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: A remix album, titled Year Zero Remixed, was released in November 2007. Due to the expiration of his contract with Interscope Records, the album's release, marketing, and promotion were completely in Reznor's control. The album features remixes from artists including The Faint, Ladytron, Bill Laswell, Saul Williams, Olof Dreijer of The Knife, and Sam Fogarino of Interpol. Reznor himself strongly supports fan-made remixes of songs from the album, as evidenced by his decision to upload every song in multi-track form to the then-newly launched Nine Inch Nails remix website.  Instrumental versions of the songs on Year Zero are available at the site for download in multiple formats, including MP3, WAV, GarageBand, and Ableton Live formats.
A planned film adaption of Year Zero became a television project in 2007. Reznor met with various writers and pitched the idea to television networks. The 2007–08 Writers Guild of America strike affected the pre-production stage. Nevertheless, Reznor commented in 2008 that the project is "still churning along", and that he had begun working with American film producer Lawrence Bender. In 2010, Reznor started developing the Year Zero miniseries with HBO and BBC Worldwide Productions. Reznor and Bender collaborated with Carnivàle writer Daniel Knauf to create the science fiction epic. When asked about the miniseries during an "Ask Me Anything" session on Reddit on November 13, 2012, Reznor said it was "currently in a holding state" and explained, "We [Reznor and Sheridan] didn't find the right match with a writer, and really have been avoiding doing what we should have done from the beginning: write it ourselves. [...] This project means a lot to me and will see the light of day in one form or another." In 2017, during an interview promoting new Nine Inch Nails EP Add Violence, Reznor said that "They got so far as hiring a writer for it, but then it fell to shit because we never had the right writer. I should have just done it [myself].".
[A]: What is the last name of the person whose contract expired?


[Q]: 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.
[A]: What was the name of the person who planned a traversal of the Northwest Passage?


[Q]: Passage: Human habitation in the Sierra Nevada region of California reaches back  8,000 to 10,000 years ago. Historically attested Native American populations, such as the Sierra Miwok, Mono and Paiute, belong to the Uto-Aztecan and Utian phyla.
In the mid-19th century, a band of Native Americans called the Ahwahnechee lived in Yosemite Valley. The California Gold Rush greatly increased the number of non-indigenous people in the region.  Tensions between Native Americans and white settlers escalated into the Mariposa War. As part of this conflict, settler James Savage led the Mariposa Battalion into Yosemite Valley in 1851, in pursuit of Ahwaneechees led by Chief Tenaya.  Accounts from the battalion, especially from Dr. Lafayette Bunnell, popularized Yosemite Valley as a scenic wonder.
In 1864, Yosemite Valley and the Mariposa Grove of giant sequoia trees were transferred from federal to state ownership. Yosemite pioneer Galen Clark became the park's first guardian. Conditions in Yosemite Valley were made more hospitable to people and access to the park was improved in the late 19th century. Naturalist John Muir and others became increasingly alarmed about the excessive exploitation of the area. Their efforts helped establish Yosemite National Park in 1890. Yosemite Valley and the Mariposa Grove were added to the national park in 1906.
The United States Army had jurisdiction over the national park from 1891 to 1914, followed by a brief period of civilian stewardship. The newly formed National Park Service took over the park's administration in 1916. Improvements to the park helped to increase visitation during this time. Preservationists led by Muir and the Sierra Club failed to save Hetch Hetchy Valley from becoming a reservoir in 1923. In 1964, 89 percent of the park was set aside in a highly protected wilderness area, and other protected areas were added adjacent to the park. The once-famous Yosemite Firefall, created by pushing red hot embers off a cliff near Glacier Point at night, was discontinued in the mid-to-late 20th century along with other activities that were deemed to be inconsistent with protection of the national park.
