Which best prevented the government from maintaining control at the end of the tang dynasty?
the lack of penalties for breaking laws
the inability to appoint skilled officials
the enormous size of the empire
the lack of crops due to drought

The correct answer is Option C) The enormous size of the Empire

Tang Dynasty was one of the largest empires that had existed uptil that time. It consisted of thousands of square kilometers of land that included various ethnicities, languages and cultures.

While building such an Empire was managable the government was not able to maintain control over the population. More and more rebellions started to occur in towns and villages away from the capital, eventually leading to the collapse.
