TASK DEFINITION: In this task, you're given a passage, further information available on a particular linked term from the statement, and a question. Your job is to generate the answer to the question by using the information provided. If there is no clear answer obtainable, output 'none'.
PROBLEM: Passage: Population densities of mistletoebirds recorded around Australia vary from 0 to 2 birds per hectare with a mean of 0.35 birds per hectare (in areas unaffected by agriculture), where the largest concentration was found in the Kakadu National Park, Northern Territory. The longevity of a mistletoebird has been recorded in southern Queensland where a banded adult male was recaptured near the banding site after 9 years. Mistletoebirds vocally mimic other birds. Heard in all seasons and given by both sexes, they have been recorded mimicking the mulga parrot ( Psephotus varius) as well as more than 25 different species of passerines. Predators known to have taken mistletoebird nestlings are the grey shrike-thrush (Colluricincla harmonica), pied butcherbird (Cracticus nigrogularis), pied currawong (Strepera graculina) and the Australian raven (Corvus coronoides). Nests have also been parasitized by a number of cuckoo species including the horsfield bronze cuckoo (Chrysococcyx basalis) and the fan-tailed cuckoo (Cuculus pyrrhophanus).
Link Information: It covers an area of 19804 km2, extending nearly 200 kilometres from north to south and over 100 kilometres from east to west. Question: What is the size of the park where the largest concentration of Mistletoebirds can be found?

SOLUTION: Answer: 19804 km2

PROBLEM: Passage: The Colony of Vancouver Island had been created in 1849 to bolster British claims to the whole island and the adjacent Gulf Islands, and to provide a North Pacific home port for the Royal Navy at Esquimalt. By the mid-1850s, the Island Colony's non-indigenous population was around 800 people; a mix of mostly British, French-Canadian, Metis, Hawaiians, but with handfuls of Iroquoians and Cree in the employ of the fur company, and a few Belgian and French Oblate priests (thousands of First Nations died due to the smallpox epidemic). Three years earlier, the Treaty of Washington had established the boundary between British North America and the United States of America west of the Rocky Mountains along the 49th parallel. The mainland area of present-day British Columbia, Canada was an unorganised territory under British sovereignty until 1858. The region was under the de facto administration of the Hudson's Bay Company, and its regional chief executive, James Douglas, who also happened to be Governor of Vancouver Island. The region was informally given the name New Caledonia, after the fur-trading district which covered the central and northern interior of the mainland west of the Rockies.
Link Information: Even before the partition of the Columbia Department by the Oregon Treaty in 1846, New Caledonia was often used to describe anywhere on the mainland not in the Columbia Department, such as Fort Langley in the Fraser Valley. Question: In what year was the region given the name New Caledonia?

SOLUTION: Answer: 1846

PROBLEM: Passage: After Antwerp, Albers was engaged as Principal Baritone at the Opera de Bordeaux and went on to sing at the Royal Opera House in London and the Opera de Monte-Carlo. He was engaged by the Metropolitan Opera in 1898 and sang with the company both on tour and in New York City. He made his company debut on 8 November 1898 as Mercutio in the Met's touring performance of Romeo et Juliette in Chicago. He remained with the company through 1899, appearing 36 times in eight different operas and tackling his first Wagnerian role, Wolfram in Tannhauser. On his return to Europe he sang regularly at the Theatre de la Monnaie in Brussels from 1901 to 1906 and added several more Wagnerian roles to his repertoire: Telramund in Lohengrin; Hans Sachs in Die Meistersinger von Nurnberg; Wotan in Das Rheingold, Siegfried, and Die Walkure; and Kurwenal in Tristan und Isolde. A highly versatile singer, he also appeared in the title roles of La Monnaie's productions of Hamlet, Rigoletto, Herodiade, and Le roi Arthus, as well as singing Count di Luna in Il trovatore, Iago in Otello, and Baron Scarpia in Tosca.
