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.

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 Output:
What is the name of the person that wanted to add a statement about the impending defeat of Germany?

Passage: The SSSI is designated as a Special Protection Area for birds for its variety of coastal habitats. The large breeding colonies of Sandwich terns and little terns, especially those at Blakeney Point and Scolt Head Island, are of "European importance" as defined in the Birds Directive, and the coast as a whole meets Natural England's criteria for nationally important populations of common terns, pied avocets and reedbed specialists like western marsh harriers, Eurasian bitterns and bearded reedlings. Other birds nesting in the wetlands include the northern lapwing, common redshank, and sedge, reed and Cetti's warblers. Ringed plovers and Eurasian oystercatchers lay their eggs on bare sand in the dunes. Little egrets, Eurasian spoonbills, ruffs and black-tailed godwits are present for much of the year, and the egret and spoonbill have both started nesting within the SSSI.In spring and early summer, migrant birds including the little gull, black tern, Temminck's stint and garganey may pass through on their way to breed elsewhere. In the autumn, birds arrive from the north; some, such as whimbrels, curlew sandpipers and little stints, just pausing for a few days to refuel before continuing south, others staying for the winter. Offshore, great and Arctic skuas, northern gannets and black-legged kittiwakes may pass close by in favourable winds. Large numbers of ducks winter along the coast, including many Eurasian wigeons, Eurasian teals, mallards and gadwalls, goldeneyes and northern pintails. Red-throated divers are usually on the sea, and brent geese feed on sea lettuce and other green algae. Barn owls and sometimes hen harriers quarter the marshes in winter, and snow bunting flocks can be found on the beaches. Thousands of geese, mainly pink-footed, roost at Holkham.The SSSI's north-facing east coast location can be favourable for huge numbers of migrating birds when the weather conditions are right. These may include vagrant rarities. A black-winged stilt, which acquired the nickname "Sammy", arrived at Titchwell in 1993 and became a permanent resident up to its disappearance in 2005. Other major rarities included a western sandpiper at Cley in 2012, a rufous-tailed robin at Warham Greens in 2011, and a black-winged pratincole at Titchwell in 2009.

Ex Output:
What is the nickname of the black-winged stilt that appeared in 1993?

Passage: The United States admitted more legal immigrants from 1991 to 2000, between ten and eleven million, than in any previous decade. In the most recent decade, the 10 million legal immigrants that settled in the U.S. represent roughly one third of the annual growth, as the U.S. population grew by 32 million (from 249 million to 281 million). By comparison, the highest previous decade was the 1900s, when 8.8 million people arrived, increasing the total U.S. population by one percent every year. Specifically, "nearly 15% of Americans were foreign-born in 1910, while in 1999, only about 10% were foreign-born."By 1970, immigrants accounted for 4.7 percent of the US population and rising to 6.2 percent in 1980, with an estimated 12.5 percent in 2009. As of 2010, 25% of US residents under age 18 were first- or second-generation immigrants. Eight percent of all babies born in the U.S. in 2008 belonged to illegal immigrant parents, according to a recent analysis of U.S. Census Bureau data by the Pew Hispanic Center.Legal immigration to the U.S. increased from 250,000 in the 1930s, to 2.5 million in the 1950s, to 4.5 million in the 1970s, and to 7.3 million in the 1980s, before resting at about 10 million in the 1990s. Since 2000, legal immigrants to the United States number approximately 1,000,000 per year, of whom about 600,000 are Change of Status who already are in the U.S. Legal immigrants to the United States now are at their highest level ever, at just over 37,000,000 legal immigrants. In reports in 2005-2006, estimates of illegal immigration ranged from 700,000 to 1,500,000 per year. Immigration led to a 57.4% increase in foreign born population from 1990 to 2000.While immigration has increased drastically over the last century, the foreign born share of the population is, at 13.4, only somewhat below what it was at its peak in 1910 at 14.7%. A number of factors may be attributed to the decrease in the representation of foreign born residents in the United States. Most significant has been the change in the composition of immigrants; prior to 1890, 82% of immigrants came from North and Western Europe. From 1891 to 1920, that number dropped to 25%, with a rise in immigrants from East, Central, and South Europe, summing up to 64%. Animosity towards these different and foreign immigrants rose in the United States, resulting in much legislation to limit immigration.Contemporary immigrants settle predominantly in seven states, California, New York, Florida, Texas, Pennsylvania, New Jersey and Illinois, comprising about 44% of the U.S. population as a whole. The combined total immigrant population of these seven states was 70% of the total foreign-born population in 2000.

Ex Output:

What states had 70% of the total immigrant population in 2000?
