You will be given a definition of a task first, then some input of the task.
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.

Passage: Ratanakiri or Ratanak Kiri (Khmer: រតនគិរី IPA: [ˌreə̯̆ʔ taʔ ˈnaʔ ki ˈriː]), is a province of northeast Cambodia. It borders the provinces of Mondulkiri to the south and Stung Treng to the west and the countries of Laos and Vietnam to the north and east, respectively. The province extends from the mountains of the Annamite Range in the north, across a hilly plateau between the Tonle San and Tonle Srepok rivers, to tropical deciduous forests in the south. In recent years, logging and mining have scarred Ratanakiri's environment, long known for its beauty.
For over a millennium, Ratanakiri has been occupied by the highland Khmer Loeu people, who are a minority elsewhere in Cambodia. During the region's early history, its Khmer Loeu inhabitants were exploited as slaves by neighboring empires. The slave trade economy ended during the French colonial era, but a harsh Khmerization campaign after Cambodia's independence again threatened Khmer Loeu ways of life.  The Khmer Rouge built its headquarters in the province in the 1960s, and bombing during the Vietnam War devastated the region. Today, rapid development in the province is altering traditional ways of life.
Ratanakiri is sparsely populated; its 184,000 residents make up just over 1% of the country's total population. Residents generally live in villages of 20 to 60 families and engage in subsistence shifting agriculture. Ratanakiri is among the least developed provinces of Cambodia. Its infrastructure is poor, and the local government is weak. Health indicators in Ratanakiri are extremely poor; men's life expectancy is 39 years, and women's is 43 years. Education levels are also low, with just under half of the population illiterate.
Output:
How many people live in the province that borders the provinces of Mondulkiri to the south and Stung Treng to the west?
