Which positive change occurred in China as a result of Ming dynasty politics

Self governing religious communities

Increase agricultural output

An end to taxes

The rise of Tokugawa

The right answer is the increase of agricultural output, the Ming dinasty ruled China for almost 300 years (1368-1644) and enjoyed stability and prosperity, reforming the government and making more efficient use of the land, one of the things that made this increase possible was taxes, what excludes the third option. As for the first option, Ming government persecuted to some extent Christian and Muslims communities, and for the fourth, Tokugawa was a dinastic government in Japan, not China.
