Answer:
Correct answer is D cultural assimilation
Explanation:
D is the correct answer because it refers to a wide process of total lost of previous cultural pattern, and adoption to the new system of values.
A is wrong because it refers to multiple cultures who are cohabiting in one place.
B is wrong because it would mean that some aspects of previous culture are preserved.
The same goes with C because it refers to people who have different ethnic backgrounds in the family.
Because throughout the nation’s history, various people from many countries (primarily European) have immigrated to the country. For example, there were many Irish, Italian, Chinese, and German immigrants in American cities during the early 1900s. Even today, there are still some immigrants, such as those from Latin America and some Asian countries.
The air masses that have the greatest influence on weather conditions in the Midwestern United States are continental polar.
This air masses come from the north, they are heavy, low, cold and predominantly dry air masses, and are most intense in the colder part of the year. But they are not the only one, even though they are the dominant ones, the tropical warm and wet climate also has a big influence, especially in the warmer part of the year, and it's influence is gradually increasing.
I need more context in order to properly respond to this.
