Answer:
B. the Midwest
Step-by-step explanation:
The people that have German, Polish, and Scandinavian origin in the United States, tend to be concentrated the most in the Midwest region of the country. There's a very simple explanation for this. In the period when there was a policy about settling more toward the west, which in that period was the Midwest, as the settlers were concentrated around the East Coast, there were some very lucrative offers. The people that were going to move in in this region were going to get very large pieces of land for farming for free or for very small price. This attracted lot of people, as they were given the chance to be farmers and start their lives all over again. In Europe, the situation was not the best in Poland, Germany, and Scandinavia in this period, and lot of people were migrating in the US. As they came upon this initiative, they accepted the offer gladly, so almost all of them settled in the Midwest. There were so many people from these countries that settled, that the Germans for example are actually the largest ethnic group of which the people claim ancestry in the United States.
