people go about their day in Manhattan, Harry walks along a sidewalk with his tabby cat Tonto on a leash, quoting Shakespeare's "King Lear" as he goes. Harry stops in at a grocer, buys some good food for his cat, and jokes that his sexual days are over.Next Harry meets his old friend Jacob on a bench, and tells him that his apartment building is being torn down to build a parking lot. Jacob complains about capitalists, and reassures Harry that he could always move in with him.On the way home, a kid tries to steal Harry's groceries and knocks him down. Harry is helped up by Leroy, his building super.Harry gets into his apartment and talks to Tonto, lamenting that he's been mugged four times in the past year, and that the whole city is getting run down.Some time later, police show up to forcibly remove Harry and his furniture from the building. Harry continues to spout "King Lear" while his son Burt arrives to pick him up.Harry goes to live with Burt and his wife and two grown sons in the suburbs. His younger grandson, Norman, has taken a vow of silence, leading to obvious tension with his brother and parents. Harry later asks Norman for the books that explain his beliefs.Harry goes back to his familiar bench to talk with Jacob, and they both agree it's been a long time since either has been with a woman. Jacob reminisces about his first sexual encounter with a servant girl when he was 14.Harry invites Leroy to dinner at Burt's house, and he plays the piano while Leroy dances to the tune. Leroy later comments that he lives with his 90-year-old mother and can't find a new job, which leads Burt's wife to question why Harry is not getting help from his two other kids.Knowing that he is a burden to Burt, Harry goes to look for his own apartment, but finds that the place he wants will not take cats. He then tells Burt he is going to Chicago to visit Shirley, Burt's sister, but before he leaves he stops at a city morgue to identify the body of Jacob, who has died with no relatives. Harry cries after recalling Jacob's story of losing his virginity.Burt takes Harry to the airport, but Harry soon learns that he can't go through security with Tonto, so he takes a cab to get a bus. Along the route, Harry asks the bus driver to stop so that Tonto can relieve himself, whereupon the cat runs away across a cemetery. The bus driver leaves Harry behind with his luggage, and when Tonto returns, Harry scolds him.Harry walks to a used car lot and buys an old Chevy for $250. He then checks into a motel and calls Burt to tell him what has happened, realizing in the process that his driver's license expired in 1958.Harry drives west rather slowly, with Tonto on the dashboard, recalling how he wanted to drive across the country when he was younger, but his wife and kids came along. He remembers they had many good times though. He confesses to Tonto that he has a great fear of pain, and that when he dies he would like to go quickly rather than the slow way his wife Annie died.Harry picks up two young hitchhikers, one of whom soon gets another ride, while the other a girl named Ginger continues west with Harry. She claims she is 16, and is running away from home to a commune in Boulder.Harry and Ginger get a motel for the night, and after she comes out of the bathroom half-naked, Harry is prompted to recall the first girl he loved, Jessie, whom he has not seen in 50 years. Ginger suggests that they go to see her, even though it's out of their way, and they eventually find her in a nursing home.At first Harry thinks Jessie remembers him, but her thoughts are marked by senility; she calls him Alex yet remembers his wife Annie. Then she suddenly asks Harry to dance, which they do while Ginger looks on.Harry

[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?
[A]: falwell


[Q]: Context: Viroids, subviral pathogens of plants, are composed of a single-stranded circular RNA of 246-399 nucleotides. Within the 27 viroids sequenced, avocado sunblotch, peach latent mosaic and chrysanthemum chlorotic mottle viroids (ASBVd, PLMVd and CChMVd, respectively) can form hammerhead structures in both of their polarity strands. These ribozymes mediate self-cleavage of the oligomeric RNAs generated in the replication through a rolling circle mechanism, whose two other steps are catalyzed by an RNA polymerase and an RNA ligase. ASBVd, and presumably PLMVd and CChMVd, replicate and accumulate in the chloroplast, whereas typical viroids replicate and accumulate in the nucleus. PLMVd and CChMVd do not adopt a rod-like or quasi rod-like secondary structure as typical viroids do but have a highly branched conformation. A pathogenicity determinant has been mapped in a defined region of the CChMVd molecule. 
 Question: Which are the smallest known subviral pathogens of plants?
[A]:
viroids
