Teacher: Now, understand the problem? Solve this instance: Passage: Following the Xinhai Revolution against the Qing dynasty in 1912, Qing soldiers were disarmed and escorted out of Tibet Area (U-Tsang). The region subsequently declared its independence in 1913 without recognition by the subsequent Chinese Republican government. Later, Lhasa took control of the western part of Xikang, China. The region maintained its autonomy until 1951 when, following the Battle of Chamdo, Tibet became incorporated into the People's Republic of China, and the previous Tibetan government was abolished in 1959 after a failed uprising. Today, China governs western and central Tibet as the Tibet Autonomous Region while the eastern areas are now mostly ethnic autonomous prefectures within Sichuan, Qinghai and other neighbouring provinces. There are tensions regarding Tibet's political status and dissident groups that are active in exile. It is also said that Tibetan activists in Tibet have been arrested or tortured.
Student:
