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.
One example: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Question: Who believes Fagin's gang make wallets and handkerchiefs?
Solution is here: Oliver.
Explanation: In the sentence "He believes they make wallets and handkerchiefs", the pronoun "he" refers to name "Oliver".

Now, solve this: Passage: Ratanakiri has been occupied since at least the Stone or Bronze Age, and trade between the region's highlanders and towns along the Gulf of Thailand dates to at least the 4th century A.D. The region was invaded by Annamites, the Cham, the Khmer, and the Thai during its early history, but no empire ever brought the area under centralized control. From the 13th century or earlier until the 19th century, highland villages were often raided by Khmer, Lao, and Thai slave traders. The region was conquered by local Laotian rulers in the 18th century and then by the Thai in the 19th century. The area was incorporated into French Indochina in 1893, and colonial rule replaced slave trading. The French built huge rubber plantations, especially in Labansiek (present-day Banlung); indigenous workers were used for construction and rubber harvesting. While under French control, the land comprising present-day Ratanakiri was transferred from Siam (Thailand) to Laos and then to Cambodia. Although highland groups initially resisted their colonial rulers, by the end of the colonial era in 1953 they had been subdued.Ratanakiri Province was created in 1959 from land that had been the eastern area of Stung Treng Province. The name Ratanakiri () is formed from the Khmer words (ratana "gem" from Sanskrit ratna) and (kiri "mountain" from Sanskrit giri), describing two features for which the province is known. During the 1950s and 1960s, Norodom Sihanouk instituted a development and Khmerization campaign in northeast Cambodia that was designed to bring villages under government control, limit the influence of insurgents in the area, and "modernize" indigenous communities. Some Khmer Loeu were forcibly moved to the lowlands to be educated in Khmer language and culture, ethnic Khmer from elsewhere in Cambodia were moved into the province, and roads and large rubber plantations were built. After facing harsh working conditions and sometimes involuntary labor on the plantations, many Khmer Loeu left their traditional homes and moved farther from provincial towns. In 1968, tensions led to an uprising by the Brao in which several Khmer were killed. The government responded harshly, torching settlements and killing hundreds of villagers.
Question: What is the former name of the area where the French built huge rubber plantations?
Solution:
Banlung.
