In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Question: Passage: The film opens at Burger-Matic, where Henry Lever orders a milkshake at the drive-thru. At the window, he tells the attendant, Sally Jackson, that his wife knows about their affair. She asks him if he has also told his wife about her pregnancy. On his way home, he encounters a ferocious wind. It turns out to be an attack helicopter, which runs him off the road. In a panic, he flees through the woods and drops his heart medication. At an outdoor chapel, he sits on a bench as the helicopter hovers in front of him. The pilot, Angus Montier, shoots at the ground near him despite the protests of his copilot and brother, Dorian. The shots scare him enough to cause a fatal heart attack.
Throughout their attack, Dorian and Angus can hear the chatter of Sally and her coworkers. Likewise, they can hear the helicopter pilots on their headsets. The next day, the police inform Beatrice Lever that Henry has died. She appears shocked and crestfallen, when Dorian and Angus arrive. It quickly becomes clear that she encouraged her sons to scare him to death. She is also furious about his affair, and wants revenge on his mistress. Angus and Dorian are worried that the people they heard on the radio might have overheard enough to connect them to his death. They quickly deduce that Burger-Matic is the only location close enough to have been on the same frequency. Angus goads Dorian into getting a job there to ensure that no one is wise to their crime.
Sally is heartbroken at the news about Henry. At work, Dorian bonds with her quickly. He gives her a model helicopter for her baby, and he explains that he and Angus fly them as reservists for the National Guard. She asks him to accompany her to lamaze class, since she doesn't have a partner. Eventually, he takes her to the base to see the helicopter that he flies. As she sits in the cockpit, she tells him about Henry.

Answer: What are the full names of the two people having an affair?


Question: Passage: When charter-boat skipper Jack O'Conner finds a gold Spanish dollar off the Florida Keys, he decides to go in search of a legendary hoard of Spanish doubloons sunk during the "Hundred Years Storm" of 1780. For, as Jack's friend Cap'n Billau reveals, the coin bears a clue to the treasure's whereabouts – one of four islands etched by the infamous pirate, Jacques Un-Oeil upon the original doubloon. At Billau's urging, Jack tracks down the two beautiful women who unknowingly hold the remaining clues.
Streetwise Sandy Sequoia's piece of eight came from her murdered drug dealer boyfriend in Miami. And lonely-heart Portia Pennington inherited her coin from her merchant tycoon grandfather, who died at sea in the "Hundred Years Storm" of 1893, while hunting for the lost gold.
Jack convinces the girls to go in search of the pirate treasure with him. But first, the two must learn to crew his 76' schooner; and then, all three adventurers must learn to trust one another, if they expect to navigate the treacheries of love and the unpredictable Caribbean.
As Jack introduces the girls to life at sea, he starts to fall in love with Sandy. All seems to be going well, until Jack discovers Sandy with drugs on his boat – a kilo of her dead boyfriend's cocaine (which she has steadily been using since coming aboard). He has Portia dump the coke overboard; and while Sandy wrestles to overcome her addiction, Jack turns his attentions to Portia.
When Sandy and Portia realize that Jack has seduced each of them in turn and convinced each to reveal to him the name of the island on her coin, they turn on him. Feeling betrayed and realizing that they no longer need Jack in order to sail the boat or find the gold, they maroon him on a small island and go after the sunken treasure themselves.

Answer: What is the last name of the person who is friends with Cap'n Billau?


Question: Passage: Following a brief post-war downturn, boom times returned to Jerome in the 1920s. Copper prices rose to 24 cents a pound in 1929, and United Verde and UVX operated at near capacity. Wages rose, consumers spent, and the town's businesses—including five automobile dealerships—prospered. United Verde, seeking stable labor relations, added disability and life insurance benefits for its workers and built a baseball field, tennis courts, swimming pools, and a public park in Jerome. Both companies donated to the Jerome Public Library and helped finance projects for the town's schools, churches, and hospitals.In 1930, after the start of the Great Depression, the price of copper fell to 14 cents a pound. In response, United Verde began reducing its work force; UVX operated at a loss, and the third big mine, Verde Central, closed completely. The price of copper fell further in 1932 to 5 cents a pound, leading to layoffs, temporary shut-downs, and wage reductions in the Verde District. In 1935, the Clark family sold United Verde to Phelps Dodge, and in 1938 UVX went out of business.
Meanwhile, a subsidence problem that had irreparably damaged at least 10 downtown buildings by 1928 worsened through the 1930s. Dozens of buildings, including the post office and jail, were lost as the earth beneath them sank away. Contributing causes were geologic faulting in the area, blast vibrations from the mines, and erosion that may have been exacerbated by vegetation-killing smelter smoke.Mining continued at a reduced level in the Verde District until 1953, when Phelps Dodge shut down the United Verde Mine and related operations. Jerome's population subsequently fell below 100. To prevent the town from disappearing completely, its remaining residents turned to tourism and retail sales. They organized the Jerome Historical Society in 1953 and opened a museum and gift shop.To encourage tourism, the town's leaders sought National Historic Landmark status for Jerome; it was granted by the federal government in 1967. In 1962, the heirs of James Douglas donated the Douglas mansion, above the UVX mine site, to the State of Arizona, which used it to create Jerome State Historic Park. By sponsoring music festivals, historic-homes tours, celebrations, and races, the community succeeded in attracting visitors and new businesses, which in the 21st century include art galleries, craft stores, wineries, coffee houses, and restaurants.

Answer:
What year was the town that had its population dip under 100 granted National Historic Landmark status?
