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: Phaedra is a poor Greek sponge diver on the island of Hydra. She works from the boat of her boyfriend, Rhif, an illegal immigrant from Albania. She accidentally finds an ancient Greek statue of a boy riding a dolphin on the bottom of the Aegean Sea. Her efforts to sell it to the highest bidder lead her to two competing individuals: Dr. James Calder, an honest archaeologist who will surrender it to Greek authorities, and Victor Parmalee, an aesthete and an unscrupulous dealer with a history of trying to acquire works of art stolen by the Nazis from their owners.
Calder and Parmalee each try to win Phaedra's cooperation. She works in concert with Parmalee, while developing feelings for Calder. When she seems to waver, Rhif decides to make the deal with Parmalee work. The film reaches a happy conclusion, with virtue rewarded, the statue celebrated by the people of Hydra, and Phaedra and Calder in each other's arms. Parmalee, a man with no apparent national loyalties or heritage, sets course for Monte Carlo.

Ex Output:
Who is dating an illegal immigrant?

Passage: Captain Crewe (played by Ian Hunter), called to fight in the Second Boer War, has to leave his daughter Sara with her pony at Miss Minchin's School for Girls. With all the money Captain Crewe can offer, Miss Minchin gives Sara a fancy, private room.
Although worried about her father, Sara is distracted by riding lessons. It is during these riding lessons that Sara helps contrive meetings between Miss Rose, her teacher, and Mr. Geoffrey, the riding instructor, who is also the grandson of the mean-spirited next door neighbor, Lord Wickham. Sara hears news that Mafeking is free and expects her father will soon come home. Miss Minchin throws Sara a lavish birthday party. During the party, Captain Crewe's solicitor arrives with the sad news that Captain Crewe has died and his real estate, the basis for his wealth, has been confiscated. Miss Minchin ends Sara's party abruptly. Without her father's financial support, Sara becomes a servant, now working at the school she used to attend. Sara gains new solace in a friendship with Ram Dass who lives next door.  She also receives support from Miss Minchin's brother, Hubert, who does not agree with her treatment. Miss Rose and Mr. Geoffrey are found out and fired. Geoffrey joins the military.

Ex Output:
Whose treatment does Hubert object to?

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.
