Answer:
The economic difficulties were high rates of unemployment, hunger, and a destroyed industrial sector.
Step-by-step explanation:
One of the main consequences of the First World War was the death toll. Altogether, about 13 million soldiers and civilians died in the conflict and another 20 million were injured or maimed. These absurd numbers - which are justified by the new armaments built with the technological advance of the Industrial Revolution - lead the conflict to be called the "Great War."
So many deaths and injuries did not only impact the moral of the countries, but also had economic consequences, since the States lost significant portions of the active male population.
Thousands of deaths were caused by hunger. The shortage of food was not only justified by the international sanctions imposed on the country, which hindered imports, but also by the fact that the industry turned completely to war during the conflict.
In addition to human losses, the material damage was immense. The infrastructure of the European countries was deeply affected and the economic crisis caused by the high costs of the war generated unemployment and hunger.
