Answer 1

Unrestricted Submarine Warfare prompted the U.S. to enter World War I due to concerns about safety and loss of American lives.

Step-by-step explanation:

The factor that prompted the United States to enter World War I by raising concerns about its citizens' safety and the loss of American lives was Unrestricted Submarine Warfare. This was a naval tactic used by the Germans, in which submarines attacked and sank vessels without warning, including civilian ships. The sinking of the British passenger liner, the RMS Lusitania, by a German submarine in 1915, resulted in the loss of 128 American lives and intensified public outrage in the U.S. Eventually, this led to the U.S. joining the war in 1917.
