Answer 1

The events that led to the U.S. entering the war included the sinking of the Lusitania, the German submarine blockade of Great Britain, and the Zimmerman telegram. Thus, the correct answer is D) All of the above.

Step-by-step explanation:

The events that led up to the U.S. entering the war included:

1. Sinking of the Lusitania: In May 1915, the German U-boat sank the British passenger ship Lusitania, resulting in the deaths of 128 Americans. This event shifted American public sentiment towards entering the war.
2. German submarine blockade of Great Britain: Germany used its submarines, known as U-boats, to attack any vessel suspected of carrying military supplies to the British or French. This included American ships, leading to further anger and pressure for the U.S. to enter the war.
3. The Zimmerman Telegram: The interception of the Zimmerman Telegram, a top-secret communication between German officials, revealed Germany's plan to invite Mexico to join the war on the German side and invade the United States. This further fueled public sentiment for U.S. intervention.

Thus, the correct answer is D) All of the above.
