Final answer:
The correct actions taken by Wang Mang during his rule include "2) He minted new money and 4) He killed rebels".
Step-by-step explanation:
Wang Mang, who briefly interrupted the Han Dynasty with his Xin Dynasty, implemented significant changes during his rule. One notable action was the minting of new money. Wang Mang introduced a new currency system, attempting to stabilize the economy and consolidate his authority. However, the abrupt changes in the currency system led to economic disruptions and challenges.
Additionally, Wang Mang faced internal opposition, and to suppress rebellion, he resorted to harsh measures, including the execution of rebels. This use of force aimed to maintain control and quell dissent, but it ultimately contributed to the unrest during his reign.While land reforms and floods are associated with Wang Mang's rule, the specific actions mentioned in options 1) and 3) are not accurate depictions of his policies.
The "2) minting of new money and 4) the suppression of rebels" are key actions that define Wang Mang's attempt to reshape governance and secure his position in a turbulent political landscape.
