Answer 1

The factors that led to the United States entering World War I were the sinking of the Lusitania, the Zimmermann telegram, and unrestricted U-boat warfare.

Step-by-step explanation:

The sinking of the Lusitania, the Zimmermann telegram, and unrestricted U-boat warfare were all factors that led to the United States entering World War I. The sinking of the Lusitania, a British passenger ship, by a German U-boat in 1915 resulted in the deaths of 128 Americans and increased anti-German sentiment in the United States. The Zimmermann telegram was a secret communication intercepted by the British and revealed Germany's plan to support Mexico in attacking the United States, further angering Americans. Unrestricted U-boat warfare by Germany, where submarines attacked any ship without warning, including non-military vessels, pushed the United States to finally declare war on Germany in 1917.
