In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Example Input: Passage: Caspar David Friedrich was born on 5 September 1774, in Greifswald, Swedish Pomerania, on the Baltic coast of Germany. The sixth of ten children, he was brought up in the strict Lutheran creed of his father Adolf Gottlieb Friedrich, a candle-maker and soap boiler. Records of the family's financial circumstances are contradictory; while some sources indicate the children were privately tutored, others record that they were raised in relative poverty. Caspar David was familiar with death from an early age. His mother, Sophie Dorothea Bechly, died in 1781 when he was just seven. A year later, his sister Elisabeth died, while a second sister, Maria, succumbed to typhus in 1791. Arguably the greatest tragedy of his childhood happened in 1787 when his brother Johann Christoffer died: at the age of thirteen, Caspar David witnessed his younger brother fall through the ice of a frozen lake, and drown. Some accounts suggest that Johann Christoffer perished while trying to rescue Caspar David, who was also in danger on the ice.
Friedrich began his formal study of art in 1790 as a private student of artist Johann Gottfried Quistorp at the University of Greifswald in his home city, at which the art department is now named Caspar-David-Friedrich-Institut in his honour. Quistorp took his students on outdoor drawing excursions; as a result, Friedrich was encouraged to sketch from life at an early age. Through Quistorp, Friedrich met and was subsequently influenced by the theologian Ludwig Gotthard Kosegarten, who taught that nature was a revelation of God. Quistorp introduced Friedrich to the work of the German 17th-century artist Adam Elsheimer, whose works often included religious subjects dominated by landscape, and nocturnal subjects. During this period he also studied literature and aesthetics with Swedish professor Thomas Thorild. Four years later Friedrich entered the prestigious Academy of Copenhagen, where he began his education by making copies of casts from antique sculptures before proceeding to drawing from life. Living in Copenhagen afforded the young painter access to the Royal Picture Gallery's collection of 17th-century Dutch landscape painting. At the Academy he studied under teachers such as Christian August Lorentzen and the landscape painter Jens Juel. These artists were inspired by the Sturm und Drang movement and represented a midpoint between the dramatic intensity and expressive manner of the budding Romantic aesthetic and the waning neo-classical ideal. Mood was paramount, and influence was drawn from such sources as the Icelandic legend of Edda, the poems of Ossian and Norse mythology. 
Question: What is the full name of the man who taught taught that nature was a revelation of God to the person who lost his mother when he was seven?
Example Output: Ludwig Gotthard Kosegarten.

Example Input: Passage: Biographer Hannah Fink estimated that Oliver produced 290 works over a career of 22 years. Of these, public art works are Oliver's best known sculptures. These include Eyrie, created for Adelaide's Hyatt Hotel in 1993, and Magnolia and Palm, commissioned in 1999 by the Sydney Botanical Gardens, as part of the Sydney Sculpture Walk. That same year, Big Feathers was commissioned for the Queen Street Mall in Brisbane. It comprises two large feather-shaped forms suspended above the pedestrian precinct, representing "Queen Street's history of parades as well as the mall's connection between earth and sky".In 2000, Oliver's piece Entwine was a finalist in the inaugural Helen Lempriere National Sculpture Award, while in the following year, Oliver won the University of New South Wales inaugural sculpture commission competition, with her three-metre-high Globe. Other success followed, when Trace was selected for the National Gallery of Australia's 2002 National Sculpture Prize exhibition.In August 2002 she was one of five artists shortlisted by the Australian Government for a project to produce a public artwork celebrating the centenary of women's suffrage in Australia.By the 2000s most of Oliver's output constituted commissioned pieces, whether public or private. The most substantial of these is Vine, a 16.5 metre high sculpture installed as part of the $400 million refurbishment of the Sydney Hilton. Taking twelve months to create and requiring a budget of up to half million dollars, the work was completed in 2005. The sculpture was fabricated from 380 kilograms of aluminium, and assembled by a team of eight Croatian welders.By 2006, Oliver had held 18 solo exhibitions of her work, half of them at Roslyn Oxley9 Gallery, which represented her throughout her career as a sculptor. Only one of those solo exhibitions was held outside Australia: a 1992 exhibition at Auckland City Gallery. However, Oliver was represented in numerous international group shows, including five during the period 1983 to 1984, around the time she completed her master's degree in London. Four of the group shows at that time were in the United Kingdom; the fifth was at the Museum of Traditional Industries in Kyoto. Subsequent international group shows included 'Five Australian Artists' at Brest's Centre Culturale in 1988, the year she undertook an artist's residency in that city. Later group shows of which Oliver was part included 'Prospect '93' at the Frankfurter Kunstverein, 'Systems End: Contemporary Art in Australia', which exhibited in several east Asian galleries in 1996, and the Beijing International Biennale in 2003. 
Question: What is the name of the sculpture that was fabricated from 380 kilograms of aluminium, and assembled by a team of eight Croatian welders?
Example Output: Vine.

Example Input: Passage: The United States Exploring Expedition led by Lieutenant Charles Wilkes was tasked with a vast survey of the Pacific Ocean starting in 1838. In September 1840 they arrived in Honolulu, where repairs to the ships took longer than expected. Wilkes decided to spend the winter in Hawaii and take the opportunity to explore its volcanoes while waiting for better weather to continue the expedition. King Kamehameha III assigned American medical missionary Dr. Gerrit P. Judd to the expedition as a translator.Wilkes sailed to Hilo on the island of Hawaiʻi and decided to climb Mauna Loa first, since it looked easier than Mauna Kea. On December 14 he hired about 200 porters, but after he left he realized only about half the equipment had been taken, so he had to hire more Hawaiians at higher pay. When they reached Kīlauea after two days, their guide Puhano headed off to the established ʻAinapō Trail. Wilkes did not want to head back downhill so he blazed his own way through dense forest directed by a compass. The Hawaiians were offended by the waste of sacred trees which did not help morale. At about 6,000 feet (1,800 m) elevation they established a camp called "Sunday Station" at the edge of the forest.
Two guides joined them at Sunday Station: Keaweehu, "the bird-catcher" and another whose Hawaiian name is not recorded, called "ragsdale". Although Wilkes thought he was almost to the summit, the guides knew they were less than halfway up. Since there was no water at Sunday Station, porters had to be sent back ten miles (16 km) to a lava tube on ʻAinapō Trail which had a known supply. After an entire day replenishing stocks, they continued up to a second camp they called "Recruiting Station" at about 9,000 feet (2,700 m) elevation. After another full day's hike they established "Flag Station" on December 22, and by this time were on the ʻAinapō Trail. Most of the porters were sent back down to get another load. 
Question: What is the full name of the man that offended native Hawaiians by wasting sacred trees?
Example Output:
Charles Wilkes.
