Answer:
B. nationalism.
Explanation:
The nationalism that originated in the times of the French Revolution changed over the years. By the beginning of the 20th century, most European peoples identified with a nation state and were willing to defend or go for interests of a homeland.
The nationalism fueled competition over economic, social aspects, and was best explained by the rivarly between the French and the Germans.
Prussian -French war caused the tensions to increase among the former.
The rivalry was also felt between the English and the Germans over the seas. The increased trade and foreign trade also was a important force that brought tensions in other continents.
The concept of Nationalism emerged to the most, in the military propagandas, and the racial and ethnic policies from the Central `powers.
<em>A fierce state of things promoted a national army in numbers that were unprecedent to the times- and the war effort ultimately was propeled by nationalistic groups that prevailed among societies.</em>
I asked that question too
The market forces regulate production to align with the supply. As demand increases, the supply is increased to meet the new demands. when the government controls production there may be a surplus of goods that are not needed and a scarcity of basic goods. The economic principles that inform production may be undermined by political agendas.
Maximilien de Robespierre was executed because of the things he did
during his lifetime. He was an important figure during the French
Revolution, as well as the Reign of Terror, which was a time of extreme
violence then. Robespierre executed many opponents himself, which is
something that was easy for him to do given his important role in the
society. Because of his evil doings, he was ultimately executed himself,
being the one who instigated the Reign of Terror.
