Sorry if It’s wrong
Answer:
D, C, and A.
Explanation:
During the late 1800s new ways of American farming improved thanks to the development in farm technology and machinery. The railroad system made possible the transportation and commercialization of goods from the country to the cities. There was a replacement of the horse power, which was used to plough the land by the steam tractor, in which it allowed farmers to introduce a great variety of crops and wheats.
Well Britain and France took massive loans from the United States for war supplies. Also the fighting was taking place on French soil which destroyed all the farms and all the farms were fighting the Germans which meant that American farms where needed to grow more crops faster which meant they took out loans and used them to buy tractors to help feed the French and little bit to Britain and also Belgium.
