instruction:
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: As a result of the Berlin Conference of 1884-1885, the Congo Basin is claimed by King Leopold II of the Belgians, who rules the Congo Free State in personal union with the Kingdom of Belgium. The country is on the verge of bankruptcy, Leopold having borrowed huge sums of money to finance the construction of railways and other infrastructure projects. He sends his envoy Léon Rom to secure the fabled diamonds of Opar. Rom's expedition is ambushed and massacred. A tribal leader, Chief Mbonga, offers Rom the diamonds in exchange for an old enemy: Tarzan.
The man once called "Tarzan", John Clayton III, has left Africa behind and settled down in London with his American-born wife, Jane Porter. He took up his birth name and ancestral family residence as Lord Greystoke. In the eight years since returning from Africa, John's story as Tarzan has become legendary among the Victorian public, although John wants to leave that past behind. Through the British Prime Minister, John is invited by King Leopold to visit Boma and report on the development of the Congo by Belgium; he declines to participate in the perceived publicity stunt.
answer:
What is the first name of the person who sends his envoy to secure diamonds?

Passage: When Muggs refuses to train for the Golden Gloves match unless he has his own private camp in the country, Danny placates his pal by enlisting members of the Vassey Street Boys' Club in the Civilian Conservation Corps. Arriving at the camp, Muggs refuses to accept the authority of Allen, the leader of the boys, and treats the facility as if it was his own private property. Later, Muggs has a chance to demonstrate his true nature when he risks his own life to save Al from being crushed by a falling tree. The camp captain praises Muggs for his courage, and as a reward, Muggs requests a boxing match with Al. Norton, a small-time boxing promoter, comes to watch the fight, which ends in a draw. Furious at the outcome, Muggs refuses to shake his opponent's hand, an act which earns the enmity of the other boys. When the captain fails to remove the chip from Muggs' shoulder, his daughter, Elaine, tries to reform him through kindness. Meanwhile, Willie, one of the boys, steals one hundred dollars from the camp cash box and confides to Muggs that he needed the money for his poor aunt. To get the money back for Willie, Muggs has Norton arrange a fight, and although he takes a beating in the ring, Muggs earns the one hundred dollars. While returning the money to the cash box, Muggs is caught and accused of theft. He refuses to inform on Willie, though and instead runs away. Danny then forces the truth from Willie, thus proving Muggs' true sportsmanship.
answer:
Who arranges a private camp for Muggs?


question:
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.
answer:
Where are the migrants coming from that fuel the growth of the city that is number one in OCED growth?
