The accomplishments of the Ming Dynasty include:
A. reconstructing the Great Wall and constructing large ships for exploration
D. building of the Forbidden City and developing paper money for trading
Both of these options highlight significant achievements of the Ming Dynasty, such as the reconstruction of the Great Wall, the construction of the Forbidden City, and advancements in trade, including paper money.
While C mentions the reconstruction of Beijing, it is not as prominent as the construction of the Forbidden City, which is a major landmark from the Ming era. Option B includes inventions and constructions that are not specifically tied to the Ming Dynasty.
So, the best answers would be A and D.
