The great advantage that the United States military forces had during the Vietnam War was that they had superior firepower. U.S. Army and Airforce had more powerful weapons. On the other side, a great disadvantaged that caused them many problems was the difficulty of the landscape. For that purposes, they relied totally on South Vietnam troops that were the locals.
The other options of the question were, a) they had better knowledge of the landscape, c) strong South Vietnamese support, and d) clear territorial goals.
Industrialization played a major role in World War 1. It allowed for new machinery to be produced and at a much fast rate than ever before. This increase in technology combined with old war tactics led to total carnage that shocked the world.
