question:
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?
answer:
Answer: 19804 km2

Passage: The minesweeper departed Sasebo on 5 January 1966 for an "Operation Market Time" deployment off the coast of Vietnam. On the 9th she paused briefly at Kaohsiung to take on fuel and provisions. She arrived on her station south of Vung Tau on 14 January and patrolled the sea lanes in her area until relieved on 22 February. The minesweeper returned to Sasebo on 5 March to begin one and one-half months of upkeep and training. On 21 April Albatross sailed in company with Epping Forest (MCS-7), Warbler (MSC-206), and Peacock (MSC-198) for Chinhae, Korea and an exercise with the Republic of Korea Navy. Following the five-day exercise, she visited Kure on 29 April before returning to Sasebo on 4 May. Albatross got underway on 20 May for the South China Sea in company with Warbler. Her station was located off the tip of the Camau peninsula, and her patrol lasted through 9 July.

question:
Passage: Herpesviruses are a third group of common cancer-causing viruses. Two types of herpesviruses have been associated with cancer: the Epstein–Barr virus (EBV) and human herpesvirus 8 (HHV-8). EBV appears to cause all nonkeratinizing nasopharyngeal carcinomas and some cases of lymphoma, including Burkitt's lymphoma—the association is especially strong in Africa—and Hodgkin's disease. EBV has also been found in a variety of other types of cancer cells, although its role in causing these other cancers is not well established. KSHV/HHV-8 causes all cases of Kaposi's sarcoma, and has been found in some cases of a cancer-related condition called Castleman's disease. Studies involving other kinds of cancer, particularly prostate cancer, have been inconsistent. Both of these herpesviruses are commonly found in cancerous cells of primary effusion lymphoma. Herpesviruses also cause cancer in animals, especially leukemias and lymphomas.
