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.

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

[EX Q]: Passage: Daphne Blake is a high school student who has a semi-popular web show discussing the possibility of aliens and supernatural occurrences. Velma Dinkley is Daphne's supportive yet critical online friend, who believes there is a logical explanation for everything. After Velma web chats Daphne following her latest episode, she reveals to Velma that her parents will be moving to Ridge Valley, where Velma currently goes to high school.
After having a perfect morning at home, Daphne embarks on her first day at Ridge Valley High. She quickly meets Carol, her senior advisor, who shows her the school's expansive collection of advanced technology from Bloom Innovative, a famous technology company. While on her tour, Daphne runs into Velma, who does not speak to her. Later that afternoon, Daphne sees a student named Spencer walk into an open locker as if he were in a trance.
At home, Daphne's father reveals that he has sheltered Daphne all her life, going to extreme lengths to follow her around everywhere in an attempt to make Daphne's life "perfect". Shocked and frustrated at her father, Daphne vows to do everything on her own without her father's assistance. The next day, Daphne gets into a heated argument with Velma over their science project, which Velma intentionally sabotaged. The argument results in the girls getting sent to the principal's office, who puts them on "the best couch for conflict resolution". The couch helps the girls put aside their differences, and Velma reveals she was protecting Daphne because she knew of the strange happenings at the school. Daphne and Velma vow to solve the mystery of the disappearing students.
[EX A]: What are the full names of the friends who go to Ridge Valley High?

[EX Q]: Passage: Hazards stemming from volcanic activity at Ubinas are mainly the fallout from explosive eruptions, lahars of different origins, large landslides that can generate debris flows and pyroclastic flows. Small explosive eruptions are the most likely occurrences at Ubinas, while large Plinian eruptions are considerably less likely. The area of the cone itself is the area most likely to be affected by volcanic phenomena, while pyroclastic flows and lahars are a danger for the valleys that drain Ubinas in southeastern direction and landslides are hazardous for an area of the southern flank. The town closest to the volcano is only 4 kilometres (2.5 mi) away from Ubinas. Large Plinian eruptions could have effects on the city of Arequipa.The Peruvian INGEMMET geological service monitors the seismic activity, any deformation of the mountain, and hot spring and gas composition at Ubinas. It regularly publishes a report on the activity of Ubinas. Hazard maps were created during the 2006 eruptive event to show the relative risk in various locations around the volcano, which is graded in a three-zone scheme with one high-risk, one intermediate-risk and one low-risk zone. A contingency map was created to show and explain the procedures to follow in case of various eruption scenarios. Both maps were widely disseminated after publication to aid in the response to future eruptions.
[EX A]:
What is the name of the thing that hazard maps show risks around in three zones?
