Final answer:
True, the Han emperors implemented strict regulations to prevent civil servants from doing special favors for friends, creating an honest and achievement-based bureaucracy, with systems like the Censorate to monitor and ensure accountability.
Step-by-step explanation:
The statement that Han emperors kept civil servants from doing special favors for their friends by implementing strict regulations is true. The Han Dynasty implemented a bureaucratic system that valued achievements and honesty over personal connections. Officials were not only promoted and demoted based on their performance but also rewarded according to the rank of their posts. Additionally, by having civil servants serve short terms and not in their native places, it minimized the chances of local favoritism and corruption. Furthermore, the existence of a governmental branch like the Censorate, which monitored all levels of government and could hold anyone accountable, including the emperor, ensured that misuses of power were kept in check.
