Question

Which of the following was NOT one of the key factors that influenced the US to enter World War ONE?

Germany trying to convince Mexico to attack the US
The sinking of the Lusitania by a German sub
Germany boycotted US made goods shipped to Europe
Germany's unrestricted submarine warfare

Answer 1

I believe the answer would be Germany BOYCOTTED U.S made goods shipped to Europe. This was because Germany sank the Lusitania and tried to convince Mexico to attack the US, this enraged the public, also Germany’s unrestricted sub warfare was a crime which also changed opinion leaving the only answer to be the BoyCott of goods. Hope this helps!
