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: Most of the volcanoes in northern Chile are far from towns and inhabited areas and thus their activity does not create significant human hazards. Putre is constructed on pyroclastic deposits of the Taapaca, facing a threat from future eruptions. A highway (Chile Route 11 between La Paz and Arica) linking Bolivia with the Pacific Ocean is also in range on the southern flank, while the road to Visviri in Peru runs along the southwestern and western flanks. Additional areas within range of Taapaca are the towns of Socoroma and Zapahuira, as well as the Oruro Department in Bolivia. The danger is accentuated by the fact that Holocene activity has affected mainly the southwestern flank, where Putre is located. The average time between eruptions at Taapaca is about 450 years.Future activity at Taapaca could result in further sector collapses when magma is injected into the edifice and deforms it, to the point that the volcano becomes unstable. Likewise, if lava domes are extruded onto the volcano they could generate block and ash flows as well as both primary and secondary pyroclastic flows. Eruptions between April and November (when the volcano is covered by snow) might generate lahars, as could rainfall during the wet season between December and March; the latter type of lahar happens frequently on present-day Taapaca owing to the steep slopes of the volcano, although it usually results solely in road damage.The Chilean SERNAGEOMIN geological service monitors the volcano and shows a volcano hazard level for it. It also publishes a hazard map for Taapaca, which shows risk areas for lava bomb falls, pyroclastic flows and tephra fallout.
What two locations does Chile Route 11 link?

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.
What is the nickname of the black-winged stilt that appeared in 1993?

Passage: In 1982, Waters suggested a new musical project with the working title Spare Bricks, originally conceived as the soundtrack album for Pink Floyd The Wall. With the onset of the Falklands War, Waters changed direction and began writing new material. He saw Margaret Thatcher's response to the invasion of the Falklands as jingoistic and unnecessary, and dedicated the album to his late father. Immediately arguments arose between Waters and Gilmour, who felt that the album should include all new material, rather than recycle songs passed over for The Wall. Waters felt that Gilmour had contributed little to the band's lyrical repertoire. Michael Kamen, a contributor to the orchestral arrangements of The Wall, mediated between the two, also performing the role traditionally occupied by the then-absent Wright. The tension within the band grew. Waters and Gilmour worked independently; however, Gilmour began to feel the strain, sometimes barely maintaining his composure. After a final confrontation, Gilmour's name disappeared from the credit list, reflecting what Waters felt was his lack of songwriting contributions.Though Mason's musical contributions were minimal, he stayed busy recording sound effects for an experimental Holophonic system to be used on the album. With marital problems of his own, he remained a distant figure. Pink Floyd did not use Thorgerson for the cover design, Waters choosing to design the cover himself. Released in March 1983, The Final Cut went straight to number one in the UK and number six in the US. Waters wrote all the lyrics, as well as all the music on the album. Gilmour did not have any material ready for the album and asked Waters to delay the recording until he could write some songs, but Waters refused. Gilmour later commented: "I'm certainly guilty at times of being lazy ... but he wasn't right about wanting to put some duff tracks on The Final Cut." Rolling Stone magazine gave the album five stars, with Kurt Loder calling it "a superlative achievement ... art rock's crowning masterpiece". Loder viewed The Final Cut as "essentially a Roger Waters solo album".
What is the last name of the band member that designed the cover of the 1983 album?
