Answer:
The answer is realism.
Explanation:
As the paragraph says, realism attempts to represent a subject in a true, non-artifcial way. In other words, it avoids any unlikely or supernatural elements. It is also known as naturalism.
Although Gustave Courbet was seen as the leader of realism in his time, realism is arguably a matter of technique and not a period in art history.
If you’re referring to the Treaty of Versailles:
Germany opposed the treaty because it blamed the war on them.
Colonies in Asia and Africa opposed the treaty because after helping fight the war, they were not granted what they traded for when fighting for the war.
Japan and Italy lost land and didn't get what they were promised.
