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 Input:
Passage: The Rosetta Stone is listed as "a stone of black granodiorite, bearing three inscriptions ... found at Rosetta" in a contemporary catalogue of the artefacts discovered by the French expedition and surrendered to British troops in 1801. At some period after its arrival in London, the inscriptions on the stone were coloured in white chalk to make them more legible, and the remaining surface was covered with a layer of carnauba wax designed to protect the Rosetta Stone from visitors' fingers. This gave a dark colour to the stone that led to its mistaken identification as black basalt. These additions were removed when the stone was cleaned in 1999, revealing the original dark grey tint of the rock, the sparkle of its crystalline structure, and a pink vein running across the top left corner. Comparisons with the Klemm collection of Egyptian rock samples showed a close resemblance to rock from a small granodiorite quarry at Gebel Tingar on the west bank of the Nile, west of Elephantine in the region of Aswan; the pink vein is typical of granodiorite from this region.The Rosetta Stone is 1,123 millimetres (3 ft 8 in) high at its highest point, 757 mm (2 ft 5.8 in) wide, and 284 mm (11 in) thick. It weighs approximately 760 kilograms (1,680 lb). It bears three inscriptions: the top register in Ancient Egyptian hieroglyphs, the second in the Egyptian Demotic script, and the third in Ancient Greek. The front surface is polished and the inscriptions lightly incised on it; the sides of the stone are smoothed, but the back is only roughly worked, presumably because this would have not been visible when it was erected.

Ex Output:
How many kilograms does the Rosetta Stone weigh?

Passage: All whales are carnivorous and predatory. Odontocetes, as a whole, mostly feed on fish and cephalopods, and then followed by crustaceans and bivalves. All species are generalist and opportunistic feeders. Mysticetes, as a whole, mostly feed on krill and plankton, followed by crustaceans and other invertebrates. A few are specialists. Examples include the blue whale, which eats almost exclusively krill, the minke whale, which eats mainly schooling fish, the sperm whale, which specialize on squid, and the grey whale which feed on bottom-dwelling invertebrates. The elaborate baleen "teeth" of filter-feeding species, mysticetes, allow them to remove water before they swallow their planktonic food by using the teeth as a sieve. Usually whales hunt solitarily, but they do sometimes hunt cooperatively in small groups. The former behaviour is typical when hunting non-schooling fish, slow-moving or immobile invertebrates or endothermic prey. When large amounts of prey are available, whales such as certain mysticetes hunt cooperatively in small groups. Some cetaceans may forage with other kinds of animals, such as other species of whales or certain species of pinnipeds.Large whales, such as mysticetes, are not usually subject to predation, but smaller whales, such as monodontids or ziphiids, are. These species are preyed on by the killer whale or orca. To subdue and kill whales, orcas continuously ram them with their heads; this can sometimes kill bowhead whales, or severely injure them. Other times they corral the narwhals or belugas before striking. They are typically hunted by groups of 10 or fewer orcas, but they are seldom attacked by an individual. Calves are more commonly taken by orcas, but adults can be targeted as well.These small whales are also targeted by terrestrial and pagophilic predators. The polar bear is well adapted for hunting Arctic whales and calves. Bears are known to use sit-and-wait tactics as well as active stalking and pursuit of prey on ice or water. Whales lessen the chance of predation by gathering in groups. This however means less room around the breathing hole as the ice slowly closes the gap. When out at sea, whales dive out of the reach of surface-hunting orcas. Polar bear attacks on belugas and narwhals are usually successful in winter, but rarely inflict any damage in summer.

What is the overarching name of the broader species that all are generalist and opportunistic feeders?

Passage: Bowie moved to the US in 1974, initially staying in New York City before settling in Los Angeles. Diamond Dogs (1974), parts of which found him heading towards soul and funk, was the product of two distinct ideas: a musical based on a wild future in a post-apocalyptic city, and setting George Orwell's 1984 to music. The album went to number one in the UK, spawning the hits "Rebel Rebel" and "Diamond Dogs", and No. 5 in the US. To promote it, Bowie launched the Diamond Dogs Tour, visiting cities in North America between June and December 1974. Choreographed by Toni Basil, and lavishly produced with theatrical special effects, the high-budget stage production was filmed by Alan Yentob. The resulting documentary, Cracked Actor, featured a pasty and emaciated Bowie: the tour coincided with the singer's slide from heavy cocaine use into addiction, producing severe physical debilitation, paranoia, and emotional problems. He later commented that the accompanying live album, David Live, ought to have been titled "David Bowie Is Alive and Well and Living Only in Theory". David Live nevertheless solidified Bowie's status as a superstar, charting at No. 2 in the UK and No. 8 in the US. It also spawned a UK No. 10 hit in Bowie's cover of Eddie Floyd's "Knock on Wood". After a break in Philadelphia, where Bowie recorded new material, the tour resumed with a new emphasis on soul.
Matters came to a head in London in May in what became known as the "Victoria Station incident". Arriving in an open-top Mercedes convertible, Bowie waved to the crowd in a gesture that some alleged was a Nazi salute, which was captured on camera and published in NME. Bowie said the photographer caught him in mid-wave. He later blamed his pro-fascism comments and his behaviour during the period on his addictions and the character of the Thin White Duke. "I was out of my mind, totally crazed. The main thing I was functioning on was mythology ... that whole thing about Hitler and Rightism ... I'd discovered King Arthur". According to playwright Alan Franks, writing later in The Times, "he was indeed 'deranged'. He had some very bad experiences with hard drugs." Bowie's cocaine addiction, which had motivated these controversies, had much to do with his time living in Los Angeles, a city which alienated him. Discussing his flirtations with fascism in a 1980 interview with NME, Bowie explained that Los Angeles was "where it had all happened. The fucking place should be wiped off the face of the Earth. To be anything to do with rock and roll and go and live in Los Angeles is, I think, just heading for disaster. It really is."After recovering from addiction, Bowie apologised for these statements, and throughout the 1980s and '90s criticised racism in European politics and the American music industry. Nevertheless, Bowie's comments on fascism, as well as Eric Clapton's alcohol-fuelled denunciations of Pakistani immigrants in 1976, led to the establishment of Rock Against Racism.

Ex Output:
What is the name of the song that was a top ten hit in the UK from the David Live album?
