Input: Article: The Mongol Yuan dynasty, through the Bureau of Buddhist and Tibetan Affairs, or Xuanzheng Yuan, ruled Tibet through a top-level administrative department. One of the department's purposes was to select a dpon-chen ('great administrator'), usually appointed by the lama and confirmed by the Mongol emperor in Beijing. The Sakya lama retained a degree of autonomy, acting as the political authority of the region, while the dpon-chen held administrative and military power. Mongol rule of Tibet remained separate from the main provinces of China, but the region existed under the administration of the Yuan dynasty. If the Sakya lama ever came into conflict with the dpon-chen, the dpon-chen had the authority to send Chinese troops into the region.

Now answer this question: Which dynasty ruled Tibet through a top-level administrative department?

Output: Mongol Yuan

Input: Article: Tracks of the Northern Pacific Railroad (NPR) reached Montana from the west in 1881 and from the east in 1882. However, the railroad played a major role in sparking tensions with Native American tribes in the 1870s. Jay Cooke, the NPR president launched major surveys into the Yellowstone valley in 1871, 1872 and 1873 which were challenged forcefully by the Sioux under chief Sitting Bull. These clashes, in part, contributed to the Panic of 1873 which delayed construction of the railroad into Montana. Surveys in 1874, 1875 and 1876 helped spark the Great Sioux War of 1876. The transcontinental NPR was completed on September 8, 1883, at Gold Creek.

Now answer this question: What years were the railroad challenged by Chief Sitting Bull?

Output: 1871, 1872 and 1873

Input: Article: Early Islamic philosophy and Islamic metaphysics, imbued as it is with Islamic theology, distinguishes more clearly than Aristotelianism between essence and existence. Whereas existence is the domain of the contingent and the accidental, essence endures within a being beyond the accidental.

The search for a definitive Islamic philosophy separate from Occasionalism can be seen in what is left of his work.

Now answer this question: What is early Islamic metaphysics imbued with?

Output:
Islamic theology
