Which statements describe political achievements under the Ming dynasty in China?

Answer:
Ming political achievements
- A civil service helped run the empire efficiently.
- The first Ming emperor overthrew the hated mongols.
Explanation:
The civil service had existed for many centuries before, but the Ming dynasty perfected it and stiffened up requirements for joining it. Mandarins - top court officials - had to be experts in Confucian knowledge and classics. The Ming restored Chinese local rule over the empire following the Mongol-dominated Yuan dynasty. In the early 15th century CE, the Ming court promoted maritime exploration that was very successful, but those deeds are not political achievements.
