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.

[EX Q]: Passage: After selecting the music by Alexandrov for the national anthem, Stalin needed new lyrics. He thought that the song was short and, because of the Great Patriotic War, that it needed a statement about the impending defeat of Germany by the Red Army. The poets Sergey Mikhalkov and Gabriel El-Registan were called to Moscow by one of Stalin's staffers, and were told to fix the lyrics to Alexandrov's music. They were instructed to keep the verses the same, but to find a way to change the refrains which described "a Country of Soviets". Because of the difficulty of expressing the concepts of the Great Patriotic War in song, that idea was dropped from the version which El-Registan and Mikhalkov completed overnight. After a few minor changes to emphasize the Russian Motherland, Stalin approved the anthem and had it published on 7 November 1943, including a line about Stalin "inspir[ing] us to keep the faith with the people". The revised anthem was announced to all of the USSR on January 1, 1944 and became official on March 15, 1944.After Stalin's death in 1953, the Soviet government examined his legacy. The government began the de-Stalinization process, which included downplaying the role of Stalin and moving his corpse from Lenin's Mausoleum to the Kremlin Wall Necropolis. In addition, the anthem lyrics composed by Mikhalkov and El-Registan were officially scrapped by the Soviet government in 1956. The anthem was still used by the Soviet government, but without any official lyrics. In private, this anthem became known the "Song Without Words". Mikhalkov wrote a new set of lyrics in 1970, but they were not submitted to the Presidium of the Supreme Soviet until May 27, 1977. The new lyrics, which eliminated any mention of Stalin, were approved on 1 September, and were made official with the printing of the new Soviet Constitution in October 1977. In the credits for the 1977 lyrics, Mikhalkov was mentioned, but references to El-Registan, who died in 1945, were dropped for unknown reasons.
[EX A]: What is the name of the person that wanted to add a statement about the impending defeat of Germany?

[EX Q]: Passage: The open waters are inhabited by fishes, molluscs and crustaceans living on sea grasses or who prey on each other. The shallowness of the lagoon makes it suitable habitat for diving birds such as anhinga, cormorants and diving ducks. The bay also provides habitat for juvenile sea animals that have left the shelter of the mangrove belts.  Manatees frequent the quiet waters of the bay. The bay has a year-round population of double-crested cormorants. Winter residents include northern gannets, American white pelicans and common loons. The bay also has a resident population of common bottlenose dolphins.Biscayne Bay is a shallow lagoon with little vertical density or salinity gradient due to its lack of depth. Instead of a vertical gradient, the bay shows a horizontal density gradient, with fresh water entering from the drainage canals on the west side and seawater entering through gaps in the keys and through the safety valve section of shoals. Bay salinity reaches a peak in June. Changes in the salinity pattern of the bay have had negative effects on formerly abundant species such as red drum. Biscayne Bay and Florida Bay are major nurseries for red grouper and gray snapper. The bottom of the lagoon hosts sponges and soft corals in places where grasses cannot not grow. Three primary species of seagrass are found in the park: turtlegrass, shoal grass and manatee grass. The endangered Johnson's seagrass is also found in small quantities in the bay, which is at the southern end of the grass's range. Roughly 75 percent of the central bay floor is covered by grasses. Scarring of seagrass beds by vessel groundings or propellers is a significant problem. About 200 such incidents are documented each year, with full re-growth requiring up to 15 years. The bay is also affected by commercial shrimp trawling, which is permitted in park waters.  The passage of roller-frame trawl nets does not harm grasses, but damages soft corals and sponges.
[EX A]: What is the name of the entity that provides habitat for juvenile sea animals that have left the shelter of the mangrove belts?

[EX Q]: Passage: Frank Chambers a drifter, stops at a depression-era rural California diner for a meal and ends up working there. The diner is operated by a young, beautiful woman, Cora Smith, and her much older husband, Nick Papadakis, a hardworking but unimaginative immigrant from Greece.
Frank and Cora start to have an affair soon after they meet. Cora is tired of her situation, married to an older man she does not love, and working at a diner that she wishes to own and improve. She and Frank scheme to murder Nick to start a new life together without her losing the diner. Their first attempt at the murder is a failure, but Nick is not even aware they tried to kill him, so goes about living his life as usual. Frank and Cora succeed with their next attempt.
The local prosecutor suspects what has actually occurred but does not have enough evidence to prove it. As a tactic intended to get Cora and Frank to turn on one another, he tries only Cora for the crime.
Although they turn against each other, a clever ploy from Cora's lawyer, Katz, prevents Cora's full confession from coming into the hands of the prosecutor. With the tactic having failed to generate any new evidence for the prosecution, Cora benefits from a deal in which she pleads guilty to manslaughter and is sentenced to probation.
Months later, Frank has an affair with Madge Gorland while Cora is out of town. When Cora returns, she tells Frank she is pregnant. That night, Katz's assistant, Kennedy, appears at their door and threatens to expose them unless they give him $10,000. Enraged, Frank beats Kennedy up and strong-arms him into giving up the evidence against them.
[EX A]:
What are the full names of the people who hire Frank?
