The corect answer is False.
Step-by-step explanation
Throughout the twentieth century (from 1900 to 1999), the United States received millions of immigrants from different parts of the world, Asians, South Americans, Europeans, Muslims, Hispanics, among others. In the case of Asians, it can be affirmed that their arrival occurred due to the gold rush since the 19th century and continued to expand throughout the west coast, mainly California, where the Asians established a "Chinatown" in the city of San Francisco, as a way to isolate the Chinese people in one place. On the other hand, in the case of Hispanics, they were motivated to come to the United States because of the great labor supply of that country compared to their countries of origin, for this reason throughout the 20th century, large numbers of migrants arrived Hispanics in search of work who stayed mainly in the Southwest, where they took advantage of the economic boom in the United States and where they found jobs in all areas, such as manufacturing and agriculture. According to the above, the sentence of the question is FALSE, because Hispanics did not settle on the west coast, nor did the Chinese settle on the southwest.
