Input: Han dynasty
The emperor was at the pinnacle of Han society. He presided over the Han government but shared power with both the nobility and appointed ministers who came largely from the scholarly gentry class. The Han Empire was divided into areas directly controlled by the central government using an innovation inherited from the Qin known as commanderies, and a number of semi-autonomous kingdoms. These kingdoms gradually lost all vestiges of their independence, particularly following the Rebellion of the Seven States. From the reign of Emperor Wu onward, the Chinese court officially sponsored Confucianism in education and court politics, synthesized with the cosmology of later scholars such as Dong Zhongshu. This policy endured until the fall of the Qing dynasty in AD 1911.

What innovation was acquired from the Qin?
Output: commanderies

Input: Westminster Abbey
Between 1042 and 1052 King Edward the Confessor began rebuilding St Peter's Abbey to provide himself with a royal burial church. It was the first church in England built in the Romanesque style. The building was not completed until around 1090 but was consecrated on 28 December 1065, only a week before Edward's death on 5 January 1066. A week later he was buried in the church, and nine years later his wife Edith was buried alongside him. His successor, Harold II, was probably crowned in the abbey, although the first documented coronation is that of William the Conqueror later the same year.

When did King Edward the Confessor die?

5 January 1066
