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: The first eruptions of Nevado del Ruiz occurred about 1.8 million years ago at the beginning of the Pleistocene epoch. Three primary eruption periods in the history of the massif have been identified: ancestral, older and present. During the ancestral period between one million to two million years ago, a complex of large stratovolcanoes was created. Between 1.0 million and 0.8 million years ago, they partially collapsed, forming large (510 km wide) calderas. During the older period, which lasted from 0.8 million to 0.2 million years ago, a new complex of large stratovolcanoes developed (including Older Ruiz, Tolima, Quindio, and Santa Isabel). Once again explosive summit calderas formed from 0.2 million to 0.15 million years ago.The present period began about 150,000 years ago and involved the development of the present volcanic edifice through the emplacement of lava domes made of andesite and dacite (igneous rocks) inside older calderas. During the past 11,000 years, Nevado del Ruiz passed through at least 12 eruption stages, which included multiple slope failures (rock avalanches), pyroclastic flows and lahars leading to partial destruction of the summit domes. During the past several thousand years, eruptions of the volcanoes in the RuizTolima massif have mostly been small, and the pyroclastic flow deposits have been much less voluminous than during the Pleistocene. Since the volcano's earlier eruptions are not recorded, volcanologists have used tephrochronology to date them.During recorded history, eruptions have consisted primarily of a central vent eruption (in the caldera) followed by an explosive eruption, then lahars. Ruiz's earliest identified Holocene eruption was about 6660 BC, and further eruptions occurred in 1245 BC 150 years (dated through radiocarbon dating), about 850 BC, 200 BC 100 years, 350 AD 300 years, 675 AD 50 years, in 1350, 1541 (perhaps), 1570, 1595, 1623, 1805, 1826, 1828 (perhaps),[b] 1829, 1831, 1833 (perhaps),[b] 1845, 1916, December 1984 March 1985, September 1985 July 1991, and possibly in April 1994.[b] Many of these eruptions involved a central vent eruption, a flank vent eruption, and a phreatic (steam) explosion. Ruiz is the second-most active volcano in Colombia after Galeras.

Output: What partially collapsed, forming large (510 km wide) calderas?

Input: Consider Input: Passage: During late 1930 and early 1931, the plans were revised and streamlined. March 1931 saw the announcement of Plan F-18, which called for an International Music Hall (now Radio City Music Hall) and its 31-story office building annex to occupy the northernmost of the three blocks, located between 50th and 51st streets. The 66-story 831-foot (253 m) RCA Building would be located on the central block's western half, between 49th and 50th streets, and would house RCA and NBC offices as well as broadcasting studios. The oval-shaped retail complex would occupy the block's eastern half, with a rooftop garden. A RKO-operated sound theater would be located in the southernmost block between 48th and 49th streets. In the center of Radio City would be a new three-block-long private street running between Fifth and Sixth avenues, with a concave plaza at the midpoint. The complex would also include space for a future Metropolitan Opera venue on the northernmost block. An underground pedestrian shopping mall, which would be located above the underground bus terminal, was also added in this plan. The complex would include 28,000 windows and more than 125,000 short tons (112,000 long tons) of structural steel, according to the builders. It would cost $250 million.For the first time, a scale rendering of the proposed complex was presented to the public. The rendering was much criticized, with some taking issue with details or general dimensions of the as-yet-unconfirmed proposal, and others lambasting the location of the tall skyscrapers around the plaza. Daniel Okrent writes that "almost everyone" hated the updated plans. The renowned architectural scholar Lewis Mumford went into exile in upstate New York specifically because the "weakly conceived, reckless, romantic chaos" of the plans for Rockefeller Center had violated his sense of style. Mumford's commentary provoked a wave of blunt, negative criticism from private citizens; newspapers, such as the New York Herald Tribune; and architects, including both Frank Lloyd Wright and Ralph Adams Cram, whose styles were diametrically opposed to each other. The New York Times took note of the "universal condemnation" of the proposal, and after the complex's architects changed their plans in response to the criticism, the Times stated, "It is cheering to learn that the architects and builders of Radio City have been stirred by the public criticism of their plans." Despite the controversy over the complex's design, Rockefeller retained the Associated Architects for his project.

Output: What is the full name of the person whose sense of style was violated by the "weakly conceived, reckless, romantic chaos" within the plans for Rockefeller Center?

Input: Consider Input: Passage: Plans for a new building began to take shape in 1872 when the state legislature appropriated $100,000 ($ 2.1 million as of 2019) towards a new capitol building. This second capitol, built between 1873 and 1876, was a two-story structure with an additional first level that was partly underground; the total cost was $325,000 ($ 7.6 million as of 2019). The cornerstone for the building was laid on October 5, 1873, during a ceremony that included a speech by Governor Stephen F. Chadwick and the music of several bands. Construction, on the same site as the 1855 building, was partly accomplished with convict labor from the Oregon State Penitentiary. Architects Justus F. Krumbein and W.G. Gilbert designed the building.Built of stone and five million bricks, Oregon's new capitol measured 275 by 136 feet (84 by 41 m) with a dome of 180 feet (55 m). The ground story was of native Oregon sandstone from the Umpqua region. The structure had a square rotunda on the interior that was 54 feet (16 m) tall. Also inside was a Senate chamber measuring 75 by 45 feet (23 by 14 m) and a House chamber of 85 by 75 feet (26 by 23 m). On the top floor was the Oregon Supreme Court with a courtroom measuring 54 by 45 feet (16 by 14 m) and the Oregon State Law Library, 75 by 70 feet (23 by 21 m). Also on the top floor was a viewing gallery for the House. On the exterior were ornamental pilasters and two-story porticos on the east and west ends. The building included a lunch counter. Additionally, the building had mullion-windowed wings. The large copper-clad dome was constructed with an iron and steel framework. This dome rose 54 feet (16 m) above the rest of the building and was 100 feet (30 m) tall. The building was of Renaissance style with Corinthian columns on the front entrance and was patterned after the United States Capitol. At that time, the capitol faced west toward the Willamette River. The government began using the building in August 1876, before the dome was built. Originally, plans called for towers on both sides of the dome (a tower on both ends of the building with the dome in the middle), but they were left out to save money. Oregon's second capitol building stood from 1876 to 1935.
Output: In what year did the government begin to use the capitol building that faced the Willamette River?
