Which factor contributed to the entry of the United States into World War I? (3 points)

-Unrestricted Submarine Warfare

-Zimmerman Telegram

-British ties with American culture

Explanation:

Germany had taken a huge risk by sinking American cargo vessels and sometimes civilian vessels to stop any trade between England. Also, a telegram was sent to the Mexican government offering a German military alliance if the US ever entered the war. Britain intercepted the telegram and brought it to American officials which outraged them.  Britain had promoted the Americans to join the war and the American population was very sympathetic to Britain.
