Background information: This passage was written by a Tang Dynasty official in 819 CE, in response to the growth of Buddhism in China. Buddha was a western barbarian. He did not understand Chinese, and wore clothes of different cut and make. His tongue did not speak of the importance of the ancestors or the ancient kings; his body did not wear the clothes prescribed by our culture. He did not recognize the importance of the relationship between ministers towards his sovereign, nor the sentiments of the child towards his parents. Suppose he were still living, and came to the capital to ask for an audience with the Emperor. Suppose it pleased Your Majesty to lodge and receive him, then Your Majesty would surely not grant him more than one interview. . . . Then you would have him escorted across the frontier, but you would prevent him from leading the people into error. Which of these inferences can you make based on the document and your knowledge of Chinese history? China had long been concerned about corruption of its culture. Most Chinese practiced Buddhism in the Tang Dynasty. China dominated global trade from 800 to 1600. Confucianism was on the decline in the Tang Dynasty.

It is 800

Explanation:

because 800-1600=800+819=1619

the first historical instance of china engaging in internationalism was during the han dynasty.[1] at the start of the han dynasty, the huns in the north were attacking the frontiers of han and trying to obtain riches. emperor wu of han wanted to gain an alliance with a country called dayuezhi so the two countries could join together and fight against the huns.[2] to obtain this alliance, emperor wu sent zhang qian to the west to establish economic and cultural connections.[2] history records that during the han dynasty there were four primary avenues of contact between china and europe. they included the northern land route, the central land route, the southern sea route, and the far southern sea route.[1] the most famous of these routes is the central land route, or the classical silk road, comprising a network of roads stretching from northwest china to the ports of syria and the black sea, which passed through the oasis of the turkestans and northern persia.[1] the silk road was significant for chinese emperors because it provided dominance over central asia by developing resources and provided new markets for the export of china's most valuable resources.[1]
