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: Sanders is a British colonial District Commissioner in Colonial Nigeria. He tries to rule his province fairly, including the various tribes comprising the Peoples of the River. He is regarded with respect by some and with fear by others, among whom he is referred to as "Sandi" and "Lord Sandi". He has an ally in Bosambo, a literate and educated chief (played by the American actor, Paul Robeson).
When Sanders goes on leave, another chief, King Mofolaba, spreads the rumour that "Sandi is dead." Inter-tribal war seems inevitable, and the situation is made worse by gun-runners and slavers.
His relief, Ferguson (known to the natives as Lord Ferguson), is unequal to the task; he is captured and killed by King Mofolaba. Sanders returns to restore peace. When Bosambo's wife Lilongo is kidnapped, the chief tracks down her kidnappers. Captured by them, he is saved by a relief force commanded by Sanders. Bosambo kills King Mofolaba and is subsequently named by Sanders as the King of the Peoples of the River.
What is the real name of Sandi?

Passage: Amundsen was born in Fredrikstad (around 80 km from Christiania (now Oslo)), Norway, in 1872, the son of a ship-owner. In 1893, he abandoned his medical studies at Christiania University and signed up as a seaman aboard the sealer Magdalena for a voyage to the Arctic. After several further voyages he qualified as a second mate; when not at sea, he developed his skills as a cross-country skier in the harsh environment of Norway's Hardangervidda plateau. In 1896, inspired by the polar exploits of his countryman Fridtjof Nansen, Amundsen joined the Belgian Antarctic Expedition as mate, aboard Belgica under Adrien de Gerlache. Early in 1898 the ship became trapped by pack ice in the Bellinghausen Sea, and was held fast for almost a year. The expedition thus became, involuntarily, the first to spend a complete winter in Antarctic waters, a period marked by depression, near-starvation, insanity, and scurvy among the crew. Amundsen remained dispassionate, recording everything and using the experience as an education in all aspects of polar exploration techniques, particularly aids, clothing and diet.Belgica's voyage marked the beginning of what became known as the Heroic Age of Antarctic Exploration, and was rapidly followed by expeditions from the United Kingdom, Sweden, Germany and France. However, on his return to Norway in 1899, Amundsen turned his attention northwards. Confident in his abilities to lead an expedition, he planned a traversal of the Northwest Passage, the then-uncharted sea route from the Atlantic to the Pacific through the labyrinth of north Canadian islands. Having earned his master's ticket, Amundsen acquired a small sloop, Gjøa, which he adapted for Arctic travel. He secured the patronage of King Oscar of Sweden and Norway, the support of Nansen, and sufficient financial backing to set out in June 1903 with a crew of six. The voyage lasted until 1906 and was wholly successful; the Northwest Passage, which defeated mariners for centuries, was finally conquered. At the age of 34 Amundsen became a national hero, in the first rank of polar explorers.In November 1906 the American Robert Peary returned from his latest unsuccessful quest for the North Pole, claiming a new Farthest North of 87° 6′—a record disputed by later historians. He immediately began raising funds for a further attempt. In July 1907 Dr Frederick Cook, a former shipmate of Amundsen's from Belgica, set off northwards on what was ostensibly a hunting trip but was rumoured to be an attempt on the North Pole. A month later Ernest Shackleton's Nimrod Expedition sailed for Antarctica, while Robert Falcon Scott was preparing a further expedition should Shackleton fail. Amundsen saw no reason to concede priority in the south to the British, and spoke publicly about the prospects of leading an Antarctic expedition—although his preferred goal remained the North Pole.
What was the name of the person who planned a traversal of the Northwest Passage?

Passage: Bowie's songs and stagecraft brought a new dimension to popular music in the early 1970s, strongly influencing both its immediate forms and its subsequent development. Bowie was a pioneer of glam rock, according to music historians Schinder and Schwartz, who credited Marc Bolan and Bowie with creating the genre. At the same time, he inspired the innovators of the punk rock music movement. When punk musicians were "noisily reclaiming the three-minute pop song in a show of public defiance", biographer David Buckley wrote that "Bowie almost completely abandoned traditional rock instrumentation." Bowie's record company promoted his unique status in popular music with the slogan, "There's old wave, there's new wave, and there's David Bowie".Musicologist James Perone credited Bowie with having "brought sophistication to rock music", and critical reviews frequently acknowledged the intellectual depth of his work and influence. The Human League founder Martyn Ware remarked that he had lived his life "as though he were an art installation." The BBC's arts editor Will Gompertz likened Bowie to Pablo Picasso, writing that he was "an innovative, visionary, restless artist who synthesised complex avant garde concepts into beautifully coherent works that touched the hearts and minds of millions". U2 lead singer Bono commented, "I like Bowie when he’s evenly pulled in the direction of being a pop star and Picasso, where he's right down the middle. That’s usually my favorite, when the songwriting is disciplined but the recording is not. I love when he's pulled equally in the directions of art and populism."Broadcaster John Peel contrasted Bowie with his progressive rock contemporaries, arguing that Bowie was "an interesting kind of fringe figure... on the outskirts of things". Peel said he "liked the idea of him reinventing himself... the one distinguishing feature about early-70s progressive rock was that it didn't progress. Before Bowie came along, people didn't want too much change". Buckley called the era "bloated, self-important, leather-clad, self-satisfied"; then Bowie "subverted the whole notion of what it was to be a rock star".
After Bowie there has been no other pop icon of his stature, because the pop world that produces these rock gods doesn't exist any more. ... The fierce partisanship of the cult of Bowie was also unique—its influence lasted longer and has been more creative than perhaps almost any other force within pop fandom.
