Name the four reasons the US finally joined the war?

Our entry into ww1 reasons-

1. germany’s submarine attacks on passenger and merchant ships in 1917.

2. the difference between the triple alliance and triple entente.

3. militarism, nationalism, alliances, imperialism etc..

4. the assasination of archduke franz ferdinand (between austria and serbia)

if it’s 4 reasons the answer ur looking for is probably #3
