The Allied faction, most notably the British, has gained the upper hand during the first world war due to their acquisition of various oil fields. The oil has powered their military vehicles most notably its naval fleet and the introduction of Mark V tanks that posed significant advantage at the course of the war.
Answer:
It helped Allies stop a German offensive and support a counteroffensive that led to Germany's defeat.
Explanation:
I'm not entirely sure of the answer, but through the process of elimination I've made my way here. I know it's not the first one, because although we had a poorly trained military, we were not short on supplies.
I know it's not the third one, because obviously the United States entering the war had an effect on it. Even though there was a German blockade we most likely could've gotten through it.
It's probably not four because saying that the United States entering the war immediately caused the capture of Berlin is a bit extreme- all though the United States entering the war caused it to end quickly, it was still around a year.
The correct answer is - A war between the colonies and Britain.
After the Declaration of Independence and what it actually meant and encouraged the people in the colonies to do, the expected reaction from the British Empire was that it will try to use military force in order to keep the colonies under its control. And the expectations were true, as the British did launched a military campaign against the rebelling colonies, but the Americans were prepared for this and managed to withstand their ground and gained their desired independence, and that was a major blow for the British, especially from economic perspective.
