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.

[Q]: 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 Scotland—a quarter of Scottish capital was lost in the enterprise—and 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.
[A]: In what year did the African population in the thirteen colonies contribute to 10%?


[Q]: Passage: In the late 19th and early 20th centuries, child vaudevillian Buster Keaton stays in boarding houses, rides in train boxcars, and performs with his mother and father in a knock-about (physical comedy) act called The Three Keatons. As a young man Keaton travels on his own to Hollywood and tricks his way onto the grounds of silent-film studio Famous Studio as a workman carrying a board, as in one of his trademark comic bits. 
Sneaking onto a set, he attracts the attention of a young casting director, Gloria Brent. He demonstrates his type of physical comedy to a director Kurt Bergner, whom he does not impress. But Gloria recognizes his talent and recommends him to studio head Larry Winters, who offers him a contract. Keaton begins to get small parts in other people's pictures. As his comic talent becomes more apparent and his fame and money-making power grows, he is offered a contract to direct and star in his own silent films.
Dissatisfied with not sharing the profits of his films, he is told that he must invest in his own pictures in order to profit-share. He does in "The Gambler", which is released at the same time as Al Jolson's blockbuster talkie, "The Jazz Singer", reducing public interest in it. Buster struggles to adapt to performing in talking pictures.
[A]: What is the full name of the person who fails to impress Kurt Bergner?


[Q]: Passage: Musically, Love's work with Hole and her solo efforts have been characterized as alternative rock; Hole's early material, however, was described by critics as being stylistically closer to grindcore and aggressive punk rock. Spin's October 1991 review of Hole's first album noted Love's layering of harsh and abrasive riffs buried more sophisticated musical arrangements. In 1998, she stated that Hole had "always been a pop band. We always had a subtext of pop. I always talked about it, if you go back ... what'll sound like some weird Sonic Youth tuning back then to you was sounding like the Raspberries to me, in my demented pop framework."Love's lyrical content is composed from a female's point of view, and her lyrics have been described as "literate and mordant" and noted by scholars for "articulating a third-wave feminist consciousness." Simon Reynolds, in reviewing Hole's debut album, noted: "Ms. Love's songs explore the full spectrum of female emotions, from vulnerability to rage. The songs are fueled by adolescent traumas, feelings of disgust about the body, passionate friendships with women and the desire to escape domesticity. Her lyrical style could be described as emotional nudism." Journalist and critic Kim France, in critiquing Love's lyrics, referred to her as a "dark genius" and likened her work to that of Anne Sexton.Love has remarked that lyrics have always been the most important component of songwriting for her: "The important thing for me...  is it has to look good on the page. I mean, you can love Led Zeppelin and not love their lyrics...  but I made a big effort in my career to have what’s on the page mean something." A great deal of her songwriting has been diaristic in nature. Common themes present in Love's songs during her early career included body image, rape, suicide, conformity, elitism, pregnancy, prostitution, and death. In a 1991 interview with Everett True, she said: "I try to place [beautiful imagery] next to fucked up imagery, because that's how I view things ... I sometimes feel that no one's taken the time to write about certain things in rock, that there's a certain female point of view that's never been given space."Critics have noted that Love's later musical work is more lyrically introspective. Celebrity Skin and America's Sweetheart are lyrically centered on celebrity life, Hollywood, and drug addiction, while continuing Love's interest in vanity and body image. Nobody's Daughter was lyrically reflective of Love's past relationships and her struggle for sobriety, with the majority of its lyrics written while she was in rehab in 2006.
[A]:
What is the name of the song that reflected on the person who worked with Hole's struggle for sobriety?
