Which empire or dynasty emphasized unity of the empire, had government officials who had to pass a test, and saw the opening of the silk road? a.) mauryan b.) zhou c.) han d.) gupta

The answer is C.) Han Dynasty.

During the Han Dynasty (206 B.C.E. - 220 C.E), China was brought under control by Lui Bang, who was a strong ruler, partly because he picked able bureaucrats who organized the new dynasty efficiently, which emphasized unity in the empire.Although government jobs in the Han Dynasty were occupied acording to heredity, the Chinese established an examination system that measured a young  person's knowledge of Confucian texts. Only those passing the tests were able to work in government job positions.Moreover, as population in China grew rapidly during this era, canals were built, and the road system expanded to improve communication and knowledge as well as the production of silk, which was the most important export product. This left the Chinese with the silk monopoly. As a consequence, they established the Silk Road: an ancient route which not only transported goods, but also exchanged the cultures of China, India, Persia, Arabia, Greek and Rome.
