The correct answer is B.
The Neolithic Revolution was characterized by the radical transformation of the human way of life, as societies stopped to be nomadic and started to be sedentary, and there was a transition from a hunter-gathered economy to an economy based on agriculture and raising livestock. Birth rates rose spectacularly and this brought an important population growth.
By 1890, the United States had by far the world's most productive economy. American industry produced twice as much as its closest competitor--Britain. But the United States was not a great military or diplomatic power. Its army numbered less than 30,000 troops, and its navy had only about 10,000 seamen. Britain's army was five times the size of its American counterpart, and its navy was ten times bigger. The United States' military was small because the country was situated between two large oceans and was surrounded by weak or friendly nations. It faced no serious military threats and had little interest in asserting military power overseas.<span>
During the late 19th century, the idea that the United States had a special mission to uplift "backward" people around the world also commanded growing support. The mainstream Protestant religious denominations established religion missions in Africa and Asia, including 500 missions in China by 1890.</span>
The United States Congress is the department that establishes the post office and roads. Congress was granted the power to manage the post office and the transport network, by the Articles of Confederation. The reason why the road network is part of the Postal Service is because originally the roads were created to facilitate the transport of the post to various outlying areas in the USA. It is fascinating to realize how important it was to deliver the post to its destination.
Feudalism helped protect communities from the violence and warfare that broke out after the fall of Rome and the collapse of strong central government in Western Europe. Feudalism secured Western Europe's society and kept out powerful invaders. Feudalism helped restore trade. Lords repaired bridges and roads.
