Question

How did the entry of the United States into World War I influence the conflict?

It put a strain on Allied resources because United States troops were short of
supplies and training.
It helped the Allies stop a German offensive and support a counteroffensive that
led to Germany's defeat.
It had little impact because Germany's naval blockade prevented many United
States soldiers from reaching Europe.
It initiated an offensive that pushed into Germany and immediately captured the
capital of Berlin.

Answer 1

It helped Allies stop a German offensive and support a counteroffensive that led to Germany's defeat.

Step-by-step 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.
