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.

Example Input: 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 thereand by being the tallest American building built since the 1974 completion of Sears (now Willis) TowerTrump confounds those who predicted after 9/11 that iconic skyscrapers would never be built again. At the same time, Trump's heightoriginally pegged at more than 2,000 feet but eventually scaled back to 1,362 feetsuggests that the fear spawned by the attacks did have some effect.
Example Output: What is the final height in feet of the building that was ranked in 2010 as having one of the best spas?

Example Input: Passage: Rebuilding was rapid and performed on a grand scale. Rejecting calls to completely remake the street grid, San Franciscans opted for speed. Amadeo Giannini's Bank of Italy, later to become Bank of America, provided loans for many of those whose livelihoods had been devastated. The influential San Francisco Planning and Urban Research Association or SPUR was founded in 1910 to address the quality of housing after the earthquake. The earthquake hastened development of western neighborhoods that survived the fire, including Pacific Heights, where many of the city's wealthy rebuilt their homes. In turn, the destroyed mansions of Nob Hill became grand hotels. City Hall rose again in splendid Beaux Arts style, and the city celebrated its rebirth at the Panama-Pacific International Exposition in 1915.It was during this period San Francisco built some of its most important infrastructure. Civil Engineer Michael O'Shaughnessy was hired by San Francisco Mayor James Rolph as chief engineer for the city in September 1912 to supervise the construction of the Twin Peaks Reservoir, the Stockton Street Tunnel, the Twin Peaks Tunnel, the San Francisco Municipal Railway, the Auxiliary Water Supply System, and new sewers. San Francisco's streetcar system, of which the J, K, L, M, and N lines survive today, was pushed to completion by O'Shaughnessy between 1915 and 1927. It was the O'Shaughnessy Dam, Hetch Hetchy Reservoir, and Hetch Hetchy Aqueduct that would have the largest effect on San Francisco. An abundant water supply enabled San Francisco to develop into the city it has become today.
In ensuing years, the city solidified its standing as a financial capital; in the wake of the 1929 stock market crash, not a single San Francisco-based bank failed. Indeed, it was at the height of the Great Depression that San Francisco undertook two great civil engineering projects, simultaneously constructing the San FranciscoOakland Bay Bridge and the Golden Gate Bridge, completing them in 1936 and 1937, respectively. It was in this period that the island of Alcatraz, a former military stockade, began its service as a federal maximum security prison, housing notorious inmates such as Al Capone, and Robert Franklin Stroud, the Birdman of Alcatraz. San Francisco later celebrated its regained grandeur with a World's fair, the Golden Gate International Exposition in 193940, creating Treasure Island in the middle of the bay to house it.
Example Output: What is the name of the city that celebrated its rebirth at the Panama-Pacific International Exposition in 1915?

Example Input: Passage: Chaco Canyon lies at the geographic center of the San Juan Basin. It is located in northwestern New Mexico 60 miles (97 km) north of Interstate 40 and 130 miles (210 km) from Gallup, the nearest city. The continental divide is 20 miles (32 km) east. Chaco Canyon was created by the Chaco River, which cut several hundred feet into Chacra Mesa. The elevation of the sandstone canyon and the surrounding high-desert terrain is approximately 6,000 feet (1,800 m). Though most of the Chacoan sites are located at the bottom of the canyon, the group also includes some ruins not in the canyon proper, extending 35 miles (56 km) from Kin Ya'a in the south to Pueblo Alto in the north, and 20 miles (32 km) from Pueblo Pintado to the northeast and Penasco Blanco in the southwest. In terms of water drainage and cultural affinity, the area is part of the San Juan Basin, which includes Mesa Verde in Colorado and Kayenta, Arizona.Chetro Ketl lies 0.4 miles (0.64 km) east of Pueblo Bonito, in an area that archeologists call downtown Chaco. Scholars theorize that the area may be an ancestral sacred zone demarcated by a low masonry wall that encloses Chetro Ketl, Pueblo Bonito, and Pueblo del Arroyo. Chetro Ketl's position is symmetrical to Pueblo Bonito; the buildings are equidistant from a north-south axis that runs across the canyon. Anna Sofaer proposed that many of the great houses in Chaco Canyon were constructed to emphasize astronomical alignments; during the minor lunar standstill, the full moon rises along Chetro Ketl's back wall.Chetro Ketl is located opposite a large opening in the canyon known as South Gap, which helped maximize the building's exposure to the sun while increasing visibility and access to the south. Its rear wall runs parallel to the canyon, and at less than 100 feet (30 m) from the cliffs its proximity allowed inhabitants to benefit from passive solar energy emanating from the rocks. Chetro Ketl is not perfectly aligned to the cardinal directions, but its nominal southerly orientation further enhanced solar exposure to its tiered rooms.
Example Output:
What elevation and the surrounding high-desert terrain is approximately 6,000 feet?
