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 Quirigua's pivotal victory over Copan in 738, K'ak' Tiliw Chan Yopaat rebuilt the main group in the image of Copan itself. Thus, the acropolis, palace, and ballcourt all lie at the southern end of the Great Plaza. The ceremonial centre is laid out around three plazas, the northernmost is the Great Plaza. This plaza measures 325 m (1,066 ft) from north to south and is the largest plaza in the whole Maya region. At the southern end of the Great Plaza is the Ballcourt Plaza, surrounded on three sides by structures associated with the acropolis. The Acropolis Plaza is a fully enclosed plaza within the acropolis itself. The area to the west of the Ballcourt Plaza was probably the riverside docking area and there is evidence that the southern part of the Great Plaza was a marketplace. A number of ceramic-lined wells have been excavated close to the site core, these were all built in the 8th century and although some continued in use into the 9th century, none are known to have been built that late.
1A-1 is an enormous platform forming the northern part of the Great Plaza. It measures 100 by 85 metres (328 by 279 ft) and rises 0.5 metres (20 in) above the level of the southern part of the plaza. It forms the northern portion of the Great Plaza, being built by K'ak' Tiliw Chan Yopaat when he extended the plaza northward. The platform was built from river cobbles and was paved with stone slabs. Platform 1A-1 supported the stelae A, C, D, E and F and Zoomorph B. The platform was built in two phases over about 20 years.
1A-3 is a large mound marking the northern edge of the Great Plaza. It originally measured 82.5 by 20 metres (271 by 66 ft) and was 7 metres (23 ft) high. A 63-metre (207 ft) wide stairway climbed the southern face of the structure from the plaza. The structure was later extended to the north but this second phase of construction was never finished.
The acropolis is the largest architectural complex at Quirigua, it lies at the southern limit of the ceremonial centre of the city. It is a complex construction, with new buildings and features being added over time. Construction of the acropolis began in 550 and continued through to 810 when the site was abandoned. The acropolis was a palace complex used primarily as an elite residence and for administrative purposes. The acropolis complex includes structures 1B-1, 1B-2, 1B-3, 1B-4, 1B-5 and 1B-6. Excavations of the acropolis encountered the fallen remains of corbel arches, but none are still standing.

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 "ship portrait" had a long history in maritime art, from medieval seals and coins to early engravings in the 15th century, and the plain side-on view of a ship under sail, often with no crew shown, was well established as the most effective way of recording the build of vessels. The Anthony Roll belongs to a genre of works that was intended to serve a dual role for the king and the military leadership: as reasonably informative overviews listing details of ships or strategic areas of coastlines they could be studied to determine strengths and weaknesses, and as boastful and lively depictions of Tudor military might they could be used to flatter the king, impress courtiers and impose martial authority on foreign ambassadors. Contemporary maps, or "plats", were routinely decorated with detailed pictures of ships, to mark bodies of water as much as to liven up the scenes. Such maps were common at the time, and were even embellished by artists if deemed too simple or drab. The navy was expanded during Henry VIII's reign, and he was known to take an interest in warships, as can be seen by the epic painting Embarkation of Henry VIII at Dover which portrayed, if rather unrealistically, the ships that took the 29-year-old king to the summit meeting with Francis I of France at the Field of the Cloth of Gold in 1520. This painting, recently dated to around 1545, has also been suggested as a likely source of inspiration to Anthony for his illustrations.There are three such plats depicting naval actions and expeditions that are attributed to Anthony: the route of Anne of Cleves from the Low Countries to England (1539), a French attack on a coastal fort (date unknown) and a French raid on Brighton (July 1545). The design of the ships in these paintings, especially that of the Brighton raid, closely match those in the rolls. It is not known exactly when work on the rolls began nor when it was finished. It is only certain that it was presented to the king the year it was dated, 1546. The inclusion of the Mary Rose that sank at the Battle of the Solent 19 July 1545 does not mean it was necessarily started before this date, since it was still considered possible that she could be raised even as late as 1549. The galleasses, the Antelope, Hart, Bull and Tiger, all present in the second roll, were still being built around March 1546, and the Hart was not at sea until October that year. At the same time the Galley Blanchard, captured from the French 18 May 1546 is not included.

Ex Output:
What is the name of the painting that has been suggested as a likely source of inspiration to Anthony for his illustrations?
