TASK DEFINITION: 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.
PROBLEM: 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 (5–10 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 Ruiz–Tolima 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.

SOLUTION: What partially collapsed, forming large (5–10 km wide) calderas?

PROBLEM: Passage: As of the 2010 U.S. census, the racial composition was as follows:
White: 63.8%
Black or African American: 18.6%
American Indian: 2.0%
Asian: 5.6% (1.9% Hmong, 0.9% Chinese, 0.7% Indian, 0.6% Korean, 0.4% Vietnamese, 0.3% Thai, 0.3% Laotian, 0.2% Filipino, 0.1% Japanese, 0.2% Other Asian)
Native Hawaiian/Pacific Islander: 0.1%
Other: 5.6%
Multiracial: 4.4%
Hispanic or Latino (of any race): 10.5% (7.0% Mexican, 1.3% Ecuadorian, 0.4% Puerto Rican, 0.3% Guatemalan, 0.2% Salvadoran, 1.3% Other Latino)White Americans make up about three-fifths of Minneapolis's population. This community is predominantly of German and Scandinavian descent. There are 82,870 German Americans in the city, making up over one-fifth (23.1%) of the population. The Scandinavian-American population is primarily Norwegian and Swedish. There are 39,103 Norwegian Americans, making up 10.9% of the population; there are 30,349 Swedish Americans, making up 8.5% of the city's population. Danish Americans are not nearly as numerous; there are 4,434 Danish Americans, making up only 1.3% of the population. Norwegian, Swedish, and Danish Americans together make up 20.7% of the population. This means that ethnic Germans and Scandinavians together make up 43.8% of Minneapolis's population, and make up the majority of Minneapolis's non-Hispanic white population. Other significant European groups in the city include those of Irish (11.3%), English (7.0%), Polish (3.9%), French (3.5%) and Italian (2.3%) descent. African Americans make up 18.6% of the city's population, with a large fraction hailing from Rust Belt cities such as Chicago and Gary, Indiana over the past three decades.
There are 10,711 individuals who identify as multiracial in Minneapolis: People of black and white ancestry number at 3,551, and make up 1.0% of the population. People of white and Native American ancestry number at 2,319, and make up 0.6% of the population. Those of white and Asian ancestry number at 1,871, and make up 0.5% of the population. Lastly, people of black and Native American ancestry number at 885, and make up 0.2% of Minneapolis's population.

SOLUTION: As of 2010, what percentage of people in Minneapolis were American Indian?

PROBLEM: Passage: In the early 19th century, medievalism, Romanticism, and the Gothic Revival reawakened interest in Arthur and the medieval romances. A new code of ethics for 19th-century gentlemen was shaped around the chivalric ideals embodied in the "Arthur of romance". This renewed interest first made itself felt in 1816, when Malory's Le Morte d'Arthur was reprinted for the first time since 1634. Initially, the medieval Arthurian legends were of particular interest to poets, inspiring, for example, William Wordsworth to write "The Egyptian Maid" (1835), an allegory of the Holy Grail. Pre-eminent among these was Alfred Tennyson, whose first Arthurian poem "The Lady of Shalott" was published in 1832. Arthur himself played a minor role in some of these works, following in the medieval romance tradition. Tennyson's Arthurian work reached its peak of popularity with Idylls of the King, however, which reworked the entire narrative of Arthur's life for the Victorian era. It was first published in 1859 and sold 10,000 copies within the first week. In the Idylls, Arthur became a symbol of ideal manhood who ultimately failed, through human weakness, to establish a perfect kingdom on earth. Tennyson's works prompted a large number of imitators, generated considerable public interest in the legends of Arthur and the character himself, and brought Malory's tales to a wider audience. Indeed, the first modernisation of Malory's great compilation of Arthur's tales was published in 1862, shortly after Idylls appeared, and there were six further editions and five competitors before the century ended.

SOLUTION:
What is the first name of the person whose Arthurian work reached its peak of popularity with Idylls of the King?
