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 Q]: Passage: Dr Stedman is murdered by an intruder in his study and two toy soldiers are stolen from his desk. The next day, Hugh Drummond reads about the murder in the newspaper. He is approached by a friend, Phillip Coleman, who tells him that he owns two similar figures and that he has received first offers, then threats to sell them. According to Coleman, the soldiers are 900 years old, dating back to the time of William the Conqueror. Coleman leaves the two painted lead figures with Drummond for safety and asks him to look into the affair. To flush out whoever is trying to get the figurines they plant a press story that Drummond has bought them from Coleman.
When a woman, who introduces herself as journalist Estelle Gorday, visits Drummond's apartment, she recognizes the right figures out of a collection that Drummond has assembled on his mantle piece. Drummond and his friend Longworth then visit Stedman Manor and meet the daughter of the victim, Cynthia. She tells them that her father's figures were very similar to those brought by Drummond but different in detail and that they were part of a set of 13 soldiers that Dr Stedman bought at auction together with an Anglo-Saxon palimpsest. He was translating that when he was killed and the scroll was also taken. Dr Stedman was convinced that the statues were exceedingly valuable and he received an offer to buy them from a man called Vane. Vane offered a multiple of what Stedman has paid and left very angry when rejected.
Drummond and Longworth follow an invitation by Ms Gorday. While they are there, Vane breaks into Drummond's apartment and steals the two soldiers. Coleman and Seymour, another friend of Drummond's, shadow him to a Soho flat. Seymour fetches Drummond and they return to Soho. Drummond and Longworth go up. A knife is thrown at them and they find Vane dead and the soldiers missing.
[EX A]: Who was translating a scroll?

[EX Q]: 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 A]: What two groups of goldcrest taxa are found on the Atlantic Islands of Macaronesia?

[EX Q]: Passage: Throughout most of its history, Istanbul has ranked among the largest cities in the world. By 500 CE, Constantinople had somewhere between 400,000 and 500,000 people, edging out its predecessor, Rome, for world's largest city. Constantinople jostled with other major historical cities, such as Baghdad, Chang'an, Kaifeng and Merv for the position of world's most populous city until the 12th century. It never returned to being the world's largest, but remained Europe's largest city from 1500 to 1750, when it was surpassed by London.The Turkish Statistical Institute estimates that the population of Istanbul Metropolitan Municipality was 14,377,019 at the end of 2014, hosting 19 percent of the country's population. Then about 97–98% of the inhabitants of the metropolitan municipality were within city limits, up from 89% in 2007 and 61% in 1980. 64.9% of the residents live on the European side and 35.1% on the Asian side. While the city ranks as the world's 5th-largest city proper, it drops to the 24th place as an urban area and to the 18th place as a metro area because the city limits are roughly equivalent to the agglomeration. Today, it forms one of the largest urban agglomerations in Europe, alongside Moscow. The city's annual population growth of 3.45 percent ranks as the highest among the seventy-eight largest metropolises in the Organisation for Economic Co-operation and Development. The high population growth mirrors an urbanization trend across the country, as the second and third fastest-growing OECD metropolises are the Turkish cities of İzmir and Ankara.
Istanbul experienced especially rapid growth during the second half of the 20th century, with its population increasing tenfold between 1950 and 2000. This growth in population comes, in part, from an expansion of city limits—particularly between 1980 and 1985, when the number of Istanbulites nearly doubled. The remarkable growth was, and still is, largely fueled by migrants from eastern Turkey seeking employment and improved living conditions. The number of residents of Istanbul originating from seven northern and eastern provinces is greater than the populations of their entire respective provinces; Sivas and Kastamonu each account for more than half a million residents of Istanbul. Istanbul's foreign population, by comparison, is very small, 42,228 residents in 2007. Only 28 percent of the city's residents are originally from Istanbul. The most densely populated areas tend to lie to the northwest, west, and southwest of the city center, on the European side; the most densely populated district on the Asian side is Üsküdar.
[EX A]:
Where are the migrants coming from that fuel the growth of the city that is number one in OCED growth?
