Answer:
I can say that the most likely cause of the increase in scientific achievement under the Choson dynasty was the establishment of the Royal Academy of Sciences during the reign of King Sejong the Great.The Royal Academy of Sciences was a research institution that focused on scientific research, mathematics, and astronomy. This led to an increase in scientific knowledge and the development of new technologies, such as the creation of the Korean alphabet known as "Hangul" which improved literacy rate in the country.
Furthermore, the Choson Dynasty also had a highly centralized government and a strong bureaucracy, which allowed for the promotion of education and learning. The government also supported the development of technology and science by providing resources and funding for research.
In addition to that, the Neo-Confucianism philosophy was also a significant factor that contributed to the increase in scientific achievement during the Choson Dynasty. This philosophy promoted the idea of the pursuit of knowledge and learning for the betterment of society.
Therefore, the combination of the establishment of the Royal Academy of Sciences, a strong government, and the promotion of education through Neo-Confucianism led to the increase in scientific achievement under the Choson dynasty.
