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.

Passage: Two groups of goldcrest taxa are found on the Atlantic islands of Macaronesia. Birds on the Canary Islands are ancient colonists, whereas those on The Azores are of more recent origin. There are no goldcrests on Madeira, where the Madeira firecrest is the only Regulus species.The Canary Islands were colonised in two waves. The first step was the occupation of Tenerife and La Gomera 1.9–2.3 million years ago, followed by a separate invasion of El Hierro and La Palma 1.3–1.8 mya.
Birds from the Canary Islands are particularly distinctive having a black forehead, pink-buff underparts and a darker closed wing, and have been sometimes treated either as a subspecies of the common firecrest or as a different Regulus species altogether. They were sometimes called the Tenerife goldcrest, no matter which of the islands they lived on; however, a 2006 study of the vocalisations of these birds indicate that they actually comprise two subspecies of the goldcrest that are separable on voice; R. r. teneriffae occurring on Tenerife and the newly described subspecies, R. r. ellenthalerae, the western Canary Islands goldcrest, occurring on the smaller islands of La Palma and El Hierro. 
Tenerife goldcrest R. r. teneriffae (Seebohm, 1883). Found only on Tenerife, Canary Islands; it is a distinctive, small subspecies with a black forehead and pink-buff underparts.
Western Canary Islands goldcrest R. r. ellenthalerae (Päckert et al., 2006). Resident on La Palma and El Hierro, Canary Islands.Differences in songs, genetics and morphology suggests that the Azores were colonised in a single invasion in the late Pleistocene, about 100,000 years ago. It is likely that the initial colonisation was of the easternmost islands, with a subsequent spread to the central and western island groups from the western caldera of São Miguel, where both eastern and western song types are found.

Ex Output:
What two groups of goldcrest taxa are found on the Atlantic Islands of Macaronesia?

Passage: After the Wicked Witch of the West is melted by a bucket of water, and Dorothy is sent back to her world, Glinda, the Good Witch of the South, decides to revive the Wicked Witch and remove her powers by storing them in a magic broom. Glinda then gives the magical broom to Dorothy's friends, Tin Woodman, Cowardly Lion, and Scarecrow, and they become the guardians of the broom.
Evilene, the Wicked Witch, conspires with her Flying Monkeys to retrieve her broom. However, a friendly little monkey named Ozzy forgets to close the gate of the castle and a battle ensues between the flying monkeys and the 'Bums of Oz.' Evilene retrieves her broom and repels the Champions of Oz from the castle. She then punishes Ozzy's father, transforming him into a chicken. Angered by the witch's spell on his father, Ozzy steals the broom from Evilene and runs away from the palace.
Ozzy reaches Glinda to find she has been paralyzed by accidentally drinking a magic potion created by her niece Gabby, who is unable to create an antidote without a vital ingredient based on wood. Gabby and Ozzy set off to find the Champions of Oz. They are pursued by the other Flying Monkeys.
They soon find Cowardly Lion, who is out of sorts due to the witch's spell, but with some effort they guide him to the north town, where they find the Tin Woodman, who is extremely depressed by the spell. The spell-raged Lion smashes the Tin Man to bits, but calms down when Ozzy accidentally hits him with the magic broom.
Ozzy, Gaby, and the Cowardly Lion take the Tin Man's parts to the Library of Oz where (due to the spell) Scarecrow is obsessively reading books in an effort to become more intelligent. He quickly repairs Tin with the help from a clue. However, the group is attacked by the Flying Monkeys, and in the chaos Ozzy cures Scarecrow of the spell's effects, but they are unable to save Gabby from being whisked away by the Flying Monkeys.

Ex Output:
What are the names of the people who are pursued by Flying Monkeys?

Passage: The paddle steamer SS Arctic, owned by the Collins Line of New York, sank on September 27, 1854 after a collision with SS Vesta, a much smaller vessel, 50 miles (80 km) off the coast of Newfoundland.  Passenger and crew lists indicate that there were probably more than 400 on board; of these, only 88 survived, most of whom were members of the crew.  All the women and children on board perished.
Arctic was the largest and most celebrated of the four Collins steamers that had operated a regular transatlantic passenger and mail carrying service since 1850. After the collision, Arctic's captain, James Luce, first attempted to assist the stricken Vesta, which he believed was in imminent danger of sinking. When he discovered that his own ship had been seriously holed below the waterline, he decided to run her towards the nearest land, in the hopes of reaching safety. His plan failed; the engines stopped when the ship was still a considerable distance from land. Arctic's lifeboat capacity was sufficient for less than half of those on board; when Luce ordered these launched, a breakdown in order and discipline meant that most places in the boats were taken by members of the crew or the more able-bodied male passengers. The rest struggled to build makeshift rafts, but most were unable to leave the ship, and went down with her when she sank, four hours after the collision.  Vesta, which initially appeared to have sustained mortal damage, was kept afloat by her watertight bulkheads, and managed to limp into harbor at St. John's, Newfoundland.
Two of the six lifeboats that left Arctic reached the Newfoundland shore safely, and another was picked up by a passing steamer, which also rescued a few survivors from improvised rafts.  Among those saved was Captain Luce, who had regained the surface after initially going down with the ship. The other three lifeboats disappeared without a trace. The limited telegraph facilities of the time meant that news of Arctic's loss did not reach New York until two weeks after the sinking. Initial public sorrow at the ship's loss quickly turned to anger at the perceived cowardice of the crew. Despite press calls for a full investigation into the disaster, none took place, and nobody was held legally responsible. Demands for the introduction of further safety measures on passenger-carrying vessels were likewise sidestepped.  Luce, who was generally exonerated from blame by the public, retired from the sea; some of the surviving crew chose not to return to the U.S. The Collins Line continued its transatlantic service, until further maritime losses and insolvency led to its closure in 1858.

Ex Output:
What is the name of the boat that had probably more than 400 on board when is sank?
