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: From the moment the three were grounded on 14 July, Strindberg's highly specialized cartographic camera, which had been brought to map the region from the air, became instead a means of recording daily life in the icescape and the constant danger and drudgery of the trek. Strindberg took about 200 photos with his seven-kilogram (15 lb) camera over the course of the three months they spent on the pack ice, one of the most famous being his picture of Andree and Frnkel contemplating the fallen Eagle (see image above).Andree and Frnkel also kept meticulous records of their experiences and geographical positions, Andree in his "main diary," Frnkel in his meteorological journal. Strindberg's own stenographic diary was more personal in content, and included his general reflections on the expedition, as well as several messages to his fiancee Anna Charlier. All three manuscripts were eventually retrieved from the ice on Kvitya in 1930.
The Eagle had been stocked with safety equipment such as guns, snowshoes, sleds, skis, a tent, a small boat (in the form of a bundle of bent sticks, to be assembled and covered with balloon silk), most of it stored not in the basket but in the storage space arranged above the balloon ring. These items had not been put together with great care, or with any acknowledgment of adopting indigenous peoples' techniques for dealing with the extreme environment. In this, Andree contrasted not only with later but also with many earlier explorers.
Sven Lundstrom points to the agonizing extra efforts that became necessary for the team due to Andree's mistaken design of the sleds, with a rigid construction that borrowed nothing from the long proven Inuit sleds, and were so impractical for the difficult terrain. Andree called it "dreadful terrain", with channels separating the ice floes, high ridges, and partially iced-over melt ponds. The men's clothes included no furs but were woolen coats and trousers, plus oilskins. They wore the oilskins but the explorers reported always seeming to be damp or wet from the half-frozen pools of water on the ice and the typically foggy, humid Arctic summer air, and preoccupied with drying their clothes, mainly by wearing them. It would have meant certain death to lose the provisions lashed to one of the inconvenient sleds into one of the many channels that had to be laboriously crossed.
What is the name of the person whose fiancee was Anna Charlier?

Passage: In 1670, Charles II incorporated by royal charter the Hudson's Bay Company (HBC), granting it a monopoly on the fur trade in the area known as Rupert's Land, which would later form a large proportion of the Dominion of Canada. Forts and trading posts established by the HBC were frequently the subject of attacks by the French, who had established their own fur trading colony in adjacent New France.Two years later, the Royal African Company was inaugurated, receiving from King Charles a monopoly of the trade to supply slaves to the British colonies of the Caribbean. From the outset, slavery was the basis of the British Empire in the West Indies. Until the abolition of its slave trade in 1807, Britain was responsible for the transportation of 3.5 million African slaves to the Americas, a third of all slaves transported across the Atlantic. To facilitate this trade, forts were established on the coast of West Africa, such as James Island, Accra and Bunce Island. In the British Caribbean, the percentage of the population of African descent rose from 25% in 1650 to around 80% in 1780, and in the Thirteen Colonies from 10% to 40% over the same period (the majority in the southern colonies). For the slave traders, the trade was extremely profitable, and became a major economic mainstay for such western British cities as Bristol and Liverpool, which formed the third corner of the triangular trade with Africa and the Americas. For the transported, harsh and unhygienic conditions on the slaving ships and poor diets meant that the average mortality rate during the Middle Passage was one in seven.In 1695, the Parliament of Scotland granted a charter to the Company of Scotland, which established a settlement in 1698 on the Isthmus of Panama. Besieged by neighbouring Spanish colonists of New Granada, and afflicted by malaria, the colony was abandoned two years later. The Darien scheme was a financial disaster for Scotlanda quarter of Scottish capital was lost in the enterpriseand ended Scottish hopes of establishing its own overseas empire. The episode also had major political consequences, persuading the governments of both England and Scotland of the merits of a union of countries, rather than just crowns. This occurred in 1707 with the Treaty of Union, establishing the Kingdom of Great Britain.
In what year did the African population in the thirteen colonies contribute to 10%?

Passage: George Roger Waters (born 6 September 1943) is an English songwriter, singer, bassist, and composer. In 1965, he co-founded the progressive rock band Pink Floyd. Waters initially served solely as the bassist, but following the departure of songwriter Syd Barrett in 1968, he also became their lyricist, co-lead vocalist, and conceptual leader.
Pink Floyd achieved international success with the concept albums The Dark Side of the Moon (1973), Wish You Were Here (1975), Animals (1977), and The Wall (1979). By the early 1980s, they had become one of the most critically acclaimed and commercially successful groups in popular music; by 2013, they had sold more than 250 million albums worldwide. Amid creative differences, Waters left in 1985 and began a legal dispute with the remaining members over the use of the band's name and material. They settled out of court in 1987.
Waters' solo work includes the studio albums The Pros and Cons of Hitch Hiking (1984), Radio K.A.O.S. (1987), Amused to Death (1992), and Is This the Life We Really Want? (2017). In 2005, he released Ca Ira, an opera translated from Etienne and Nadine Roda-Gils' libretto about the French Revolution.
In 1990, Waters staged one of the largest rock concerts in history, The Wall Live in Berlin, with an attendance of 450,000. As a member of Pink Floyd, he was inducted into the U.S. Rock and Roll Hall of Fame in 1996 and the UK Music Hall of Fame in 2005. Later that year, he reunited with Pink Floyd bandmates Mason, Wright and David Gilmour for the Live 8 global awareness event, the group's first appearance with Waters since 1981. He has toured extensively as a solo act since 1999; he performed The Dark Side of the Moon in its entirety for his world tour of 20062008, and in 2010 began the Wall Live tour, the highest-grossing of all time by a solo artist.
What is the last name of the person who co-founded Pink Floyd?
