Explanation:

Now let's understand better each point

A) After the American Revolution in 1776, the Thirteen Colonies began to expand their territories beyond the Apalachee Mountains. This spread started at the beginning of the 19th century and it was based in a philosophical doctrine called Manifest Destiny. According to this idea, America's expansion to The West was God's will and should be incentivized. In this process that took almost sixty years, many Native American tribes would be massacred in order to develop a civilization.

B) This process is important because beyond the fact that maintain the economy strong, creates a reputation. After the Revolution, America should develop its international repute, and this is gain with new markets and international relations.

C) A strong and large navy was important not only to defend their trades, and borders but to maintain the political relationships. For example, in 1868, America obliged Japan to open its harbors to the world through the use of navy and military support.

D) As I said on the previous item, a strong navy and military support avoid America to be alienated from the foreign markets.
