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

Example Input: Passage: Curiously, it appears that the Greeks did not "breed" their slaves, at least during the Classical Era, though the proportion of houseborn slaves appears to have been rather large in Ptolemaic Egypt and in manumission inscriptions at Delphi. Sometimes the cause of this was natural; mines, for instance, were exclusively a male domain. On the other hand, there were many female domestic slaves. The example of African slaves in the American South on the other hand demonstrates that slave populations can multiply.Xenophon advised that male and female slaves should be lodged separately, that "…nor children born and bred by our domestics without our knowledge and consent—no unimportant matter, since, if the act of rearing children tends to make good servants still more loyally disposed, cohabiting but sharpens ingenuity for mischief in the bad." The explanation is perhaps economic; even a skilled slave was cheap, so it may have been cheaper to purchase a slave than to raise one. Additionally, childbirth placed the slave-mother's life at risk, and the baby was not guaranteed to survive to adulthood.Houseborn slaves (oikogeneis) often constituted a privileged class. They were, for example, entrusted to take the children to school; they were "pedagogues" in the first sense of the term. Some of them were the offspring of the master of the house, but in most cities, notably Athens, a child inherited the status of its mother.
Example Output: What were entrusted to take children to school?

Example Input: Passage: Cole Trickle is a young racer from Eagle Rock, California, with years of experience in open-wheel racing, winning championships in the United States Auto Club. Originally setting his sights on the Indianapolis 500, Cole realizes that "To win in Indy I'd need a great car, but stock cars are all the same". He is recruited by Chevrolet dealership tycoon Tim Daland to race for his team in the NASCAR Winston Cup Series. Daland brings former crew chief and car builder Harry Hogge out of retirement to lead Cole's pit crew. After Cole sets a fast time in a private test at Charlotte Motor Speedway, Hogge builds him a new Chevrolet Lumina.
In his first few races, Cole has difficulty adjusting to the larger NASCAR stock cars and communicating with his crew, while being intimidated on the track by Winston Cup Champion and dirty driver Rowdy Burns; these obstacles, combined with crashes and blown engines, prevent Cole from finishing the races. Discovering that Cole does not understand common NASCAR terminology, Harry puts him through rigorous training. This pays off at the Darlington race, when Cole uses a slingshot maneuver from the outside line to overtake Rowdy and win his first race.
The rivalry between Cole and Rowdy intensifies throughout the season until the Firecracker 400 in Daytona, where both drivers are seriously injured after being caught in "The Big One". Recovering in Daytona Beach, Cole develops a romantic relationship with Dr. Claire Lewicki, a neurosurgeon at Halifax Hospital. NASCAR President Big John brings Rowdy and Cole together in a meeting and warns them that he and his sport will no longer tolerate any hanky-panky from the two rivals. Persuaded by Big John, Cole and Rowdy have lunch and settle their differences by banging rental cars on the beach. The bitter rivals soon become close friends.
Example Output:
What is the first name of the person who is recruited by a Chevrolet dealership tycoon?
