Answer:
A unique new American culture would be created from the blending of diverse ethnicities
Explanation:
The melting pot theory is an analogy of a melting pot, in the literal sense: a pot that is use to melt and blend metals together.
According to this thoery, the U.S. is a melting pot where different ethinicities are put together, and blend and merge, creating a new, unique culture that takes a bit of each ethnicity.
This has been partly true because it is true that American culture has many influences from each of the immigrant groups that the country has been home to.
However, there is also a form of Mainstream American culture that has been gaining traction in recent decades, and that dillutes immigrant cultures more easily. (the use of English language, Christianity, Republican Federalism, and even Fast Food).
