[Q]: Generate a question that has the following answer: "Klaatu barada nikto" for the following movie plot: When a flying saucer lands in Washington, D.C., the Army quickly surrounds the spaceship. A humanoid (Michael Rennie) emerges, announcing that he has come in peace. As he advances, he unexpectedly opens a small device and is shot by a nervous soldier. A tall robot emerges from the saucer and quickly disintegrates the soldiers' weapons with an energy ray. The alien orders the robot, Gort, to stop. He explains that the broken device was a gift for the President, which would have enabled him "to study life on the other planets". The alien is taken to Walter Reed Hospital, where he reveals his name: Klaatu. After surgery, Klaatu uses a salve to quickly heal himself. Meanwhile, the military is unable to enter his saucer; Gort stands outside, silent and unmoving. Klaatu tells the President's secretary, Mr. Harley (Frank Conroy), that he has a message that must be delivered to all the world's leaders simultaneously. Harley tells him that such a meeting in the current political climate is impossible. Klaatu suggests that he be allowed to go among humans to better understand their "unreasoning suspicions and attitudes". Harley rejects the proposal and leaves Klaatu under guard. Klaatu escapes and lodges at a boarding house as "Mr. Carpenter", the name on the dry cleaner's tag on the suit he "borrowed". Among the residents are young widow Helen Benson (Patricia Neal) and her son Bobby (Billy Gray). The next morning, Klaatu listens to the boarders speculate about why the alien has come. While Helen and her boyfriend Tom Stephens (Hugh Marlowe) go out, Klaatu babysits Bobby. The boy takes Klaatu on a tour of the city, including a visit to his father's grave in Arlington National Cemetery; Klaatu learns that most of those buried there were killed in wars. The two visit the Lincoln Memorial, then the heavily guarded spaceship. Klaatu asks Bobby who is the greatest living person; Bobby suggests Professor Barnhardt (Sam Jaffe), who lives in the capital. Bobby takes Klaatu to Barnhardt's home, but the professor is absent....

[Q]: Generate a question that has the following answer: Substance D for the following movie plot: The United States has lost the war on drugs. Substance D, a powerful and dangerous drug that causes bizarre hallucinations, has swept the country. Approximately 20% of the total population is addicted. In response, the government has developed an invasive, high-tech surveillance system and a network of undercover officers and informants. Bob Arctor is one of these undercover agents, assigned to immerse himself in the drug's underworld and infiltrate the supply chain. Sometime in the past, Arctor was abandoned by his wife and two children, leaving him alone in a now-rundown suburban house in Anaheim, California; the house has since been repopulated by Arctor's two drug-addicted, layabout housemates: Luckman and Barris. The three spend their days intoxicated and having long, paranoiac conversations. At the police station, Arctor maintains privacy by wearing a "scramble suit" that constantly changes every aspect of his appearance and he is known only by the code name "Fred." Arctor's senior officer, "Hank", and all other undercover officers, also wear scramble suits, protecting their identities even from each other. Since going undercover, Arctor himself has become addicted to Substance D and he has befriended the main woman he has been spying on: a cocaine addict and Substance D supplier named Donna. Arctor hopes to purchase large enough quantities of Substance D from Donna that she is forced to introduce him to her own supplier, but he has also developed seemingly unrequited romantic feelings towards her. At work, Hank orders Arctor to step up surveillance on Donna and her associates; however, Arctor's house is now at the center of his own investigation, since this is where Donna and the other addicts in her and Arctor's life now spend most of their time. Hank names Bob Arctor as the suspected ringleader, and thus orders Arctor to spy on himself. Arctor, therefore, has to even more carefully plan his double life, though his prolonged use of Substance D is damaging his brain, causing him to sometimes forget his...
