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.

Ex 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.

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

Passage: Matt Brady comes home from World War I to a city where his older brother Tim is a political kingpin. Matt meets an old friend, Bob Herrick, but an argument leads to a fistfight. He ends up late for a date with Elsie Reynolds, who is furious. Matt angrily replies that he wants nothing more to do with her.
Matt's self-destructive behavior continues at a restaurant, where he intervenes on behalf of a forlorn customer, Lorry Reed, punching a waiter. He not only takes sympathy on her, he impulsively insists they get married.
Regretting his actions the next day, Matt's temper again flares when Tim Brady decides to get the marriage annulled. Matt tells him to mind his own business. Minutes later, Tim dies of a heart attack.
Years go by. Matt, still in a loveless marriage with Lorry, has followed his brother into politics. His unethical methods include making money on a tip from gangster Johnny Mazia and claiming half the profits of a cement business in exchange for guaranteeing it city projects. Bob has married Elsie, meanwhile, and become Matt's lawyer and insurance commissioner.
Matt continues to mistreat Lorry, even giving her a very expensive necklace only to make Elsie envious. A newspaper editor and prosecutor begin investigating Matt, whose net worth also vanishes with the stock market's crash. He goes into business with gangster Johnny, inadvertently becoming an accomplice in a killing spree.
An effort to make things right leads to a fight resulting in Johnny's death, but Matt is indicted and shocked when Bob testifies against him. Lorry leaves, telling Matt how he deluded himself that he had even one friend. Matt ends up by himself, behind bars.

Ex Output:
What is the first name of the brother of the political kingpin?

Passage: Although The Big Cypress is the largest growth of cypress swamps in South Florida, such swampsas well as portions of sawgrass marshescan be found near the Atlantic Coastal Ridge and between Lake Okeechobee and the Eastern flatwoods. Hardwood hammocks and pineland are often interspersed with the cypress ecosystem. Much like tree islands that are colloquially referred to as "heads", cypress trees grow in formations that resemble domes, with the tallest and thickest trunks in the center, rooted in the deepest peat. As the peat thins out, cypresses continue to grow, but are smaller and thinner, giving the small forest the appearance of a dome. They also grow in strands, slightly elevated on a plateau of limestone and surrounded on two sides by sloughs. Other hardwood trees can be found in cypress domes, such as red maple (Acer rubrum), swamp bay (Persea palustris), and pop ash (Fraxinus caroliniana). If cypresses are removed, hardwoods take over, and the ecosystem is recategorized as a mixed swamp forest.
Because the cypress domes and strands retain moisture and block out much of the sunlight, plants such as orchids, bromeliads, and ferns thrive in cypress domes and strands. Orchids bloom throughout the year in cypress heads, and bromeliads appear in many varieties; on Fakahatchee Strand alone, thirteen species have been documented. Bromeliads collect moisture from rain and humidity in the bases of their leaves, which also nurture frogs, lizards and various insects. Wood storks (Mycteria americana) nest almost exclusively in cypress forests and in the past 100 years have seen a dramatic decline, probably due to lack of reproduction tied to controlled water. Wood storks' reproductive cycles coincide with the dry season, when small fish and amphibians are trapped in shallow pools and puddles. When water from canals or locks is released too soon or not at all, storks are unable to find enough food for themselves and their offspring. An estimated 20,000 wood storks nested in The Big Cypress in the 1930s, but by the 1990s less than 2,000 were counted.

Ex Output:
What are the common names of the other hardwood trees that can be found in cypress domes?
