Answer:
They're the birth place of Democracy.
Explanation:
Ancient Greece was considered as the first civilizations that introduced the concept of Democracy.
The building in Ancient Greece was designed to accommodate a lot of audiences facing one specific direction where the speaker can present his/her case. The Roman civilization adopted this building and some principles from Greek's democracy.
American leaders in the past used these concept as a replacement for British' monarchy. They found that mimicking the building can be a source of inspiration that remind them about the core foundation of democratic government.
The other-race effect refers to a bias with respect to the recognition of other people's faces.
The British tried to keep settlers off of the Indian Lands. They respected the land west of the Appalacians as the Native Americans land. After the Treaty of Paris the Revolutionary War ended between the USA and Britain the west was opened up. Great Britain abandoned the claims to the trans-Appalachian region. The Native American nations were left to take "care" of their neighbors.
