It was the world's longest humanmade structure at more than four thousand miles actually constructed from a series of smaller walls that were connected together built to guard against Mongol invaders.

Limiting competition, this is why they're frowned on today.
Answer:
The complex and powerful states, dynasties, and civilizations that emerged in East Asia were strongly influenced by the environments in which they prospered.
Explanation:
What were the geologic and geographic advantages favoring certain locations that facilitated the establishment of villages and towns — some of which grew into cities — in various regions of East Asia? What role did climate play in enabling powerful states, and eventually agrarian civilizations, to appear in some areas while other locations remained better suited for foraging? Let’s begin to answer these questions with a story about floods in China.
China’s two great rivers — the Yangtze and the Yellow — have been susceptible to regular flooding for as long as we can measure in the historical and geological record; nothing, however, can compare to the catastrophic floods of August 19, 1931. In just one day the Yangtze River rose an astonishing 53 feet above its normal level, unleashing some of the most destructive floodwaters ever seen. These floods were a product of a “perfect storm” of conditions — monsoons, heavy snowmelt, and tremendous and unexpected rains that pounded huge areas of southern China. As all this water poured into the Yangtze’s tributaries, the river rose until it burst its banks for hundreds of miles. The results were devastating — 40 million people impacted, 24 million forced to relocate, and more than 140,000 people drowned. An area the size of Oklahoma was underwater, and the southern capital city of Nanjing was flooded for six weeks.
<span>The government's continuous changing of American Indian policy caused distrust of the federal government among American Indians. They never knew where they stood and what the situation was like - the government kept changing their policy and thus their way of living was also constantly modified. This made American Indians wary of the American government and they started trusting it less and less over time.</span>
The north and south began o use conscription early in the war to ensure that they had enough people in their army fighting in the warfront.
<u>Explanation:</u>
The conscription act passed by the US congress during the civil war demanded that all citizens between the age of 20 and 45 have to join the military to serve in the war. The conscription also mentioned aliens who required the citizenship of US. In order to be exempted from the military service people had to pay $300 which was a high sum at that time.
This meant that only the rich could afford exemption and this led to revolts in many parts of US. The Draft Riots of New York is an example. The confederate states government also passed the conscription draft to enhance the strength of their military force.
