Answer:
If I had the power to add one amendment to the US constitution, it would be to give <em><u>basic labor rights.</u></em>
Explanation:
While the constitution talks out basic human rights, freedom of speech and even the right to bear arms, it does not provide any framework on how to manage an effective and healthy workforce fairly.
Some key points would be added e.g the right to a fair minimum wage, the right to health insurance, a work week of no more than 40 hours etc.
While it may have not been important in a society that was largely agricultural, in today's post-industrialization world, this is very important.
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.
