Answer: C-focused on mining and agriculture
Explanation:
As the early Americans adhered to the Manifest Destiny and expanded to the Western part of the Continent, they engaged in different activities from their Northwestern counterparts.
The territories that the Americans took over to the west had fertile land for agriculture as well as rich mineral deposits which led to minning. This often put them at loggerheads with the Native Americans and differentiated them from the North Eastern states which were more industrialized.
The Treaty of Versailles helped pave the way for the Nazi party to gain control of Germany by creating resentment and anger among the German people. Many German people were very resentful of their government (the Weimar Government) for having signed the peace Treaty in June 1919, since the terms of the Treaty were indeed very harmful to Germany: it took territory from the country, it forced it to pay reparations, and (and this term really caused indignation about the Germans) it blamed it and her allies for having started the war.
Since the Weimar Government was not popular and the country was facing tremeduous economic and social problems, the Nazis were able to gain the support of the German people, and eventually had the control of Germany.
