The correct answer is - 25 miles.
The journey/postal/communication relay system established in the Mongol Empire had stations set on approximately 25 miles, though there were variations from around 20 to around 30 miles.
This system was set up because the empire was enormous, so the quick travel of information was key for its functioning and proper organization.
The system, known as yam or ortoo, was very simple but very effective. For the means of travel the horse was the animal that was used, and the Mongols estimated the distance at which a single horse can be giving its maximum in speed, so they put up stations at distances where the horse's speed will start to decline because of exhaustion. The rider of the horse was either giving the message to another rider, or he was taking food and water with him, as well as a new, rested horse, and continued to the other station.
The correct answer is : Twenty-First.
The Twenty-First amendment repealed the 18th amendment, which introduced the Prohibition (of alcoholic beverages in the US).
Answer:
Xinhai Revolution or 辛亥革命
Explanation:
There were multiple revolutions during the Qing Dynasty, such as the Revolt of the Three Feudatories, White Lotus Rebellion, Eight Trigrams uprising of 1813, Taiping Rebellion, Nian Rebellion, Du Wenxiu Rebellion, Dungan revolts, and the Boxer Rebellion. This was to be understanded - the Qing were of the Manchu tribe - not of the Han, and so the Chinese do not like them much. However, the Qing have supressed them all, until the Xinhai Revolution. There were two main reasons why they were succesful: the Qing was weak, foreign countries are all coming in and trying to get a piece of China. Another reason was their equipment was far more advanced then most other rebellions during the Qing: they had Western guns and bullets. So that was why they were so succesful.
