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.

Q: Passage: There are two major valleys in the park, Death Valley and Panamint Valley. Both of these valleys were formed within the last few million years and both are bounded by north–south-trending mountain ranges. These and adjacent valleys follow the general trend of Basin and Range topography with one modification: there are parallel strike-slip faults that perpendicularly bound the central extent of Death Valley. The result of this shearing action is additional extension in the central part of Death Valley which causes a slight widening and more subsidence there.
Uplift of surrounding mountain ranges and subsidence of the valley floor are both occurring. The uplift on the Black Mountains is so fast that the alluvial fans (fan-shaped deposits at the mouth of canyons) there are small and steep compared to the huge alluvial fans coming off the Panamint Range. Fast uplift of a mountain range in an arid environment often does not allow its canyons enough time to cut a classic V-shape all the way down to the stream bed. Instead, a V-shape ends at a slot canyon halfway down, forming a 'wine glass canyon.'  Sediment is deposited on a small and steep alluvial fan.
At 282 feet (86 m) below sea level at its lowest point, Badwater Basin on Death Valley's floor is the second-lowest depression in the Western Hemisphere (behind Laguna del Carbón in Argentina), while Mount Whitney, only 85 miles (137 km) to the west, rises to 14,505 feet (4,421 m). This topographic relief is the greatest elevation gradient in the contiguous United States and is the terminus point of the Great Basin's southwestern drainage. Although the extreme lack of water in the Great Basin makes this distinction of little current practical use, it does mean that in wetter times the lake that once filled Death Valley (Lake Manly) was the last stop for water flowing in the region, meaning the water there was saturated in dissolved materials. Thus the salt pans in Death Valley are among the largest in the world and are rich in minerals, such as borax and various salts and hydrates. The largest salt pan in the park extends 40 miles (64 km) from the Ashford Mill Site to the Salt Creek Hills, covering some 200 square miles (520 km2) of the valley floor. The best known playa in the park is the Racetrack, known for its moving rocks.

A: What is the lowest point of Death Valley?

Q: Passage: The company, retaining the title "Sadler's Wells Opera", opened at the Coliseum on 21 August 1968, with a new production of Mozart's Don Giovanni, directed by Sir John Gielgud. Though this production was not well received, the company rapidly established itself with a succession of highly praised productions of other works. Arlen died in January 1972, and was succeeded as managing director by Lord Harewood.The success of the 1968 Mastersingers was followed in the 1970s by the company's first Ring cycle, conducted by Goodall, with a new translation by Andrew Porter and designs by Ralph Koltai.  The cast included Norman Bailey, Rita Hunter and Alberto Remedios. In Harewood's view, among the highlights of the first ten years at the Coliseum were the Ring, Prokofiev's War and Peace, and Richard Strauss's Salome and Der Rosenkavalier.
The company's musical director from 1970 to 1977 was Charles Mackerras. Harewood praised his exceptional versatility, with a range "from The House of the Dead to Patience." Among the operas he conducted for the company were Handel's Julius Caesar starring Janet Baker and Valerie Masterson; five Janáček operas; The Marriage of Figaro with pioneering use of 18th century performing style; Massenet's Werther; Donizetti's Mary Stuart with Baker; and Sullivan's Patience. The company took the production of the last to the Vienna Festival in 1975, along with Britten's Gloriana. Sir Charles Groves succeeded Mackerras as musical director from 1978 to 1979, but Groves was unwell and unhappy during his brief tenure. Starting in 1979, Mark Elder succeeded Groves in the post, and described Groves "immensely encouraging and supportive".A long-standing concern of Arlen and then Harewood was the need to change the company's name to reflect the fact that it was no longer based at Sadler's Wells theatre. Byam Shaw commented "The one major setback the Sadler's Wells Opera Company suffered from its transplant was that unheeding taxi drivers kept on taking their patrons up to Rosebery Avenue".Harewood considered it an elementary rule that "you must not carry the name of one theatre if you are playing in another one." Covent Garden, protective of its status, objected to the suggestion that the Sadler's Wells company should be called "The British National Opera" or "The National Opera", although neither Scottish Opera nor the Welsh National Opera opposed such a change. Eventually the British government decided the matter, and the title "English National Opera" was approved. The company's board adopted the new name in November 1974. In 1977, in response to demand for more opera productions in English provincial cities, a second company was established. It was based at Leeds in northern England, and was known as ENO North. Under Harewood's guidance, it flourished, and in 1981 it became an independent company, Opera North.

A: What name did the company that was  titled "Sadler's Wells Opera" eventually change its name to?

Q: Passage: Fodor's Chicago 2010 ranks the hotel as having one of the best spas and one of the best pools in the city. It also ranked the hotel as a Fodor's Choice among Chicago lodging options.  Fodor's also notes that the hotel has impeccable service and lavish amenities, but also notes that the hotel may be a bit "too decadent", with offerings such as $25 bottles of water.Frommer's Chicago 2010 describes the hotel as having the gorgeous views and upscale amenities to provide a place to go to live the life of a wealthy tourist. The building is praised for its location, which provides as many views along the Chicago River as possible. Its modern architecture is praised for "contemporary synthesis of adjacent building fabrics and modulations" that preserve the city's architectural heritage and integrate the riverfront setting.BlackBook Magazine's Guide to Chicago describes the Hotel as an embodiment of poshness which gives the visitor bragging rights upon his/her return home.Forbes Travel Guide describes the hotel as having an understated upscale lobby, sophisticated lounge, gorgeous restaurant and lavish rooms with amazing views.  It also describes the hotel as befitting of the Trump name in several ways.Time Out describes the building as a "testament to a vibrant 21st-century optimism in Chicago". It notes that the hotel meets all expectations attached to the name Trump in terms of luxury, modern conveniences and speaks highly of the views.Insight Guides describes the building's architectural swagger as fitting for the post-September 11 attacks skyline. Ten years after the September 11 attacks, Kamin described the building as the one that "best reveals how the Sept. 11 terrorist attacks either did or did not change architecture". Kamin clarified his belief:
Simply by virtue of standing there—and by being the tallest American building built since the 1974 completion of Sears (now Willis) Tower—Trump confounds those who predicted after 9/11 that iconic skyscrapers would never be built again. At the same time, Trump's height—originally pegged at more than 2,000 feet but eventually scaled back to 1,362 feet—suggests that the fear spawned by the attacks did have some effect.

A:
What is the final height in feet of the building that was ranked in 2010 as having one of the best spas?
