Question: Passage: The Tibetan Empire emerged in the 7th century, but with the fall of the empire the region soon divided into a variety of territories. The bulk of western and central Tibet (Ü-Tsang) was often at least nominally unified under a series of Tibetan governments in Lhasa, Shigatse, or nearby locations; these governments were at various times under Mongol and Chinese overlordship. The eastern regions of Kham and Amdo often maintained a more decentralized indigenous political structure, being divided among a number of small principalities and tribal groups, while also often falling more directly under Chinese rule after the Battle of Chamdo; most of this area was eventually incorporated into the Chinese provinces of Sichuan and Qinghai. The current borders of Tibet were generally established in the 18th century. Question: Which Chinese provinces used to be the eastern part of Tibet?

Answer: Sichuan and Qinghai

Question: Passage: Between January and May 1673, the Dutch East India Company forcibly took the island, before English reinforcements restored English East India Company control. The company experienced difficulty attracting new immigrants, and sentiments of unrest and rebellion fomented among the inhabitants. Ecological problems, including deforestation, soil erosion, vermin and drought, led Governor Isaac Pyke to suggest in 1715 that the population be moved to Mauritius, but this was not acted upon and the company continued to subsidise the community because of the island's strategic location. A census in 1723 recorded 1,110 people, including 610 slaves. Question: How many slaves were on the island in 1723?

Answer:
610
