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.

Input: Consider Input: Passage: Two groups of goldcrest taxa are found on the Atlantic islands of Macaronesia. Birds on the Canary Islands are ancient colonists, whereas those on The Azores are of more recent origin. There are no goldcrests on Madeira, where the Madeira firecrest is the only Regulus species.The Canary Islands were colonised in two waves. The first step was the occupation of Tenerife and La Gomera 1.9–2.3 million years ago, followed by a separate invasion of El Hierro and La Palma 1.3–1.8 mya.
Birds from the Canary Islands are particularly distinctive having a black forehead, pink-buff underparts and a darker closed wing, and have been sometimes treated either as a subspecies of the common firecrest or as a different Regulus species altogether. They were sometimes called the Tenerife goldcrest, no matter which of the islands they lived on; however, a 2006 study of the vocalisations of these birds indicate that they actually comprise two subspecies of the goldcrest that are separable on voice; R. r. teneriffae occurring on Tenerife and the newly described subspecies, R. r. ellenthalerae, the western Canary Islands goldcrest, occurring on the smaller islands of La Palma and El Hierro. 
Tenerife goldcrest R. r. teneriffae (Seebohm, 1883). Found only on Tenerife, Canary Islands; it is a distinctive, small subspecies with a black forehead and pink-buff underparts.
Western Canary Islands goldcrest R. r. ellenthalerae (Päckert et al., 2006). Resident on La Palma and El Hierro, Canary Islands.Differences in songs, genetics and morphology suggests that the Azores were colonised in a single invasion in the late Pleistocene, about 100,000 years ago. It is likely that the initial colonisation was of the easternmost islands, with a subsequent spread to the central and western island groups from the western caldera of São Miguel, where both eastern and western song types are found.

Output: What two groups of goldcrest taxa are found on the Atlantic Islands of Macaronesia?


Input: Consider Input: Passage: The modern interest in the Hoysalas is due to their patronage of art and architecture rather than their military conquests. The brisk temple building throughout the kingdom was accomplished despite constant threats from the Pandyas to the south and the Seunas Yadavas to the north. Their architectural style, an offshoot of the Western Chalukya style, shows distinct Dravidian influences. The Hoysala architecture style is described as Karnata Dravida as distinguished from the traditional Dravida, and is considered an independent architectural tradition with many unique features.A feature of Hoysala temple architecture is its attention to exquisite detail and skilled craftsmanship. The tower over the temple shrine  (vimana) is delicately finished with intricate carvings, showing attention to the ornate and elaborately detailed rather than to a tower form and height. The stellate design of the base of the shrine with its rhythmic projections and recesses is carried through the tower in an orderly succession of decorated tiers. Hoysala temple sculpture replicates this emphasis on delicacy and craftsmanship in its focus on depicting feminine beauty, grace and physique. The Hoysala artists achieved this with the use of Soapstone (Chloritic schist), a soft stone as basic building and sculptural material.The Chennakesava Temple at Belur (1117), the Hoysaleswara temple at Halebidu (1121), the Chennakesava Temple at Somanathapura (1279), the temples at Arasikere (1220), Amruthapura (1196), Belavadi (1200), Nuggehalli (1246), Hosaholalu (1250), Aralaguppe (1250), Korvangla (1173), Haranhalli (1235), Mosale and Basaralu (1234)  are some of the notable examples of Hoysala art. While the temples at Belur and Halebidu are the best known because of the beauty of their sculptures, the Hoysala art finds more complete expression in the smaller and lesser known temples. The outer walls of all these temples contain an intricate array of stone sculptures and horizontal friezes (decorative mouldings) that depict the Hindu epics. These depictions are generally clockwise in the traditional direction of circumambulation (pradakshina). The temple of Halebidu has been described as an outstanding example of Hindu architecture and an important milestone in Indian architecture. The temples of Belur and Halebidu are a proposed UNESCO world heritage sites.

Output: What organization are the temples with known for their sculptures proposed to be world heritage sites?


Input: Consider Input: Passage: There are more than 20 major dams on the Willamette's tributaries, as well as a complex series of levees, dikes, and channels to control the river's flow.
The only dam on the Willamette's main stem is the Willamette Falls Dam, a low weir-type structure at Willamette Falls that diverts water into the headraces of the adjacent mills and a power plant.  The locks at Willamette Falls were completed in 1873.  Elsewhere on the main stem, numerous minor flow-regulation structures force the river into a narrower and deeper channel to facilitate navigation and flood control.The dams on the Willamette's major tributaries are primarily large flood-control, water storage, and power-generating dams. Thirteen of these dams were built from the 1940s through the 1960s to be operated by the United States Army Corps of Engineers (USACE), and 11 of those produce hydropower. Flood-control dams operated by the USACE are estimated to hold up to 27 percent of the Willamette's runoff. They are used to regulate river flows so as to cut peaks off floods and increase low flows in late summer and autumn, and to divert water into deeper, narrower channels to prevent flooding. In addition, a relatively small of amount of the water stored in the reservoirs is used for irrigation.
Detroit Dam on the North Santiam River is the second tallest dam in the Willamette River basin after Cougar Dam. It is 463 feet (141 m) high and stores 455,000 acre feet (561,000,000 m3) of water. Lookout Point Dam on the Middle Fork Willamette River, forming Lookout Point Lake, has the largest water storage capacity, at 477,700 acre feet (589,200,000 m3). The other 11 dams are Big Cliff on the North Santiam River; Green Peter and Foster on the Santiam River; Cougar on the South Fork McKenzie River;  Blue River on the Blue River; Fern Ridge on the Long Tom River; Hills Creek, Dexter on the Middle Fork Willamette River; Fall Creek on Fall Creek; Cottage Grove on the Coast Fork Willamette River, and Dorena on the Row River.A continuing controversy about these high dams involves Chinook salmon and steelhead blocked from roughly half of their historic habitat and spawning grounds on the Willamette's major tributaries. Unable to survive and reproduce as they once did, they have been "brought to the brink of extinction".  Endangered species listings and a subsequent lawsuit by Willamette Riverkeeper led to a plan to improve fish passage and other actions to help native fish recover in 2008. Since then, work has proceeded slowly, and the Corps, citing engineering difficulties and cost, may not meet the original agreed-upon deadline of 2023 for a system of effective remedies.Other major dams in the Willamette watershed are owned by other interests; for example, several hydroelectric facilities on the Clackamas River are owned by Portland General Electric. They include the River Mill Hydroelectric Project, the Oak Grove project, and the dam at Timothy Lake.
Output: What structures are used to produce hydropower?
